INFORMATION

GENERAL TECHNICAL FIELD

The present invention relates to the field of pipes for the extraction of oil and gas.

STATE OF THE ART

Oil and gas extraction pipes are used to drill wells and for extraction, in order to achieve greater depths.

These pipes have threads at each of their ends that allow them to be connected together, either directly or through intermediate elements.

The threaded ends of the pipes are called male ends, while the tapered ends of the pipes are called female ends. Throughout this patent application, we will generally use the threaded ends of an extraction pipe, which interchangeably designate the threaded or tapered ends of the extraction pipes.

MEXICAN INSTITUTE OF THE WOPIIDA ·

In accordance with the practice of an erPlá expert^TWatellaf protector that fits the male end of a pipe · 55τΐϊίΓΤϋΗ1ΐη3 male protector (or pin), and a protector that fits a female end of a pipe is called a female protector (or box).

Another problem with extraction pipelines commonly used for drilling in the oil and gas industry and extraction operations is their logistical management and the determination of their properties or the information that concerns them.

In fact, extraction pipes are typically packaged in batch form, which complicates the handling and measurement of a single pipeline between its manufacture and use on site.

Several studies have been attempted to modify the extraction pipes so that they implement means of marking and tracing them. However, these studies, carried out over the past 5 to 10 years, have not provided the desired result as they have consistently resulted in deterioration of the mechanical properties of the pipe, which is prohibitive.

The present invention aims to propose a solution to these problems of logistical administration and identification of extraction pipes that has no impact on the mechanical properties that has no impact on the mechanical properties of said extraction pipes or the equipment associated with them.

DETAILED DESCRIPTION OF THE INVENTION

Figure 1 shows a threaded protector 1 of an extraction pipe 2 associated with a module 3 that allows the storage of information.

θ

IMPI

Guard 1, as shown, is industrial

<img file="MX343285B_D0015.tif" />

advantageous by injection of plastic and / or composite material (such as metal-plastic protectors), which can be transparent or opaque; usually thermoplastic polycarbonate or polyurethane.

As a variant, the protector 1 is made of acrylonitrile polypropylene or styrene butadiene, and can be reinforced with metal, metal-plastic or composite parts.

The protector 1, like the one shown, includes a tubular body 11, provided with an internal or external thread 12 to complement the external or internal thread of an extraction pipe 2, and an external ring 13 defining an increase in the external diameter of protector 1, so that it supports the possible Impacts to which pipe 2 may be subjected. The various holes 14 are defined between the tubular body 11 and the outer ring 13, said holes being normally delimited by the radial rods 15.

Shield 1, as shown, is associated with a cap 16 located at the free end of the shield.

The cover 16 includes a central plate 17 and bases 18, said base being designed to cooperate with the blocking means such as pins arranged on the body of the protector 1, and therefore, to hold the cover 16 in position on the protector one.

The central plate 17 can take various forms. In the modality shown, there is a disc, which allows the complete closure of the

<img file="MX343285B_D0016.tif" />

localized opening in the free end of the protector 1 its fluid tightness. As a variant, not completely closing the opening in said free end of the protector 1; This may, for example, be a strap running along a diameter of the protector 1.

Figure 1 shows a variant in which module 3 is fixed on protector 1. As a variant, module 3 can be fixed on cover 16, or even on pipe 2 as will be seen later in figure 2 The joining of module 3 can be achieved by any suitable technique, so as to ensure that it is kept in position without damaging module 3, protector 1, pipe 2 or cover 16.

In particular, the following modalities can be mentioned: the protector 1 defines an internal hole 14, where the module 3 is positioned; the internal hole (s) 14 of the protectors 15 can be filled with resin, which makes it possible, in particular, to ensure that the module 3 is kept in said hole 14 of the protector 1;

module 3 is attached with adhesive or welded on said protector 1 or cover 16;

module 3 is fixed on said protector 1 or cover 16 20 by means of fasteners (such as rivets or a screw-nut set preferably made of plastic to limit any type of corrosion);

IMPI

<img file="MX343285B_D0017.tif" />

. X *. . . 'Νίτηυτο MEXICAN, protector 1 or cover 16 can terte ^ j ^ a ^ ci in the form of a stem on its surface. Module 3 the signature of a ring (or the shape of which includes a ring) can be positioned around the outgrowth. The upper end of the outgrowth is then heated to deform it, and therefore, to obtain a diameter greater than the diameter of module 3 (or the ring of module 3) so as to ensure module 3;

module 3 can be stapled to protector 1 and cover 16, mounting module 3 through force;

- module 3 can be connected by means of a plastic, elastomeric, metallic or cordage ring to protector 1 or cover 16;

the module can be fired, particularly on the strap 31, which will be described later referring to Figures 2 and 3;

- module 3 can be welded on said protector 1 or cover 16 (such as by means of ultrasonic, friction or mirror welding);

protector 1 or cover 16 can be over-molded around said module 3, the latter being, if applied, advantageously positioned in an envelope that protects it during molding so as to avoid deterioration of the module.

As a variant, the protector 1 is made closed, that is, with a wall made directly by injection in the place of the cover 16, shown in figure 1. Depending on the desired use, this wall can be

<img file="MX343285B_D0018.tif" />

<img file="MX343285B_D0019.tif" />

retained or removed by machining so that tkswIot open 1 like the one shown in Figures 1 -3, with ol oual_t a lid is normally associated.

In this case, where this wall is retained, the module can be applied directly to this wall, which is advantageous in terms of manufacturing costs, and makes the module 3 inseparable from the protector 1.

Figures 2 and 3 show two variants, where the protector 1 is provided with a cover 16 mounted in a pivotal manner by means of a hinge.

Figure 2 shows an exploded view of a first variant, while Figure 3 shows an assembled view of a second variant.

At this point, the cover 16 consists of a central plate 17, provided with two bases 18 on each side of this central plate 17, a first of these bases being provided with projections 19 designed to cooperate with the holes 20 made in the protector 1 , here in its outer ring 13, so that it forms a hinge, the second of these bases forming a retention means 21 that can be stapled to the complementary means 22 of the protector 1, which can be decoupled by the user in a way that allows the pivot movement of the cover 16 around said hinge.

Furthermore, pipe 2 is also equipped with a collar 30 hermetically mounted around said pipe 2, to which it is attached

<img file="MX343285B_D0020.tif" />

IMPI a strap 31 that has a free end, in proximity to Tcu ^^ s module 3. This collar 30 is made of manara Y2nt? J^nga of a material that can be cut by the user, of plastic, for example, so that it offers sufficient resistance to guarantee that the collar 30 will be supported 5 on the pipe 2 in the event of impacts or accidental forces, while the user still you can take it apart.

All or part of the collar 31 can be protected from impacts by a provision of the protector 1, normally an excrescence to protect the union head (s) of the collar 31. Therefore, 10 before the insertion of the pipe 2 on the open well, the user can cut the collar 30 so that it separates it from the pipe 2.

This strap 31 is typically an automatic restraint strap, eg, of the hook and bracket type, eg, the auto restraint straps sold under the name Velero ™, or any other suitable means, eg, fasteners removable mushroom shaped that are stapled together (normally sold under the name Dual lock ™, by means of complementary magnetic straps or a system including a V-belt 31 which is forcibly stapled in a dovetail shape provided on the protector. It is also possible to use a combination of the items sold under the names Velero ™ and Dual Lock ™, for example by associating the support portion or hook portion of a Velero ™ with a Dual Lock ™ tether strap. The protector 1, and the cover 16, are normally

I .Μ Ρ i provided with additional fastening means, res ^^ Zátri &amp; rítg

Industrial I that allow the user to attach the strap 31 to the protector 1 and to the cover 16, when they are positioned at the end of the pipe 2.

Belt 31 is advantageously dimensioned such that, when attached to guard 1 and cover 16, module 3 is positioned substantially in the center of center plate 17 of cover

16.

In the embodiment shown in figure 2, the protector 1 includes a slot provided in its outer ring 13, so that it allows the passage of the strap 31, so that it is protected by the protector 1 from Impacts or external forces. The protector 1 may also include rods, for example, in the body 11 of the protector 1, so as to protect the strap 31.

In the variant shown in FIG. 3, this passage for the strap 31 corresponds to the portion of the outer ring 13 that includes the means 22 complementary to the fastening means 21 of the cover 16. This variant also makes it possible to keep the cover 16 closed at all times. belt 31 is in place.

In this variant, protector 1 also includes notches 24 projecting from the free end of protector 1, these notches 24 being typically designed to allow the user to insert a tool into them to tighten or unscrew protector 1 from pipe 2, and also achieve additional protection against longitudinal impacts.

<img file="MX343285B_D0021.tif" />

Figures 4 and 5 show another modality i is associated with a harness that allows this to be attached to the pr ^ tfíftpr? v is positioned on the free end of protector 2 without requiring specific means on protector 1 or on pipe 2.

More precisely, the harness 5 includes a band 51 from which two straps 52 and 53, respectively, extend. Harness 5 is normally made of polyester and / or neoprene.

The band 51 has two free ends 54 and 55, which have complementary fastening means 56 and 57, usually automatic fastening elements such as those described above. These complementary fastening means 56 and 57 are normally positioned on two opposite faces of the band 51, so that when the two free ends 54 and 55 of the band 51 overlap, said complementary fastening means 56 and 57 can be coupled.

The free ends 54 and 55, each also includes an opening, 58 and 59, respectively, designed to align when the two free ends 54 and 55 of the band overlap and the complementary fastening means 56 and 57 are coupled, so that they are inserted into a closure element 60 of the band 51; usually a rivet like the one shown in figure 5.

The band 51 of the harness 5 is dimensioned so that the closure element 60 holds it tightly on a protector 2 that

<img file="MX343285B_D0022.tif" />

industrial has a certain diameter, so that the removal 2 ^ protector 2 requires the removal of the closure element 60.

<img file="MX343285B_D0023.tif" />

The two belts 52 and 53 extend from the band 51, so that they are diametrically opposed when the band is closed 5 around a pipe 2. The length of the portion of the band 51 that separates the two belts 52 and 53 is by therefore advantageously equal to the outer perimeter of the pipe 2 on which it is intended to join the harness 5.

Each of these straps therefore has a free end, 61 and 62, respectively.

The two straps 52 and 53, as shown, can be defined as a support strap 52 and a tether strap 53.

The support strap 52 includes a module 3 like the one shown above, normally positioned in proximity to the free end 61 of the support strap 52.

The free ends 61 and 62 of belts 52 and 53 are advantageously equipped with complementary fastening means 63 and 64, usually automatic fastening elements such as those described above. These complementary fastening means 63 and 64 are normally positioned on a different face, so that the two free ends 63 and 64 of the straps 52 and 53 overlap, said complementary fastening means 63 and 64 can be coupled. Straps 52 and 53 and module 3 are advantageously dimensioned and positioned so that when the harness is attached to

<img file="MX343285B_D0024.tif" />

a pipe 2 and the two straps are fastened using complements 63 and 64, module 3 is positioned at the free end of the protector, normally on its cover 16.

Referring to figure 5, in which a pipe 2 is shown at the end thereof, a protector 1 is placed as the one previously described, pipe 2 is wrapped by means of band 51 of harness 5, subsequently the two straps 52 and 53 are fastened in the protector 2, on their free end; on its cover 16 if there is one. It is then possible to ensure the positioning of the harness 5 on the pipe 2 using a closure element 60 as previously described.

This particular embodiment then makes it possible to take advantage of a module 3, a pipe assembly 2 and a protector 1 that does not have dedicated fastening means, and without requiring that the protector 1 be made of a particular material, or that the joint surfaces of module 3 are 15 specially prepared or cleaned to allow their union.

Additionally, the closure element 60 makes it possible to ensure that the module 3 remains firmly attached to the selected pipe 2; in fact, by separating the module 3 from the pipe 2 that requires the destruction of the harness 5, the module 3 or the closure element 60. The user 20 can then clearly identify a module 3, which has been separated from the pipe 2 by which was initially clamped, the closure element 60 which serves as a seal or vestige of rupture.

In addition, belts 52 and 53 have the advantage of being ^ ^ Sc ^^^ OT ^ of being assembled and separated by means of their complementary snip-off means 63 and 64, the user can always carry out the operations of verification and inspection of pipe 2 such as the Trend operation. In fact, it is only necessary to separate the two belts 52 and 53, which remain firmly attached to the pipe 2 by means of the band 51, remove the cover 16, if any, from the protector or the complete protector 1, perform their verification operations, then replace the cover 16 or the protector 1, and finally fasten the two straps 52 again and

53 together.

Furthermore, the use of a band 51 that includes an internal elastomeric coating, such as neoprene or cellular neoprene, makes it possible to provide a cup suction effect on the perimeter of pipe 2, and therefore, strengthens its ability to be maintained. in position around pipe 2.

Finally, by ensuring the positioning of the module 3 at the free end of the protector 1, that is, at one end of the pipe 2, the reading of the information contained in the module 3 is considerably facilitated compared to a module subject to the periphery of pipe 2 or protector 1.

In these modalities, the module 3 is connected with the pipe 1, which makes it possible to avoid any risk of accidental separation between the module 3 and the associated pipe 2, for example, when the protectors 1 are removed for a verification or lir operation pipe 2.

IMPI

<img file="MX343285B_D0025.tif" />

More generally, if the mode shown in Figure 1, Figure 2, Figure 3, or Figures 4 and 5 are considered, Module 3 is connected so that it can be removed to Pipe 2, either through the protector 1 or its cover 16, or the connecting means such as a collar 30.

Placing module 3 on cover 16 has several advantages. In fact, transmission of module 3 can be inhibited due to the metallic nature of pipe 2. Therefore, by positioning module 3 on cover 16 of protector 1, module 3 is kept as far away from the pipe as possible. 2 and the interference that the latter could produce in the module emissions is then reduced.

In the case where the module 3 is positioned on the cover 16 of the protector 1, said cover 16 is then advantageously connected to the body of the protector 1 so that it cannot be dissociated from it. Said connection can, for example, be achieved by means of a light chain, a cable, a cord or even a hinged connection, such as in the embodiment of Figure 2.

Module 3 is advantageously arranged so that 20 is not exposed to Impact or external forces that could damage it, for example, in reinforcements or holes.

Module 3 is normally an RFID module that contains an RFID tag, advantageously of the UHF (ultra high frequency) type, it is

IMPI say, RFID modules that use frequencies coflíjWWJlflS ^ d

WIMMTRIAL

<img file="MX343285B_D0026.tif" />

range from 860 MHz to 960 MHz. Module 3 can also be associated with a GPS-type positioning module or a GPRS module, said modules being well known in the state of matter and allowing the pipe associated with the module to be located , which makes it possible, for example, to monitor real-time pipeline orders and deliveries, or even locate inventories.

Such a GPS or GPRS positioning module is normally associated with a pipe bundle, i.e. a large number of pipes connected together with transport straps and forks to pack and transport them. The positioning module is advantageously positioned on transport belts or a fork of the beam, so that they are well separated, so that they do not interfere with the emission of the positioning module.

Therefore, it is possible to geographically monitor said batch by packing it up to the site of use thanks to the positioning module, which is monitored by the individual of the various pipes at the site of use is then achieved by module 3, which is, for example, of the type

RFID.

By associating a positioning module with a pipe bundle in such a way, the number required is reduced, said modules being more expensive than RFID type modules.

The module modules of the pipes advantageously, by packaging.

It should be noted that RFID technology (Identification of

Radio Frequency, on which NFC (Near Field Communication) technology is based, is well known in the art and will not be described in detail in the present description. RFID technology employs modules commonly referred to as markers, which can be glued on or incorporated into objects, including an antenna associated with an electronic microcontroller, which enables them to receive and respond to radio searches issued by a transceiver.

According to a particular modality, ultra high frequency technology is used, that is, normally from 860 MHz to 960 MHz, known under the designation of passive UHF, where module 3 does not include a battery, or an ultra frequency module active discharge equipped with a battery.

The module includes, for example, information encoded in 512 20 bits. Typically, the following encoding can be used:

a 30-bit encoded unique identifier, which makes it possible to encode the unique identifiers for 2 to 4 million pipes per year over a period of 50 years;

IMPIOUS"-?

the length of the pipe: in metH8§ ^ Jpf ^ g | ® up to almost one centimeter; for pipe lengths ranging from 0 to 15 m - 1,500 values ​​in 2,048; that is, 11 bits;

pipe diameters: typically 10 diameter values ​​at 32 values, or 5 bits;

thread type: 10 different thread types encoded in values, or 5 bits;

pipe thickness: 50 thickness values ​​encoded in values, or 6 bits;

- the name or abbreviated identifier of the pipe manufacturer: normally 6-bit coded;

the name or a short identifier of the customer (the receiver of the pipes, for example): normally encoded in 8 bits; for a total of 71 bits occupied by this information.

The remaining bits of the 512 bits of memory in the module are used to store the most recent events experienced by the pipeline (place, date, reader, action), each of these events being normally encoded in one hundred bits or something similar. Therefore, it is normally possible to record in the module between 3 and 5 of the last events in the life of the pipe.

According to a particular embodiment, the protector 1 and / or the pipe 2 includes a second identification means, normally in the

form of a serial number of a barcode, a medium that is normally used only in the case of module 3 fajla ----------- It will be seen that Figures 1, 2, 3, 4 and 5, have a single end of pipe 1 equipped with a protector 2. It will be readily understood 5 that a similar arrangement is found at the other end of pipe 2.

For example, in the case of an extraction pipe 2, which includes a male end and a female end, the two ends are respectively equipped with a male protector and a female protector, each of these protectors 1 being then advantageously provided with a module 3.

Therefore, the present invention makes it possible to have available means that allow rapid and automated identification of the extraction pipes, without having a negative impact on the characteristics of the extraction pipes themselves. In fact, the installation of module 3 containing the information regarding pipe 2 about protector (s) 1 or the cover (s) 16 of protector (s) associated with pipe 2 makes it possible not to make any structural modification of the pipe 2 itself, unlike the previous methods of a person skilled in the art who naturally could try to implement some means to identify the pipe directly on the pipe.

Figure 6 schematically illustrates a method for monitoring an extraction pipeline associated with a protector and a module as defined above.

Step E1 of pipe association with

This step E1 is normally located after the pipe is manufactured, during its packaging.

At that time one or more modules are associated as previously described, for example, one module at each end of the pipe. Two variants are distinguished, depending on whether the module is attached to the protector pipe itself.

In the case where the module is associated with the protector, which corresponds, for example to the modality shown in Figure 1, the threads of the protectors are associated with said pipe, normally a protector at each of its ends, before packing it in a batch and transporting or storing it.

In the case where the module is associated with the pipe, which corresponds, for example, to the modality shown in Figures 2 to 5, one or more modules is associated with the pipe, for example, joining it by means of plastic collars. , which are fastened with clamps on the body of the pipe near its ends or by means of harnesses, such as those previously shown.

During this association between the extraction pipeline and the module (s), one or more items of information that relate to the pipeline, are applied to the module (s).

Various modes are possible to accomplish this step E1.

IMPI

The pipeline, for example, can be a single identifier, normally defined by its ^F?^hripanto The module (s) then also has this identifier applied to them.

As a variant, the information contained in the module advantageously corresponds to one or more of the following characteristics of the associated pipe:

the length of the pipe, the inner and outer diameter of the pipe, the type of tapping or tapering of the pipe, the thickness of the pipe, the geometric properties of the threaded pipe.

The identification of a customer the ability to trace the history of the pipe (referring in particular to various places, dates and actions) a type of coating present on the pipe thread an order number a unique pipe number

As a variant, the module (s) is already provided with a unique identifier; The pipe identifier to its properties (for example, its manufacturer, its dimensions or any other properties that allow it to be characterized) are then connected to that module (s) associated with it in a database. The use of unique identifiers

IMPI will make it possible to mistakenly identify the protectors ^^ $ ^ ¡

identifier.

In the case where the module includes a unique identifier for the pipe or the protector, this identifier is then associated with a database that includes the identifiers of the different pipes and the protectors equipped with said modules, as well as the information associated with such pipes or modules.

In particular, the articles of information that may be mentioned are:

- the geometric properties of the pipe, the reports of the tests carried out on the pipe, the batch from which the pipe is extracted, and its place of manufacture.

the history of the actions regarding the pipe and / or the module.

Information that relates to a characteristic of the extraction pipeline being written to the module during the packaging of the pipeline, and therefore during the placement of the protectors on the threaded ends of the pipeline, ensures that the information contained in the module in fact, corresponds to the pipe in which the module is placed.

Step E2 of reading the information

The information contained in the module is read through appropriate means of communication.

This reading of the information contained in the module can occur in various situations, among which we can mention, without limitation:

inventory and inventory verification, monitoring of orders or batches of extraction pipes, before using the pipes at a drilling or extraction site, during the extraction of threaded pipe protectors so that the pipes are identified and labeled used on the site.

The reading of the information contained in the module can be achieved on demand or automatically during the passage of the protector in proximity to a certain location.

In the event of a module 3 failure, the information it contains cannot normally be read, or is only partially read. In these cases, if protector 1 and / or pipe 2 is equipped with a second means of identification such as a serial number or a barcode, the operator can identify the pipe and / or protector by means of this second means of identification.

Step E3 of module processing.

After reading the information contained in the module, this information is processed by the communication medium, which is advantageously designed to perform all or part of the following operations;

the segmentation of the information read in order to extract only the specific information desired by the user, compare the information read with the information stored in a database.

In the modalities where the information read is compared with the data stored in a database, the communication means are typically designed to extract the data from said database corresponding to a search by the user.

This step E3 is normally followed by a step E4 which consists of displaying the desired information.

Figure 7 shows an example of a system 10 designed to implement the method defined above.

System 10 includes several pipes 2, each of said 20 pipes being provided with protectors 1 and modules 3, such as those presented previously in Figures 1 to 5, as well as the communication means 4 that make reading possible, process and display of the information contained in module 3.

The communication means 4, normally rtdwyen antennas 41 designed to detect the 3 ”modules and for the infiH4wacjóu__ that are contained at a defined distance.

This distance, and therefore the nature of the antenna 41 5 used, is normally selected according to the location and function of the antenna 41.

By way of example, for an antenna 41 positioned in a storage area, it is advantageous to select an antenna 41, which has the ability to detect modules 3 located over the entire area of ​​the storage area.

For an antenna 41 positioned in a specific area such as the area for preparing the pipes 2 to descend into the open well or in a storage zone where the next pipe 2 that is intended to be brought down into the open well is stored, it is advantageous to select a short-range antenna 41 in a way that ensures that only the modules 3 of the pipes 2, which are carried in said area, are detected and read.

The short distance antennas 41 can also be positioned on the tools used to unscrew the protectors 1, which, in this way, brings them in proximity with the modules 3 connected to the pipes, to the protectors or to the covers.

It is also possible to place the antennas 41 in the protector tanks, where the protectors 1 are stored after the use of the

Such an antenna makes it possible, for example, to confirm in this way which pipes 2 have actually been lowered into the open well or will soon be.

The detection and reading of the information contained by the modules 3, is then achieved directly during the unscrewing of the protectors 1 of the pipe 2 in order to ensure that only the modules 3 associated with the pipe 2 actually being used are identified and read .

Communication means 4 typically includes a processing means 42, such as a processor designed to process the information, which is in the module, as well as the display means 43 that allows the user to view the desired information.

Implementation Examples

A first example of implementation of an aspect of the present invention relates to the operations to verify the extraction pipes.

A user may wish to verify the characteristics of the extraction pipes which are stored as a batch before use or for shipment to a site of use.

<img file="MX343285B_D0035.tif" />

The user is then equipped with a to read the information contained in the iiiÚLÍUtiHL of the different protectors associated with the pipes in question, which can normally be associated with a device such as a laptop, a tablet or a PDA.

The information read from the different pipe modules is then compared with the information entered into a database, which normally includes the following information:

a reference pipe, the references of the protectors associated with said pipe, the characteristics of the pipe; for example, its inside diameter, its outside diameter, its effective length, its weight, its manufacturer, the properties of the threads at its ends,

- reports regarding the pipeline or associated protectors; for example, the reports of the verification carried out on the pipe (normally the operations of verification of the interior of the pipe, usually called trends), other numbers associated with the pipe or the batch of pipes, thus making it possible to determine the destination of the pipeline or batch of pipes.

The user, who wants to check the characteristics in a storage area, or more generally carry out an inventory, can pass the

IMPI nearby pipelines equipped with the modules with industrial led8F430iWftÍ? L all the identifiers contained in the modules ^ subsequently connect them to an existing database so that it obtains the corresponding information with the identified pipelines.

In the case of double reading a pipe, for example, reading the same identifier twice or reading two modules of the same pipe, in the case where the pipe includes a module positioned at each of its ends, this conflict is managed in the database, which connects these multiple measurements from the same pipe.

The user can proceed with the verification of the extraction pipes, for example, verifications of their dimensions, by means of measurement tools, such as a laser measurement device, and then cross-check these measurements with the information contained in the modules of the different pipes.

A second implementation example of an aspect of the present invention relates to the use of pipelines on site, for example, in the case of an open well.

The pipes are sent to the site in batches, later they are taken to the open well where they are assembled so that they are placed from end to end, then they are lowered into the open well.

<img file="MX343285B_D0036.tif" />

<img file="MX343285B_D0037.tif" />

The means of communication such as anS ^^^ SH advantageously positioned in an area to prepare and assemble the pipes before their descent to the Interior of the open well.

The means of communication that are detected automatically, or as a result of a user command, the protectors that are sent in this preparation area, and therefore identify the pipes that are sent there and will therefore be brought down to the inside the open well.

The user can then prepare a list of the different pipes that have been lowered into the open well, in chronological order. In this way, different types of information can be accessed, for example, identifying the position of the pipes in the open well, applying the lengths of the different pipes, knowing the total length of the pipes that have been lowered into the open well. .

Table 1 below illustrates an example of such implementation so that a table is obtained that can be used directly by the user.

In the illustrated example, the user can thus see the different pipes that have been inserted into the open wells and those that are waiting to be lowered, and has information available regarding their insertion order, their individual lengths and cumulative, and the depth at which they are located.

This table is advantageously updated'W'ttempt since each of the media detects IflS fflftUUIorgn 'the¹ ·&gt; »Preparation areas before the descent. The user can then, for example, validate the different pipes since each one is actually lowered into the well. Said table is advantageously shared by means of communication media, such as the Internet, allowing any authorized person to consult the progress of the well, advantageously in real time.

TABLE01

<td>Order</td><td>Pipe</td><td>Total</td><td>Length</td><td>Depth</td><td></td>

<td> 5</td><td>REF5</td><td></td><td>12.01m</td><td></td><td>k_</td>

<td> 4</td><td>REF4</td><td></td><td>11.14m</td><td></td><td>by err</td>

<td> 3</td><td>REF3</td><td>30.62m</td><td>10.12m</td><td>1031.53m</td><td></td>

<td> 2</td><td>REF2</td><td>20.50m</td><td>11.00m</td><td>1041.65m</td><td></td>

<td> 1</td><td>REF1</td><td>9.50m</td><td>9.50m</td><td>1052.65m</td><td>Water well</td>

The information displayed in this way, normally reproduces the following data: pipe number, thread type, pipe diameter, pipe length, the sum of the lengths of the pipes that were lowered into the open well.

For this type of application, it is advantageous to read only the information contained in the module, without including the resulting or connection to

<img file="MX343285B_D0039.tif" />

a database, so that the system does not disconnect from the network, which is particularly seen at places where extraction pipes are used.

The present invention exhibits numerous advantages compared to conventional devices and methods.

First, the present invention proposes to achieve monitoring and tracing of extraction pipes, which makes it possible to gain quick and easy access to the characteristics and information regarding an extraction pipe. The present invention also makes it possible to insure against accidental dissociation of the pipeline and the module containing the information regarding it, while still allowing its removal before lowering into the well.

The user can then gain access to this information that starts from the information contained in the module. Therefore, it is no longer necessary to carry out the measurement operations on site, the geometric information regarding the extraction pipeline in question can be quickly retrieved thanks to the information contained in the module.

The number of manipulations carried out on the pipe and the protectors, therefore, is considerably reduced.

Stocks and monitoring order are simplified, and can be updated in real time. Counting operations are also simplified.

'MPI

In addition, in the event of a complication or unification with the use of a pipe, the present invention allows the traceability of the different quality checks of the pipe in question.

For example, if an incident is detected at a given depth while drilling a well, information regarding the effective lengths of the different pipes that have been lowered accordingly into the well makes it possible to determine which pipe is located at the depth of the incident. The user can then have access to different information regarding the pipeline; for example, reports of different tests performed on pipelines, such as trends.
