Degradable material time delay system and method.
Abstract
A delay tool and a method includes a mechanical retention element, a reservoir for containing a reactive fluid, a drive device and a well drilling device. When a stored energy is applied to the well drilling device, the drive device is driven and makes it possible for the reactive fluid in the reservoir to come into contact with the mechanical retention element. While the mechanical retention element is subjected to a change in its shape due to a chemical reaction, a stored energy that is applied in the well drilling device is delayed by a predetermined delay. The amount of the predetermined delay is defined by factors that include the reactive fluids, the concentration of the reactive fluids, the geometry and size of the mechanical retention element. The most representative figure of the invention is number 1.

The present invention relates generally to tools for drilling the bottom well. Specifically, the invention attempts to use a known fluid that reacts with a degradable mechanical element that allows a known delay between a trigger event and a functional event.
BACKGROUND TECHNIQUE AND BACKGROUND OF THE INVENTION Background of the Prior Art
In crude oil and gas extraction applications, there is a need to have a certain length of delay between events activated by pressure so that the system can be tested under pressure before the next event could proceed. This system cannot be controlled with any other means besides the pressure application. The fluid restriction means of the prior art system utilizes a complex system of microscopic passages that measure the fluid. Therefore, there is a need for economical flow restriction systems of simple and flexible components.
CQfcC I n / RI Π7Ο / νΐΛΙ
Within a tandem in a gun chain assembly, a transfer occurs between the detonating cords to detonate the next gun in the daisy chain gun chain. The detonation can be initiated from the wired line used to deploy the gun chain assembly either electrically, by means of pressure activation or by electronic means. In pipe-borne drilling (TCP) as there is no electric conductor, the onset of pressure-activated percussion is used to detonate. TCP is used to pump up to a pressure in the pipe that reaches a certain pressure that makes it possible for a starter head to launch a firing pin. Subsequently, the hammer bolt starts the percussion starter which starts the detonating cord. There is a need to delay the release of a firing pin for a predetermined time in certain cases so that the tests can be conducted or a detonation delay condition can be detected in a previous gun.
In tandem systems there is an individual detonating cord that passes through the guns. There are no pressure barriers. However, in select start-up systems (SFS) there is a pressure isolation switch between each gun. Each gun is selectively launched through its own detonation train. A detonator feeds on each switch. When the downward drilling gun is punched, the pressure enters the inside of the gun. When the first gun is actuated, the second detonator is activated when the pressure in the first gun switch is moved into the next position by operating a firing pin to make detonation possible in the next gun. All downstream guns are isolated from the next gun by the pressure barrier.
Reel valves are directional control valves that are used as well drilling tools. These allow the flow of fluid in different paths from one or more sources. These usually consist of a reel inside a cylinder which is controlled mechanically or electrically. The movement of the reel restricts or allows the flow, thus controlling the flow of fluid. There are two fundamental positions of the directional control valve specifically the normal position where the valve returns in the removal of actuating force and another is the working position which is the position of a valve when actuating force is applied. However, the prior art spool valves do not have a control mechanism with a predetermined delay for switching from the normal position to a working position.
It is known that well fluids vary in chemical nature and do not always have the same composition. However, the temperature of the well is frequently defined or can be manipulated to achieve a predetermined temperature. Most of the delay elements currently used comprise complex mechanisms and are often expensive. Therefore, there is a need for a delay tool that can use a known fluid or an unknown fluid within a well at a known temperature such that a known degradable element can react and can degrade in the known fluid at the temperature known for a known amount of time so that a predetermined time to activate a mechanism in a device can be achieved.
Deficiencies in the Prior Art
The prior art as detailed above suffers from the following deficiencies:
• Prior art systems do not provide a known degradable element that can react and can degrade in a known fluid at a known temperature for a known amount of time so that a predetermined time to activate a mechanism in a device can be achieved. .
• Prior art systems do not provide a low cost configurable delay flow retention element that is commonly available.
• Prior art systems do not provide a predictable delay.
• Prior art systems do not provide a cost-effective delay solution that is independent of well drilling fluids.
• Prior art systems require bulky and expensive hydraulics.
• Prior art systems require expensive electronics that have difficulty operating at well down temperatures.
While some of the prior art may teach some solutions to several of these problems, the main issue of a predictable delay with known fluids at predetermined temperatures has not been addressed in the prior art.

Well Drilling Delay Tool in the
Fund of the same Preferred Issue that is Integrated into a
Energy Device (0200 - 0600)
As generally illustrated in FIGURE 1 and FIGURE 2 (0200), a tool for delaying the drilling of the well at the bottom of it (0210) for use in a lining of the well drilling comprises a reservoir (0211 ) to contain a reactive fluid (0201), a drive device (0202) such as a rupture disk, a mechanical retaining element (0203) such as a nut and mechanically connected to a well drilling device such as an energy device (0220) with a hammer bolt (0204), a percussion initiator (0205), an intensifier ( 0206) and a detonating cord (0207). A detailed view of the well drilling tool (0210) is illustrated in FIGURE 1. The complete tool (0200) can be piped into the cladding chain as an integral part of the chain and can be placed where the operation of the tool is desired or the tool can be deployed in the desired location with TCP, CT or a wired line. Well drilling may be cemented or not. The fluid in the reservoir (0211) is maintained in an initial position by the drive device (0202), such as a rupture disk. The tool mandrel is carved to accept the drive device (0202) (such as rupture discs) that finally controls the flow of the reactive fluid (0201). The fluid reservoir (0211) can also be installed inside a fluid retention body (0208). The fluid retention body (0208) can be operatively connected to a body (0209) of the energy device (0220). In one embodiment, the rated pressure of the drive device may vary from 35.15 kg / cm.<sup>2</sup> at 1054.6 kg / cm<sup>2</sup> (from 500 lb / pg<sup>2</sup> at 15000 lb / pg<sup>2</sup>).
The reservoir (0211) can be in fluid communication with the mechanical retention element through the drive device (0202). Alternatively, the reactive fluid may be directly in fluid communication with the mechanical retention element through the drive device (0202) without a reservoir. For example, the mechanical retention element may not initially be in fluid communication with any fluid. When the pressure in the well drilling lining increases to drive the drive device, the well drilling fluids can enter and react with the mechanical retention element. It should be borne in mind that the reservoir for containing a reactive fluid cannot be interpreted as a limitation. A pressure port (0213) can be connected to another end of the tank through another actuator (0212). The reservoir (0211) can be a retention tank that can be placed inside a fluid retention body (0208) of a well liner. The volume of the tank can vary from 25 ml to 5 liters. The material of the reservoir can be selected so that the reactive fluid inside the reservoir does not react with the reservoir material and therefore does not corrode or erode the reservoir (0211). According to a preferred exemplary embodiment, the material of the reservoir can be selected from a group comprising: metal, ceramic, plastic, degradable, long-term degradable, glass, composite material or combinations thereof. The reservoir can also be pressurized so that there is sufficient flow of the reactive fluid to the retention element. The drive device (0202) may be a reverse action rupture disk that blocks fluid communication between the reactive fluid and the retention element. The drive device (0212) breaks or drives when a pressure in the borehole drilling through the pressure hole (0213) exceeds a rated pressure of the drive device (0212). After the rupture of the drive device (0212), the pressure acting through the pressure port (0213) can act on the fluid which also acts on the drive device (0202). When the pressure of the fluid acting on the drive device (0202) exceeds a rated pressure of the drive device (0202), the reactive fluid (0201) flows through and enters a chamber and makes contact with the retention element (0203). According to another preferred exemplary embodiment, the drive device is an electronic switch that is actuated by a signal from a device that stores stored energy.
The pressure on the drive device (0202) can be increased to the pressure rated with reactive fluid pressure. The reactive fluid (0201) is configured to react with the mechanical retention element (0203) at a temperature that is expected to be in the borehole. According to a preferred exemplary embodiment, a change of physical property in the retention element may occur at a predetermined temperature that is expected to be in the well borehole liner. According to an additional preferred exemplary embodiment the predetermined temperature varies from 25 ° C - 250 ° C. The mechanical retention element (0203) can be a nut, a shear pin or a retention device that degrades as the reaction takes place.

CONCLUSION
A tool and a method of delaying a well drilling lining have been disclosed. The tool / method includes a mechanical retention element, a reservoir for containing a reactive fluid, a drive device and a well drilling device. When an energy stored in the well drilling device is applied, the drive device is driven and makes it possible for the reactive fluid in the reservoir to come into contact with the mechanical retention element. While the mechanical retention element is subjected to a change in its shape due to a chemical reaction, a stored energy applied in the well drilling device is delayed by a predetermined delay. The amount of the predetermined delay is defined by factors that include the reaction fluids, the concentration of the reactive fluids, the geometry and the size of the mechanical retention element.
Although a preferred embodiment of the present invention has been illustrated in the associated drawings and has been set forth in the Detailed Description above, it will be understood that the invention is not limited to the modalities disclosed, but that it has the capability of numerous rearrangements, modifications and substitutions without departing from the spirit of the invention as set forth and defined by the following claims.
