Method and apparatus for dropping a pump down plug or ball.
Abstract
An improved method and apparatus for dropping a ball, plug or dart during oil or gas well operations (eg, cementing operations) employs a specially configured tool body assembly having valve members (eg, valves Kelly) and valve members that hold the plugs, balls or darts to be dropped. A transmitter (or transceiver) provides the ability to generate a wireless signal that is received by the receivers (or transceivers) in the body assembly of the tool. Each receiver (or transceiver) controls an electrical actuator that engages a valve member. Wireless signals can be used to open or close a selected valve member.

In Figures 1A-C and 6, the body 171 ti<sub>Q</sub>n<sub>OR</sub> , m<sub>g</sub> upper end portion 172 with a connector 173 and a lower end portion 174 with a connector 175. The connectors 173, 175 may be threaded connectors. Tool body 171 may be sized and / or configured for use with a drillstring or enclosure. An upper crossbar tool 176 can be used to connect the tool body 171 with a top drive. Similarly, a lower stud tool 197 can be used to connect to a drillstring or enclosure. The upper crossbar tool 176 connects the Kelly valve 177 in a threaded connection 178. Pivot 179 (eg, a torque through pivot - See Figures 1A and 2) connects to an upper Kelly valve 177 in a connection 180 (eg, a threaded connection). Alternatively, a hub 188 can be positioned between valve 177 Kelly and pivot 179. Pivot 179 connects to a lower Kelly valve 185 in a connection 184 which may be a threaded connection. A hub 188 may be positioned between pivot 179 and Kelly valve 185.
Pivot 179 is commercially available and provides the rotating and non-rotating portions. A torque arm 181 supports the rotating and non-rotating portion of the pivot 179 to prevent rotation while the portions of the tool body 171 above the connection 180 and below the connection 184 rotate.

The pivot 179 has a hole 2T9 that allows communication with the hole 250 of the tool chord assembly 171, as noted in US Patent No. 7,607,481; No. 7,841,410 and / or No. 7,918,278 and Figures 1A-C, 2, 6 and 22-24. A cement pump 220 pumps the cement through a flow line or hose 221 to valve 183, such as low torque valve 183. Inlet 192 can be adjusted with a reducer 222 and a low torque valve 183 that can be opened or closed to allow inflow of a selected cementitious mix (see Figures 1A, 1B and 6).
Upper hub 188 fits between Kelly valve 185 and cement head 187. A threaded connection or other connection in 186 connects hub 188 to Kelly valve 185. A threaded connection or other connection in the 189 connects the hub 188 to the cement head 187. The cementing head 187 can be any type of plug dropping apparatus shown and described. In Figures 1A-1C and 6, plug drop head 187 employs two (2) plug chambers 190, 192. The plug chamber 190 is an upper plug chamber. Plug chamber 192 is a lower plug chamber. A connection 191 (eg threaded) joins the chambers 190, 192.
Connection 193 (eg threaded) connects bottom plug chamber 192 to hub 194. Hub 194 may be a hub with a gauge 194. Hub 196 connects cross member 197 with a connection, such as connection 195 of thread. A stud 197 may be a lower stud with the enclosure (or pipe).

FROM THE FROPIFIMD 'NDUSTKjaI Transmitter 2 equipped with a number of 218 alternator switches, each switch operates a selected 201-206 electric actuator. These actuators 201-206 allow any valve or valve member 246 of the tool body 171 to be open or closed, they also allow the indicator tag 246 to be reset to an original or home position (refer to Figure 23) after it is has been disconnected or deflected by a plug or dropped ball (see Figure 24). More toggle switches or more actuators 201-206 will be required when there are more plug chambers 190, 192 or well control valves 177, 185.
A primary receiver 198 receives a signal from transmitter 210. Primary receiver 198 then sends a signal to a secondary receiver 199 or 200 that is located above and below pivot 179, respectively. Other transmitter and receiver configurations may be used. However, with the use of a primary receiver 198 at pivot 179, it can communicate with other "secondary" receivers 199, 200. Receivers 199 and 200 rotate with tool body 171 above (receiver 199) and below (receiver 200) pivot 179. This arrangement allows a receiver 199 or 200 to drive a controller that is also rotating, such as a actuator / controller 201 for valve 177 Kelly or controller 203 for valve 185 Kelly or controller 204 for valve member of top plug chamber 190 or controller
205 for the valve member of the lower plug chamber 192 or the
ΙΜΡΐίζίδ ^ controller 206 resetting industrial tag flag 246
Secondary receiver 199 operates electrical actuator 201 to selectively open or close Kelly valve 177. Secondary receiver 200 operates electrical actuator 203 to open or close Kelly valve 185. Any 201 or 203 actuator can open or close the 177 or 185 Kelly valve when under pressure up to 2200 psi (15,168 kPA) and in less than 15 seconds. This safety feature can be critical to well operation in the event of a dangerous explosion.
Other actuators operate other valves. Actuator 202 opens or closes low torque valve 183. Actuator 204 opens or closes valve member 279 of upper plug chamber 190 (eg, ball valve member or refer to plug chambers shown and described in EL Patents) A No. 7,607,481; No. 7,841,410 and / or No. 7,918,278). The actuator 205 opens or closes the valve member 280 of the lower plug chamber 192 (for example, the ball valve member or refer to the chambers shown and described in US Patents No. 7,607,481; No. 7,841,410 and / or No. 7,918,278 Actuator 206 resets tag cube 194 with a release indicator after the plug has been released. Such a release indicator is shown and described herein. Each electric actuator 201, 202, 203, 204, 205, 206 can be purchased as a wirelessly operated device from Parker (www.parker.com) for example.
Each actuator can be protected with a protective guard. Each receiver can be protected with a housing 209 or a guard (see Figure 9A). Transmitter 210 can be provided with security features such as an inteJrrjf¿l requires a key 215, a transparent emergency stop 217, a power switch 215, a ^ fcArniptnr / hntAn 914 and a status to signal whether or not the transmitter is in fact in wireless communication with the receivers or receiver modules 198, 199, 200. Transmitter 210 may be in the form of a housing or frame 212 having user handles 213.
In Figures 4-5, transmitter 210 may have features that require backup duplication in order to avoid inadvertent operation. Before the transmitter can be operated, the user must turn the emergency stop button 217 (eg, clockwise) and push and turn the key 215 to the "on" position. These two requirements accumulate redundancy and therefore security. In addition, the operation of any toggle switch 218 may also require the simultaneous depressing of button 214. Each toggle switch 218 may have an indicator lamp 223 (eg, LEDs) to indicate the correct position of the switch. Before starting operation, the user confirms that each lamp or LED correctly indicates the position of the alternator. Each receiver module 198, 199, 200 can be powered by a battery. The 224 indicator lamps on the transmitter (Figure 5, lower right corner) can be used to confirm the power level of each battery. The three illuminated lamps indicate full power, while one or two lamps indicate less than full power, and no illuminated lamp indicates that the battery is low or has no power.

Before operation is allowed the indTg ^ S ^^^^
INDUSTRIAL transparent should be illuminated, indicating that all lamps
LEDs have gone out, which means that all 218 alternators are in the neutral position.
A status lamp 225 (eg, LED) indicates to the user that the transmitter is in communication with receiver modules 198, 199, 200. The multiple alternator switches 218 may be dedicated to the operation of the ball or plug drop valve members. For example, the top row of toggle switches in Figure 5 may be designated to operate the ball, plug, or dart drop valve members. In Figure 5, these alternators are numbered 1, 2, 3, 4, 5. These alternators 1, 2, 3, 4, 5 must be operated in sequence (i.e., they always drop the smallest ball, dart, or plug first ). The other toggle switches (bottom row) can be used to operate 177, 185 Kelly valves, 183 low torque cement inlet control valve, indicator tag hub 194, or any other 'on demand valve member or device. ”. To operate the desired alternator 218, the user must also press button 214. Also, a "transparent" button 216 must be pressed to confirm that all indicator lamps or "LEDs are in the proper position.
Each of the actuators 201-206 may be equipped with position indicators to indicate whether the valve member is open or closed (eg, valve 177, 195 Kelly). Such an indicator may be in the form of a pointer rotating with the actuator-shaped arrow.

An actuator 201-206 may be equipped with a manual means (eg, handle or handwheel 226) to operate the actuator, as seen in Figure 7. Such a crank or handle 226 equipped with electric actuators are available for sale.
Figures 9B-aa show a typical arrangement for connecting an actuator 201-206 for a valve member such as a 177, 185 Kelly valve or a ball drop valve such as one of the plug or ball valves, as shown in US Patents No. 7,607,481; No. 7,841,410 and / or No. 7,918,278 and in Figure 6. In Figures 9A-B, a pair of clamping sections 227, 228 may be secured in a selected position in the tool body assembly 171 such as in a relief valve or a Kelly valve 177, 185. Bolted connections using a bolt 229 and a nut 230 can be used to hold the clamping sections 227, 228 with a safety valve 177, 185.
A hex socket 231 can be used to rotate the valve member of the Kelly valve, the safety valve, or the plug or ball drop valve as shown and described with respect to the embodiments of the US Pat. No. 7,607,481; No. 7,841,410 and / or No. 7,918,278. Valve 177, 185 provides an opening 231 (eg, hexagonal) that aligns with an opening 232 in clamp section 228 and opening 234 in adapter 233.
Adapter 233 can be defined by a bearing or bracket 234 that supports the adapter 208 shown in Figures 10 and 11. The openings 235 in the clamping section 228 align with the openings 236 of the adapter 233. The holders 238 can be use to secure adapter 233 with clamp section 228 as shown in Figure 9B. The fasteners 238 extend through the openings 236 of the adapter 233 and then into the internally threaded openings 235 of the fastening section 228. The fasteners 239 may form a threaded connection between the adapter 233 and the actuator 201205. The openings 237 and the adapter 233 are receptacles for fasteners 239. The fasteners 239 will form a threaded connection with an internal thread opening that is part of the actuator 201-206, such as the actuator 203 shown in Figure 9B.
Adapter 208 provides a cylindrical surface 240 and a hexagonal projection portion 241. The bushing 232 of the adapter 208 allows a connection to be formed with the cementing shaft of an actuator 201-205 (commercially available). Figures 22-30 show an arrangement for automatically resetting the indicator 246 such as the tag indicator. Clamping sections 243, 244 are provided to hold a housing or guard 259 for indicator cube 194. Bolt connections 245 can be used to hold fastening sections 243, 244 together. Tag indicator 246 is housed in a recess
273 of the indicator hub 194 as shown in Figures 22 and 25.
When the ball, dart or plug 58, 59, 76, 77 moves down in the
IMPIOS direction of arrow 274 in Figure 24, the ball pushes or rotates a lever 252 in the direction of arrow 275 at arrow 24. This rotation of lever 276 also rotates the indicator or indicator arm or label indicator 246 in the direction of arrow 276 in Figure 25. This position shift shown in solid lines in Figure 25 in the position shown in phantom lines in Figure 25 is visible to users and indicates that a ball or dart 58, 59, 76, 77 has been successfully thrown.
The present invention provides an automatic mechanism to remotely reset the tag indicator 246 to the position shown in solid lines in Figure 25. Thus, the tag indicator 246 can then be used again to indicate whether it has been dropped. successfully another plug or ball 58, 590, 76, 77. In order to rotate the indicator from the disconnected or dropped ball position shown in phantom lines in Figure 25 to the original position, an actuator 206 is provided. The actuator 206 is used to rotate an arrow 247 with which a lever 252. This reset position of lever 252 can be seen in Figures 22 and 23. Disconnected or activated position of lever arm 252 is seen in Figure 24.
The shaft 247 is supported on its end portions with bearings 248. A connection between the operator 206 and the shaft 247 is by means of a sleeve 249 having a hexagonal socket, a sleeve 253 forms a connection between the first link 256 and a second link 257. Sleeve 253 provides a sleeve hole 255 and traverses openings 263 that are receiving a pass.
