Abstract
Description
Technical Field
[0001] This application belongs to the field of oil and gas field development technology, especially the field of well control technology, and specifically relates to a surface blowout preventer control device with emergency delay linkage function. Background Technology
[0002] In existing technology, the driller's control console (auxiliary control console) requires two-hand operation. For example, the left hand must continuously operate the main gas valve to connect the gas supply, while the right hand operates the gas transfer valves that need to be controlled to activate the corresponding control objects on the remote platform. During drilling, if a blowout or kick occurs and a hard shut-in is required, the control system needs to close the ring valve first, then the partial shut-in valve, and finally open the blowout valve, i.e., operate three control objects sequentially. In an emergency, this series of actions may lead to errors due to panic, and may also delay the driller's escape time. Summary of the Invention

This device does not affect the control of conventional pipelines, and both can be operated independently.

[0049] The surface blowout preventer (BOP) control device (hereinafter referred to as the control device) is an important safety equipment for preventing blowouts in oil and gas drilling. The control device mainly consists of a remote control console, a driller's control console, an auxiliary control console, and an air cable. The driller's control console is usually installed on the drill platform, while the auxiliary control console is located in the team leader's room. Both are remotely controlled via an air cable. During drilling, if a blowout or kick occurs, requiring a hard shut-in, the control system needs to close the ring valve first, then the partial seal, and finally open the blowout valve—that is, operate three control objects sequentially. In an emergency, this series of actions may lead to errors due to panic, and may also delay the driller's escape time. Therefore, an emergency delay linkage device needs to be designed, which allows the sequential switching of the three control objects by pressing two buttons simultaneously. This device does not affect the control of conventional pipelines, and the two can be operated independently. Based on this and to solve at least some of the technical problems in the background section of this application, embodiments of the present invention provide a specific implementation of a surface blowout preventer control device with an emergency delay linkage function.

[0083] To further illustrate the solution, in one specific embodiment, the present invention also provides a specific embodiment of a ground blowout preventer control device with emergency delay linkage function. The ground blowout preventer control device with emergency delay linkage function includes:
[0084] Three-position four-way hydraulic rotary valve (101, 102, 103), three-position four-way pneumatic rotary valve (201, 202, 203; 301, 302, 303), two-position two-way pneumatic rotary valve (90, 100), cylinder (401, 402, 403; 501, 502, 503; 601, 602, 603), air source treatment element (70, 80), two-position three-way pneumatic control valve (1101, 1102; 1201, 1202), two-position three-way single pneumatic directional valve (20 12, 2022, 2032; 3012, 3022, 3032), exhaust valves (1103, 2010, 2020, 2030; 1203, 3010, 3020, 3030), shuttle valves (2011, 2021, 2031; 3011, 3021, 3031; 130, 140, 150, 160, 170, 180), two-position three-way pneumatic delay directional valves (1104, 1105; 1204, 1205, see structure). Figure 7 (1301, 1302, 1303, 1304; 1501, 1502, 1503, 1504; 1801, 1802, 1803, 1804). Their connection relationships are as follows:
[0085] One connection is the standard one: the outlet of the air source processing element (70, 80) is connected to the inlet of the two-position two-way air rotary valve (90, 100) on the driller's control console or auxiliary control console. The outlet of this rotary valve is then connected to the inlet of the annular, semi-sealed, and release-type three-position four-way air rotary valve (201, 202, 203; 301, 302, 303). The outlets of the three three-position four-way air rotary valves are divided into two paths: one path is connected to one end of the cylinder (501, 502, 503; 601, 602, 603), and the other path is connected to the shuttle valve (2011, 2021, 2031; 3011, 3021, 3031). 31) The two are connected to the inlet and outlet of the annular, semi-sealed, and release spray, i.e., three-position four-way hydraulic rotary valve cylinders (401, 402, 403) on the remote console via shuttle valves (130, 140, 150, 160, 170, 180); the other end of the cylinders (501, 502, 503; 601, 602, 603) is connected to the exhaust valves (2010, 2020, 2030; 3010, 3020, 3030) via two-position three-way single pneumatic control directional valves (2012, 2022, 2032; 3012, 3022, 3032).
[0086] The other path is an emergency delay linkage connection: the outlet of the air source treatment element (70, 80) is connected to the two-position three-way pneumatic control valve (1101, 1102; 1201, 1202) and exhaust valve (1103, 1203) on the driller's control console or auxiliary control console. Its outlet is divided into two paths. The first path has one branch connected to shuttle valve 130 via shuttle valve (2011, 3011), and the second branch connected to cylinder (501, 601) via exhaust valve (2010, 3010) and two-position three-way single-pneumatic directional valve (2012, 3012). The outlet of the second path is connected to the two-position three-way pneumatic delay directional valve (1104, 1203). 4) Its outlet is divided into two paths. The first path has one branch connected to shuttle valve 150 via shuttle valve (2021, 3021), and the second branch is connected to cylinder (502, 602) via exhaust valve (2020, 3020) and two-position three-way single pneumatic control directional valve (2022, 3022). The outlet of the second path is connected to two-position three-way pneumatic delay directional valve (1105, 1205). The first branch is connected to shuttle valve 180 via shuttle valve (2031, 3031), and the second branch is connected to cylinder (503, 603) via exhaust valve (2030, 3030) and two-position three-way single pneumatic control directional valve (2032, 3032).
[0087] The above-mentioned ground blowout preventer control device with emergency delay linkage function can perform the following operations:
[0088] 1. When emergency linkage is required, press the two-position three-way pneumatic control valves (1101, 1102; 1201, 1202) simultaneously with both hands on the driller's control console or auxiliary control console. Compressed air will then be split into two paths through the exhaust valves (1103, 1203). One path passes through the shuttle valves (2011, 3011, 130) and enters the rod chamber of cylinder 401 (annular cylinder) on the remote control console, pushing the handle to move the annular rotary valve 101 to the "closed" position. At the same time, the gas passes through the exhaust valves (2010, 3010) and the two-position three-way single-pneumatic directional valves (2012, 3012) into the rodless chamber of cylinder (501, 601), which is equipped with a nameplate to indicate the "closed" position. The other chamber of cylinder (401, 501, 601) is discharged through the annular rotary valve (201, 301). Another path, after a 30-second delay via a two-position three-way pneumatic delay directional valve (1104, 1204), splits into two paths. The first path enters the rod chamber of the semi-sealed cylinder 402 on the remote control console through shuttle valves (2021, 3021, 150), pushing the handle to move, thereby turning the semi-sealed rotary valve 102 to the "closed" position. At the same time, the gas enters the rodless chamber of cylinders (502, 602) through exhaust valves (2020, 3020) and two-position three-way single pneumatic directional valves (2022, 3022). These cylinders are equipped with nameplates to indicate the "closed" position. The gas in the other chamber of cylinders (402, 502, 602) is discharged through the semi-sealed rotary valves (202, 302). The second path, after a 30-second delay via a two-position three-way pneumatic delay directional valve (1105, 1205), enters the rodless chamber of the release cylinder 403 on the remote control console through shuttle valves (2031, 3031, 180), pushing the handle to move and thus turning the release valve 103 to the "open" position. Simultaneously, gas enters the rod chamber of cylinders (503, 603) through exhaust valves (2030, 3030) and two-position three-way single pneumatic directional valves (2032, 3032). These cylinders are equipped with nameplates to indicate the "open" position. The gas in the other chamber of cylinders (403, 503, 603) is discharged through the release valves (203, 303).
[0089] 2. The emergency operating air circuit can be disconnected on the remote control console by closing the shut-off valves (1301, 1304; 1501, 1504; 1801, 1804) connected to the driller's control console (auxiliary control console) and opening the shut-off valves (1302, 1303; 1502, 1503; 1802, 1803), thereby venting the compressed air in the cylinder and enabling manual operation of the annular, semi-sealing rotary valve and the blow-out valve at the remote control console.
[0090] According to the requirements of the floating blowout preventer control system, the semi-sealed blowout preventer should be able to close within 30 seconds. The closing time of the annular blowout preventer with a nominal diameter of less than 476.25 mm (18.3 / 4 in) should not exceed 30 seconds. The response time (open or close) of the blowout release valve should not exceed the minimum value among the known gate blowout preventer response times. The delay time of the two-position three-way pneumatic delay reversing valve on the linkage pipeline is set to 30 seconds.
[0091] When emergency operation is required, simultaneously press the two-position three-way pneumatic control valve with both hands on the driller's control console or auxiliary control console. Compressed air will enter the annular rotary valve on the remote control console, turning it to the "closed" position, and the annular cylinder on the driller's control console or auxiliary control console will display the "closed" position. After 30 seconds, compressed air will enter the semi-sealed rotary valve on the remote control console, turning it to the "closed" position, and the semi-sealed cylinder on the driller's control console or auxiliary control console will display the "closed" position. After another 30 seconds, compressed air will enter the vent valve on the remote control console, turning it to the "open" position, and the vent cylinder on the driller's control console or auxiliary control console will display the "open" position. By closing the shut-off valve connected to the driller's control console or auxiliary control console on the remote platform and opening the exhaust shut-off valve, the emergency operation air circuit is disconnected on the remote control console, and the compressed air in the cylinder is released, allowing manual operation of the annular, semi-sealed rotary valve, and vent valve at the remote control console.
[0092] As described above, the specific embodiments of the present invention provide a ground blowout preventer control device with emergency delay linkage function, including: a driller's control console, an auxiliary control console, and a remote control console; wherein: the driller's control console includes: a first air source processing element, three cylinders each connected to a three-position four-way pneumatic rotary valve and a two-position three-way single-pneumatic directional valve, and two three-way pneumatic delay directional valves; wherein, the three cylinders of the driller's control console are connected through the two three-way pneumatic delay directional valves of the driller's control console; the auxiliary control console includes: a second air source processing element, three cylinders each connected to a three-position four-way pneumatic rotary valve...

[0093] The surface blowout preventer control device with emergency delay linkage function provided by this invention can be used in emergency situations. By simultaneously pressing two buttons on the driller's control console (auxiliary control console), the sequential operation of first closing the ring valve, then closing the half-sealed valve, and finally opening the blowout valve can be achieved. This solves the problem of potential misoperation caused by a large number of control valves and multiple steps, saves driller's escape time, and improves the accuracy and safety of operation.
