Description

Technical Field

[0001] This invention relates to the field of drilling choke pipe control technology, specifically to an embedded automatic control device for drilling choke pipe manifolds. Background Technology

[0002] With the continuous development of the oil and gas exploration and production industry, the requirements for well control safety management during drilling operations are constantly increasing. As a core supporting equipment for well control pressure relief and regulation, the control accuracy of the choke manifold directly determines the safety of drilling operations. Therefore, a high-precision drilling choke manifold embedded automatic control device is needed to automatically control the choke manifold.

[0003] However, existing control devices can only achieve single-sided clamping and limiting during use, making it difficult to achieve multi-directional synchronous locking with a single drive. The operation process is cumbersome, the clamping force is singular and the fixing effect is poor. During the operation of the equipment, the clamping is very easy to loosen, resulting in insufficient overall fixing stability. Summary of the Invention

[0004] The purpose of this invention is to provide an embedded automatic control device for drilling choke manifolds. By setting a fixing part, it solves the problems of existing control devices that can only achieve single-sided clamping and limiting during use, making it difficult to achieve multi-directional synchronous locking with a single drive, resulting in cumbersome operation procedures, single clamping force and poor fixing effect, and easy loosening of clamping during equipment operation, leading to insufficient overall fixing stability.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to an embedded automatic control device for a drilling choke manifold, comprising a support plate and a controller disposed on the top of the support plate, and further comprising: two fixing parts, both of which are disposed on the top of the support plate; a driving part mounted on the support plate; and a buffer part disposed on the bottom of the support plate. Each fixing part includes a transmission assembly disposed on the support plate; a fixing assembly is disposed on the transmission assembly; the transmission assembly includes a rectangular plate disposed on the top of the support plate, through which a transmission plate passes, and the transmission plate is slidably connected to the rectangular plate. Two inclined grooves are formed on the transmission plate, and two rectangular rings are fixedly connected to the outer wall of the rectangular plate, with rectangular rings slidably connected to the inner walls of the two rectangular rings. The slide bar has a transmission rod installed in each of the two inclined grooves. The two transmission rods are fixedly connected to the two rectangular slide bars respectively. An elastic element is installed on the rectangular plate. The two fixed parts are mirror images of each other. The two rectangular rings on each rectangular plate are located on the side of the two rectangular rings that are far apart from each other. The two inclined grooves are mirror images of each other. The elastic element includes two cylindrical rods fixedly connected to the side of the silicone fixing plate near the rectangular plate. The side of the two cylindrical rods away from the silicone fixing plate passes through the rectangular plate. The two cylindrical rods are slidably connected to the rectangular plate. The outer wall of the two cylindrical rods is fitted with a spring. The side of the two springs near the rectangular plate is fixedly connected to the rectangular plate. The side of the two springs away from the rectangular plate is fixedly connected to the silicone fixing plate. The two cylindrical rods are arranged in parallel.

[0006] Furthermore, the driving unit includes a driving assembly mounted on a support plate and a locking assembly disposed on the driving assembly.

[0007] Furthermore, the buffer section includes a base plate disposed at the bottom of the support plate, and a plurality of damping rods are fixedly connected to the top of the base plate. The top of each of the damping rods is fixedly connected to the bottom of the support plate, and a reset member is disposed on each of the damping rods. There are four damping rods, which are respectively located at the four corners of the base plate. The reset member includes a second spring sleeved on the outer wall of the damping rod. The top of the second spring is fixedly connected to the support plate, and the bottom of the second spring is fixedly connected to the base plate.

[0008] Furthermore, the fixing assembly includes a silicone fixing plate one fixedly connected to the side of the transmission plate away from the rectangular plate, and silicone fixing plates two fixedly connected to each of the two rectangular slide rods; the two silicone fixing plates two are located on the front and rear sides of the silicone fixing plate one, respectively, and are mirror images of each other.

[0009] Furthermore, the drive assembly includes a limiting groove formed on the top of the support plate, in which a sliding plate is slidably connected. The tops of the two sliding plates are respectively fixedly connected to two rectangular plates. The bottom of the support plate is fixedly connected to two square plates. A bidirectional threaded rod passes through the two square plates and is rotatably connected to the two square plates. The right side of the bidirectional threaded rod extends to the outside of the right-side square plate. The bidirectional threaded rod passes through the two sliding plates and is threadedly connected to the two sliding plates. A crank is fixedly connected to the outer wall of the bidirectional threaded rod. A protective component is provided on the bidirectional threaded rod. The two sliding plates are respectively located on the threads on both sides of the bidirectional threaded rod. The crank is located on the right side of the right-side square plate. The protective component includes several telescopic protective sleeves sleeved on the outer wall of the bidirectional threaded rod. The sides of the two telescopic protective sleeves located on the left and right sides that are close to each other are fixedly connected to the two sliding plates. The sides of the two telescopic protective sleeves located on the left and right sides that are far apart from each other are fixedly connected to the two square plates. Three telescopic protective sleeves are provided, and the left and right sides of the middle telescopic protective sleeve are fixedly connected to the two sliding plates.

[0010] Furthermore, the locking assembly includes a U-shaped ring sleeved on the outer wall of the bidirectional threaded rod.

Several elastic blocks are fixedly connected to the inner wall of the left side of the U-shaped ring. An extrusion member is provided on the U-shaped ring. There are six elastic blocks arranged in a circumferential array. The extrusion member includes an extrusion ring sleeved on the outer wall of the bidirectional threaded rod. The extrusion ring is threadedly connected to the U-shaped ring.

[0011] Furthermore, the controller in this device is a DK-3-GZ Guangji embedded control box. Its working principle relies on the built-in embedded motherboard to receive the working condition signal transmitted by the pressure sensing device at the drilling choke manifold in real time. It compares and calculates the real-time pressure value with the preset control standard, and outputs control commands based on the difference to drive the matching hydraulic actuator to adjust the opening and closing degree of the choke valve. The whole process forms a closed-loop control logic, thereby continuously stabilizing the downhole pressure and realizing unmanned automatic control of the choke manifold during drilling operations.

[0012] The present invention has the following beneficial effects: (1) By setting a fixing part, the rectangular plates move towards each other. The silicone fixing plate is driven by the transmission plate, cylindrical rod and spring to adhere to the left and right sides of the controller. The rectangular plates continuously feed and compress the spring to store energy. At the same time, the rectangular plates pull the rectangular slide rod with the help of the rectangular ring. The transmission rod slides along the inclined groove and drives the silicone fixing plate to press against the front and rear sides of the controller. Together with the silicone fixing plate, the controller is wrapped and clamped on all four sides. A single driving action can achieve multi-directional synchronous locking. The operation is simple, the fixing is reliable, and it is not easy to loosen after clamping. The overall fixing stability is greatly improved. (2) By setting up a drive unit, the controller is placed above the support plate during use. The crank handle is turned to drive the bidirectional threaded rod to rotate. The two slide plates slide towards each other by relying on the cooperation between the bidirectional threaded rod and the limiting slide groove. The rectangular plate moves closer to clamp the controller. The telescopic protective sleeve deforms with the displacement of the slide plate to protect the threaded part of the bidirectional threaded rod. After clamping, the extrusion ring is screwed on. The extrusion ring and the U-shaped ring are threaded together to squeeze the elastic block to fit against the outer wall of the bidirectional threaded rod and lock the threaded rod, preventing the threaded rod from rotating unexpectedly. It can continuously protect the threaded structure of the bidirectional threaded rod and reduce transmission failure caused by impurities and wear. It has a self-locking anti-reverse function. It is stable and not easy to loosen after long-term use, and the overall stability of the controller is improved. (3) By setting up a buffer section, when the controller vibrates during operation, the damping rod and spring set between the base plate and the support plate work together to absorb the vibration force generated by the controller, ensuring the smooth operation of the controller, effectively buffering and reducing the vibration generated by the operation of the equipment, reducing the adverse effects of vibration, reducing the probability of loosening and wear of parts, continuously maintaining the stable working state of the equipment, and extending the service life of the overall device.

Rotary connection: The right side of the bidirectional threaded rod 314 extends to the outside of the square plate 313 located on the right side. The bidirectional threaded rod 314 passes through two sliding plates 312 and is threadedly connected to the two sliding plates 312. A crank handle 315 is fixedly connected to the outer wall of the bidirectional threaded rod 314. A protective component is provided on the bidirectional threaded rod 314.

The crank handle 315 is located on the right side of the square plate 313 located on the right side. The protective component includes several telescopic protective sleeves 31 sleeved on the outer wall of the bidirectional threaded rod 314. 6. The two telescopic protective sleeves 316 located on the left and right sides, with their sides close to each other, are fixedly connected to the two sliding plates 312 respectively. The two telescopic protective sleeves 316 located on the left and right sides, with their sides far from each other, are fixedly connected to the two square plates 313 respectively. Three telescopic protective sleeves 316 are provided, and the left and right sides of the telescopic protective sleeve 316 located in the middle are fixedly connected to the two sliding plates 312 respectively. The locking assembly 32 includes a U-shaped ring 321 sleeved on the outer wall of the bidirectional threaded rod 314. The left side of the U-shaped ring 321 is fixedly connected to the square plate 313 located on the right side. Several elastic blocks 322 are fixedly connected to the inner left side of the U-shaped ring 321. An extrusion component is provided on the U-shaped ring 321. There are six elastic blocks 322 arranged in a circumferential array. The extrusion component includes an extrusion ring 323 sleeved on the outer wall of the bidirectional threaded rod 314. The extrusion ring 323 is threadedly connected to the U-shaped ring 321. By setting the drive unit 3, the thread structure of the bidirectional threaded rod 314 can be continuously protected, reducing transmission failure caused by impurity wear. It has a self-locking anti-reverse function, and the clamping is stable and not easy to loosen during long-term use, thus improving the overall fixation reliability of the controller 112.

[0021] The buffer section 4 includes a base plate 411 disposed at the bottom of the support plate 111. Several damping rods 412 are fixedly connected to the top of the base plate 411. The top of each damping rod 412 is fixedly connected to the bottom of the support plate 111. Each damping rod 412 is provided with a reset component. There are four damping rods 412, located at the four corners of the base plate 411. The reset component includes a second spring 413 sleeved on the outer wall of the damping rod 412. The top of the second spring 413 is fixedly connected to the support plate 111, and the bottom of the second spring 413 is fixedly connected to the base plate 411. By setting up the buffer section 4, the vibration generated by the operation of the equipment is effectively buffered and reduced, the adverse effects of vibration are mitigated, the probability of loosening and wear of parts is reduced, the stable working state of the equipment is maintained, and the service life of the overall device is extended.

[0022] In use, the controller 112 is placed on top of the support plate 111, and the crank handle 315 is turned. The crank handle 315 drives the bidirectional threaded rod 314 to rotate. Under the parallel cooperation of the bidirectional threaded rod 314 and the limiting slide groove 311, the bidirectional threaded rod 314 drives the two slide plates 312 to slide in the limiting slide groove 311 and move closer to each other. During this process, the three telescopic protective sleeves 316 deform with the movement of the two slide plates 312 and protect the thread groove of the bidirectional threaded rod 314. At this time, the two slide plates 312 respectively drive the two rectangular plates 211 to move closer to each other. When the two rectangular plates 211 approach each other, they drive the two silicone fixing plates 221 to approach each other via corresponding transmission plates 212, two cylindrical rods 217, and two springs 218, respectively, and they contact the left and right sides of the controller 112. Then, the two rectangular plates 211 continue to approach each other, sliding on the corresponding transmission plates 212 and two cylindrical rods 217, and compressing the two springs 218, causing them to deform and generate elastic force. At this time, the rectangular plates 211 drive the two rectangular sliding rods 215 to move via two rectangular rings 214. The slide rod 215 drives the two transmission rods 216 to slide in the corresponding inclined grooves 213. Under the action of the two inclined grooves 213, the two transmission rods 216 are pushed closer to each other. The two transmission rods 216 drive the two rectangular slide rods 215 to slide in the two rectangular rings 214 and move closer to each other. The two rectangular slide rods 215 drive the corresponding silicone fixing plates 222 to fix to the front and rear sides of the controller 112, and fix to the left and right sides of the two silicone fixing plates 221. The controller 112 is wrapped and fixed in a multi-directional way on the left, right, front and rear sides, thereby improving the stability of the controller 112. After fixing, rotate the compression ring 323. Since the compression ring 323 is threadedly connected to the U-shaped ring 321, the compression ring 323 moves into the U-shaped ring 321 and compresses the six elastic blocks 322, causing the six elastic blocks 322 to deform and move closer to the outer wall of the bidirectional threaded rod 314, thereby fixing the bidirectional threaded rod 314 and preventing the bidirectional threaded rod 314 from accidentally reversing under the action of external factors, which would affect the stability of fixing the controller 112. The controller 112 is started. The controller 112 receives the working condition signal transmitted by the pressure sensing device at the drilling choke manifold in real time by relying on the built-in embedded motherboard. It compares and calculates the real-time pressure value with the preset control standard, and outputs control commands based on the difference to drive the matching hydraulic actuator to adjust the opening and closing degree of the choke valve. The whole process forms a closed-loop control logic, thereby continuously stabilizing the downhole pressure and realizing unmanned automatic control of the choke manifold during drilling operations. During operation, the controller 112 is prone to vibration. At this time, the vibration force generated by the controller 112 is absorbed by the four damping rods 412 and the four springs 413 between the base plate 411 and the support plate 111, thereby improving the stability of the controller 112 operation.
