Description

Technical Field

[0001] The present invention relates to the technical field of deployment and recovery systems, in particular to a deployment and recovery system and method for a subsea blowout preventer group of a surface blowout preventer combined with a subsea blowout preventer group. Background Art

[0002] Subsea oil is one of the mineral resources buried in sedimentary rocks and bedrock below the bottom of the ocean. The production process of subsea oil is generally divided into two stages: exploration and exploitation. The subsea oil exploitation process includes drilling production wells, oil and gas production, concentration, processing, storage and transportation. Subsea blowout preventers are needed in the specific exploitation process to prevent large amounts of oil from gushing out during the oil exploitation process. BOP groups can be divided into two categories according to their operating positions: surface BOP groups arranged above the water surface and subsea BOP groups arranged underwater. The two operating positions bring about great differences in the composition of the deployment and recovery systems.

[0003] Existing deployment and recovery systems are all installed on both sides of the moonpool through brackets, so that workers can deploy the excavation tools to the appropriate installation position at the bottom of the moonpool. However, the existing deployment and recovery devices require multiple adjustments to the position of the hook to reach directly above the installation position, which affects the installation efficiency. In addition, when lifting the surface blowout preventer, the hook collides with the lifting equipment, thereby affecting the stability of the surface blowout preventer. Therefore, a deployment and recovery system and method for a subsea blowout preventer group that combines a surface blowout preventer with a subsea blowout preventer group is needed to solve the existing shortcomings.

[0017] A method for deploying and recovering a surface blowout preventer combined with a subsea blowout preventer group comprises the following steps:

[0018] S1. First, install the support frame on both sides of the moon pool, and then use two clamps to clamp and fix the two ends of the surface blowout preventer so that it can move with the towing rope.

[0019] S2. Then, servo motor 2 is used to drive the reel rod to rotate at the bottom end of the suspension plate, so that the traction rope drives the surface blowout preventer to move upward. The traction rope is kept moving vertically upward by the movement inside the support rod until the clamp contacts the baffle, pushing the buffer rod to move upward and compressing the buffer spring to shorten it, thereby reducing the impact force on the support rod and maintaining the stability of the surface blowout preventer.

[0020] S3. Then, servo motor 1 is used to drive the threaded rod to rotate, driving the rack to move inside the support frame, thereby driving the gear to rotate inside the support frame, and then driving the drive rod to rotate with the center of the ring frame as the axis, thereby driving the hanging plate to move in an upward arc.

[0021] S4. The driving rod is rotated to drive the cone wheel 1 to rotate synchronously. The cone wheel 2 is used to make the cone wheel 3 rotate in the opposite direction. The transmission wheel 1 and the cone wheel 3 are rotated synchronously through the rotating shaft. Then, the transmission wheel 2 is driven to rotate under the action of the belt, so that the rotation direction of the hanging plate is opposite to the rotation direction of the driving rod, thereby always keeping the hanging plate in a horizontal position during the rotation of the driving rod.

[0022] S5. Use the counterweight to prevent the hanging plate from tilting, and then use the servo motor 2 again to lower the square traction rope until the surface blowout preventer is sent to the appropriate installation position.

[0023] Beneficial effects:

[0024] Compared with the existing technology, the deployment and recovery system and method of the surface blowout preventer combined with the subsea blowout preventer group have the following beneficial effects:

[0025] First, the present invention uses a drive mechanism that uses a servo motor to drive the threaded rod to rotate, driving the rack to move inside the support frame, thereby driving the gear to rotate inside the support frame, and then driving the drive rod to rotate around the center of the ring frame, thereby driving the hanging plate to move in an upward arc until the hanging plate rises to the highest point of the ring frame, facilitating the transportation of the surface blowout preventer from the periphery of the moonpool to directly above the moonpool, thereby facilitating the lowering of the surface blowout preventer to a suitable installation position.

[0026] Second, the present invention sets a reverse mechanism, which drives the cone wheel 1 to rotate synchronously during the rotation of the driving rod, and the cone wheel 3 rotates in the opposite direction through the action of the cone wheel 2. The transmission wheel 1 and the cone wheel 3 rotate synchronously through the rotating shaft. Then, under the action of the belt, the transmission wheel 2 is driven to rotate, so that the rotation direction of the hanging plate is opposite to the rotation direction of the driving rod, thereby always keeping the hanging plate in a horizontal position during the rotation of the driving rod, and facilitating the movement of the surface blowout preventer.

[0027] 3. The present invention provides a buffer mechanism and utilizes servo motor 2 to drive the reel rod to rotate at the bottom end of the suspension plate, thereby causing the traction rope to drive the surface blowout preventer to move upward. The movement of the traction rope inside the support rod is utilized to maintain the traction rope in vertical upward movement until the clamper contacts the baffle, pushing the buffer rod to move upward and compressing the buffer spring to shorten, thereby reducing the impact force on the support rod and maintaining the stability of the surface blowout preventer, which is conducive to the surface blowout preventer moving with the suspension plate.

8. A recovery method based on the deployment and recovery system of the surface blowout preventer combined with the subsea blowout preventer group according to any one of claims 1 to 7, characterized in that: The steps include: S1. First, the support frame (1) is installed on both sides of the moon pool, and then two clamps (8) are used to clamp and fix the two ends of the surface blowout preventer respectively so that it can move with the traction rope (7); S2. Then, the servo motor 2 (15) is used to drive the reeling rod (14) to rotate at the bottom end of the suspension plate (3), so that the traction rope (7) drives the surface blowout preventer to move upward. The traction rope (7) is used to move vertically upward by the movement of the traction rope (7) inside the support rod (6) until the clamp (8) contacts the baffle (901), pushing the buffer rod (903) to move upward and compressing the buffer spring (902) to shorten it, thereby reducing the impact force on the support rod (6) and maintaining the stability of the surface blowout preventer. S3. Then, the servo motor 1 (401) is used to drive the threaded rod (404) to rotate, driving the rack (403) to move inside the support frame (1), thereby driving the gear (402) to rotate inside the support frame (1), and then driving the driving rod (405) to rotate with the center of the ring frame (2) as the axis, thereby driving the hanging plate (3) to move in an upward arc. On the opposite side of the front end of the driving rod (405), the guide column (11) moves along the guide groove (10) to assist the driving rod (405) in rotating until the hanging plate (3) rises to the highest point of the ring frame (2) and is located in the middle of the support frame (1); S4. The driving rod (405) is rotated to drive the cone wheel 1 (501) to rotate synchronously. The cone wheel 3 (503) is rotated in the opposite direction by the action of the cone wheel 2 (502). The transmission wheel 1 (504) and the cone wheel 3 (503) are rotated synchronously by the rotating shaft. Then, the transmission wheel 2 (505) is driven to rotate under the action of the belt (506), so that the rotation direction of the hanging plate (3) is opposite to the rotation direction of the driving rod (405), thereby always keeping the hanging plate (3) in a horizontal position during the rotation of the driving rod (405); S5. Use the counterweight (16) to prevent the hanging plate (3) from tilting, and then use the servo motor 2 (15) again to lower the traction rope (7) until the surface blowout preventer is sent to a suitable installation position.
