Problems solved by technology

The blowout preventer plays a vital role in the operation, so the blowout preventer needs to be easy to operate and have good sealing effect. The existing blowout preventer includes hydraulic blowout preventer and ring blowout preventer. When using Both need an external air pump, and use external power to drive the blowout preventer to play a sealing role. The equipment cannot complete the work alone, and the operation is not convenient enough, and the air pump connection has high requirements for sealing.

Embodiment 1

[0029] Such as Figure 1-7 As shown, a blowout unit includes a housing 1, a fixing plate 15 disposed on both sides of the housing 1 and a first equipment case 2 disposed above the fixing plate 15, and the first equipment box 2 is two. The group, respectively, sides of the housing 1, and the fixing plate 15 is used to secure the blowout unit to the wellhead, so that the blowout unit can act as a sealing of the oil well; the casing 1 is provided with a first through hole 11 The oil pipe can be inserted into the oil well from the first through hole; the first equipment case 2 is provided with a sealing assembly and a driving member for driving the sealing assembly; the first equipment box 2 The support seat 16 is provided at the bottom; the support seat 16 is provided as a triangular structure, and the first equipment box is fixed to the sidewall of the housing by the principle of triangular stability; the sealing assembly includes a sealing block 23, with the sealing block 23. The fi...

Embodiment 2

[0040] Such as Figure 8-10 As shown, the difference from the first embodiment is that the fixing plate 15 is provided with a fixture, the fixing device to be detachably connected to the fixing plate 15; a fixed device is fixed, an increase The fixing effect of the anti-blower enables the blowout unit to be more stable in the wellhead, which acts as a well preventive well-fitting effect; through the detachable connection of the fixture and the fixed plate, convenient to repair and maintenance of the fixing device, extend the fixed The service life of the device.

[0041] The fixture includes a second equipment tank 4 disposed on the fixing plate 15, a hydraulic cylinder 41 disposed within the second equipment tank 4, a rotary electric machine 44, a hydraulic cylinder 41 piston rod, and The positioning drill bit 45 is provided on the output shaft of the rotating motor 44; the piston rod of the hydraulic cylinder is inserted into the second device box, and the rotary electric machin...

Embodiment 3

[0045] Such as Figure 11-12 As shown, the difference between the present embodiment and the first embodiment is that the inner wall of the first through hole 11 is also provided with a fixed assembly; the oil pipe inserted into the blower inserted into the blower is fixed by a fixed component to avoid the oil pipe in oil. Generating vibration, affecting the connection effect of the oil pipe and the anti-blower, enhance the sealing of the anti-sprayer, and avoids the occurrence of blowout accidents.

[0046] The fixing assembly includes a second mounting plate 5 disposed on the inner wall of the first through hole 11, a connection spring 54 disposed on the second mounting plate 5 and a fastening that is secluded on the connection spring 54. The plate 51; the fixing assembly is two groups, respectively, on both sides of the inner wall of the first through hole, and the oil pipe is inserted into the first via hole, and the oil pipe is placed between the left and right fastening plate...

Abstract

The present invention discloses a blowout preventer. The blowout preventer comprises a housing, fixed plates arranged at two sides of the housing and first device boxes arranged at the upper portionsof the fixed plates, the housing is internally provided with a first through hole, the first device boxes are internally provided with seal modules and drive parts configured to drive movement of theseal modules, the bottom portions of the first device boxes are provided with support bases; each seal module comprises one seal block, one connection rod fixedly connected with the seal block and onefirst push plate arranged at one end of the first connection rod; the housing is internally provided with a first movable cavity, the first connection rod penetrates the internal portion of the firstmovable cavity, and the seal blocks are arranged in the first through hole; and the first movable cavity is internally provided with a leakage-proof module. The drive parts in the device cavity drivethe seal modules to form a seal effect on the first through hole, the seal work of the blowout preventer can be completed through power itself to allow the blowout preventer to be more easily operated; and through mutual cooperation of the leakage-proof module and the seal modules, the seal effect of the blowout preventer is improved, and the generation of the blowout accident is avoided.

Description

Technical field [0001] The present invention belongs to the technical field of leakage equipment, in particular, to a blowout counter. Background technique [0002] The anti-sprayer is used to close the wellhead in the process of testing oil, repair, completion, etc., preventing the blowout accident, combining the full sealing and semi-sealing two functions, is a safety seal well port device for preventing blowout in the fields of oil fields. . The anti-sprayer plays a vital role in the operation, so it is necessary to have good operations and sealing effects on the anti-blower, and the existing anti-sprayer has hydraulic blowout and annular anti-sprayer. Extraway is required, and the external power is driven to drive the bloating force. The equipment cannot be done separately. It is not convenient to operate, and the sealing requirements of the air pump connection are high. Inventive content [0003] In order to overcome the shortcomings of the prior art, the present invention ...
