Problems solved by technology

The blowout preventer is generally placed on the head of the oil well, and the oil delivery pipe needs to be inserted into the blowout preventer before being inserted into the oil well. When the oil delivery pipe is delivering oil, the pipe will vibrate to a certain extent, which will affect the connection effect between the oil delivery pipe and the blowout preventer, and reduce the The sealing effect of the injector on the wellhead is easy to cause blowout accidents

Embodiment 1

[0027] Such as Figure 1-7 As shown, a blowout preventer that is easy to fix the oil delivery pipe includes a casing 1, a fixing plate 15 arranged on both sides of the casing 1, and a first equipment box 2 arranged above the fixing plate 15. An equipment box 2 consists of two groups, which are fixedly connected to both sides of the housing 1 respectively. The fixing plate 15 is used to fix the blowout preventer at the wellhead so that the blowout preventer can seal the oil well; There is a first through hole 11, and the oil delivery pipe can be inserted into the oil well from the first through hole to perform oil pumping work; the first equipment box 2 is provided with a sealing assembly and a driving member for driving the sealing assembly to move; The bottom of the first equipment box 2 is provided with a support base 16; the support base 16 is set as a triangular structure, and the first equipment box is fixed on the side wall of the housing by using the principle of triang...

Embodiment 2

[0039] Such as Figure 8-10 As shown, the difference between this embodiment and Embodiment 1 is that: the fixing plate 15 is provided with a fixing device, and the fixing device is detachably connected with the fixing plate 15; the blowout preventer is fixed by the fixing device, increasing The fixing effect of the blowout preventer enables the blowout preventer to be fixed more stably at the wellhead and has a good blowout prevention effect; through the detachable connection between the fixing device and the fixing plate, the fixing device can be easily repaired and maintained, and the fixing time can be extended. The service life of the device.

[0040] Described fixing device comprises the second equipment box 4 that is located on described fixed plate 15, is located at the hydraulic cylinder 41 in described second equipment box 4, is located at the rotating motor 44 on the piston rod of described hydraulic cylinder 41 and The positioning drill bit 45 arranged on the outp...

Embodiment 3

[0044] Such as Figure 11-12 As shown, the difference between this embodiment and Embodiment 1 is that a fixing assembly is also provided on the inner wall of the first through hole 11; the oil delivery pipe inserted into the blowout preventer is fixed by the fixing assembly, so as to prevent the oil delivery pipe from The vibration will affect the connection effect between the oil pipeline and the blowout preventer, improve the sealing performance of the blowout preventer, and avoid the occurrence of blowout accidents.

[0045] The fixing assembly includes a second mounting plate 5 disposed on the inner wall of the first through hole 11 , a connecting spring 54 disposed on the second mounting plate 5 , and a fastener fastened to the connecting spring 54 . Plate 51; two sets of fixing components are respectively installed on both sides of the inner wall of the first through hole. After the oil delivery pipe is inserted into the first through hole, the oil delivery pipe is plac...

Abstract

The invention discloses a blowout preventer facilitating fixation of an oil delivery tube. The blowout preventer facilitating fixation of the oil delivery tube comprises a shell, fixing plates and a first equipment box, wherein the fixing plates are arranged on two sides of the shell; the first equipment box is arranged above the fixing plates; a first through hole is formed in the shell; a sealing assembly and a driving piece for driving the sealing assembly to move are arranged in the first equipment box; a supporting seat is arranged on the bottom of the first equipment box; a decompressionopening is formed in the inner wall of the first through hole; a decompression tube which is matched with the decompression opening is arranged in the shell; a fixing assembly is further arranged onthe inner wall of the first through hole; by the fixing assembly, the oil delivery tube which is inserted in the blowout preventer is fixed; and the oil delivery tube is prevented from vibrating during oil delivering, a connection effect of the oil delivery tube and the blowout preventer is affected, the airtightness of the blowout preventer is improved, and blowout accidents are avoided.

Description

technical field [0001] The invention belongs to the technical field of anti-leakage equipment, in particular to a blowout preventer which is easy to fix oil delivery pipes. Background technique [0002] The blowout preventer is a blowout device installed on the wellhead casing head to control high-pressure oil, gas and water during oil drilling. The blowout preventer is generally placed on the oil well head, and the oil delivery pipe needs to be inserted into the blowout preventer before being inserted into the oil well. When the oil delivery pipe is delivering oil, the pipe will vibrate to a certain extent, which will affect the connection effect between the oil delivery pipe and the blowout preventer, and reduce the blowout preventer. The sealing effect of the injector on the wellhead may easily cause blowout accidents. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a blowout preventer which is e...
