Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of ocean engineering, especially relates to a righting device of a blowout preventer for ocean engineering drilling. BACKGROUND

[0002] During oil drilling, the blowout preventer is installed on the wellhead casing head and is a blowout prevention device for controlling high-pressure oil, gas and water. Because the structure in the stratum is very complex and there are many uncertain factors, there is a possibility of blowout at any time during drilling operation. In order to ensure the safety of the operation, the requirements for well control technology and well control equipment are very high. As the most important well control equipment, the blowout preventer needs to be quickly started to close the well in the event of overflow, well kick, blowout and other emergency conditions during drilling operation. If the blowout preventer fails at this time, it will lead to the occurrence of blowout and other serious accidents.

[0003] During operation, the concentricity of the blowout preventer with the crown block and the wellhead is very high. In the prior art, the blowout preventer is usually fixed on the flange of the blowout preventer by winding a steel wire rope. However, due to the large vibration during drilling construction, the steel wire rope is easily loosened, which causes the blowout preventer to shift. If the adjustment is not timely, it may cause the blowout preventer inner cavity to wear, the center to deviate too much, and the sealing effect of the blowout preventer to be affected, or even the sealing to fail, which has a great safety hazard.
