Vertical continuous oil pipe blowout preventer

Abstract

The invention discloses a vertical continuous oil pipe blowout preventer. The vertical continuous oil pipe blowout preventer sequentially comprises a half seal part, a suspension part, a cutting partand a full seal part from bottom to top. According to the continuous oil pipe blowout preventer of a vertical structure, a transverse structure is changed into a vertical structure, space is saved foroperation construction, operation is facilitated, and operation accidents are reduced. A full seal becomes active closing from passive closing, and the whole blowout preventer becomes safer. A notchbecomes rotary cutting from straight cutting and becomes a circular port from a linear port, and usage becomes smoother. The suspension is controlled by hydraulic pressure, interlocking becomes, and accidents caused by the original necking phenomenon of a continuous oil pipe are relieved. Through the annular half seal design, the half seal is more reliable, adaptability is higher, the situation that due to deformation and the necking phenomenon of an original gate plate type half seal, the half seal is in failure is avoided, and the accident happening probability is reduced.

Description

technical field [0001] The invention relates to an oil field equipment, in particular to a vertical coiled tubing blowout preventer. Background technique [0002] In the process of oil exploitation, the coiled tubing loading vehicle is called a universal operation vehicle, and in the use of coiled tubing, four-layer special blowout preventer is necessary, and the four-layer blowout preventer currently used is 4FZ blowout preventer That is, the four-ram blowout preventer, and the 4FZ blowout preventer is a four-layer horizontal blowout preventer. Because of the horizontal structure, there are eight hydraulic cylinders extending outwards, which brings great pressure to the operator during the actual operation. Inconvenience, sometimes also cause personnel trauma, at the same time, in the application, there are some inconveniences, so the present invention designs a more suitable vertical structure. Contents of the invention [0003] The object of the present invention is to...
