The invention discloses a blowout preventer for oil development suitable for various pipeline diameters, which comprises a shell and an oil pipeline. Pistons are arranged on both sides of the shell, and a cavity is arranged inside the shell. There is a driving motor, and the two ends of the driving motor are provided with telescopic rods. One side of the telescopic rod is provided with a mounting tube, and one end of the mounting tube is provided with a first bolt. There is an annular connection block at the bottom of the body, a second bolt is provided between the annular connection block and the annular installation block, a connection line is provided on the surface of the shell, and a controller is provided at one end of the connection line. The sliding connection of the installation pipe allows the installation pipe to move left and right, so that the installation pipe can discharge and spray oil pipelines of any width; the bottom end of the installation pipe is provided with a chuck so that the installation pipe can be easily inserted into the annular socket. The second bolt can quickly fix the blowout preventer above the oil pipeline.
Description
technical field [0001] The invention relates to a blowout preventer for petroleum exploitation, in particular to a blowout preventer for petroleum exploitation suitable for various pipe diameters, and belongs to the field of petroleum exploitation. Background technique [0002] The blowout preventer is used to close the wellhead in the process of oil testing, workover, and completion to prevent blowout accidents. It combines the functions of full seal and half seal. It has the characteristics of simple structure, easy operation, and high pressure resistance. , is a safety sealing wellhead device commonly used in oil fields to prevent blowout. In specific use, the blowout preventer is installed on the wellhead casing head. When the oil and gas pressure in the well is high, the blowout preventer can seal the wellhead. When heavy mud is pressed from the drill pipe, there is a four-way under the ram, which can replace the gas-invaded mud and increase the pressure of the fluid ...
