The invention discloses an oil tube blowout preventer used for oil exploration. The blowout preventer includes an outer shell; the outer shell is provided with an oil tube channel; the inner side wallof the oil tube channel is symmetrically provided with two ports; the end ports, away from the oil tube channel, of the ports are provided with installation blocks; the inner side walls of the portsare provided with annular installation grooves corresponding to the installation blocks; the ends, away from the bottoms inside the annular installation grooves, of the installation blocks are fixedlysleeved by clamping rings; the clamping rings are fixedly connected to the outer shell through multiple locking screws; the installation blocks are provided with cavities; the cavities are provided with pistons; the pistons are rotatably connected to the inner side walls of the cavities in a sealing manner; one sides of the pistons are fixedly connected to connecting rods; and the ends, away fromthe pistons, of the connecting rods pass through the inner side walls of the cavities and fixedly connected to flashboards. The blowout preventer is simple in structure and convenient in usage; and through hydraulic control, pressure difference can be formed on the two sides of the pistons, and therefore, the convenient moving of the positions of the flashboards can be achieved, the closing and opening of the oil tube channel can be realized, physical output of workers can be reduced, and working efficiency can be enhanced.
Description
technical field [0001] The invention relates to the technical field of an oil pipe blowout preventer device, in particular to an oil pipe blowout preventer device used for oil exploration. Background technique [0002] Coiled tubing blowout preventer is a kind of wellhead blowout preventer in the field of oil and gas field development. Coiled tubing blowout preventer can effectively reduce the frequency of blowout accidents during coiled tubing operations, thereby reducing damage to the environment and economic losses. In the prior art, the coiled tubing preventer is usually a four-ram blowout preventer, which reduces the frequency of blowout accidents during the process of lifting and lowering the coiled tubing, but the traditional blowout preventer needs to turn the handle to realize the ram The opening and closing wastes the physical strength of the staff and reduces work efficiency. In order to solve the above problems, we propose a tubing blowout preventer device for o...
