[0002] The hydraulic blowout preventer mainly has two forms: the ram blowout preventer and the annular blowout preventer. The hydraulic ram blowout preventer is a well control blowout preventer used in downhole operations in oil fields. It is a device designed to prevent blowout accidents. , a device that can shut down the well in time and safely after the blowout occurs. At present, the hydraulic ram blowout preventer is driven by hydraulic pressure. Even if the current hydraulic blowout preventer can quickly seal the oil and gas well, since there will be a through hole for inserting the oil pipe on the ram, oil will still leak from the through hole when the oil pipe is lowered. If it is serious, it will still cause blowout, so we propose a hydraulic blowout preventer combination device

The invention discloses a hydraulic-driven blowout preventer combination device, and belongs to the technical field of blowout preventers. The hydraulic-driven blowout preventer combination device comprises a shell, an oil outlet hole is formed in the shell, oil cylinders are mounted on the left side and the right side of the shell, a piston is arranged in an inner cavity of each oil cylinder, anda piston rod is mounted on the side, close to the shell, of each piston; the sides, away from the pistons, of the piston rods extend into an inner cavity of the shell to be provided with gate plates,and the shell is provided with grooves matched with the gate plates; through holes are formed in the sides, away from the piston rods, of the gate plates; a sliding groove is formed in an inner cavity of each gate plate, and the sliding grooves communicate with the through holes; and a baffle is slidably arranged in an inner cavity of each sliding groove, and the baffles are connected with the inner walls of the sliding grooves through springs. The hydraulic-driven blowout preventer combination device is simple in structure and convenient to use; by arranging the oil outlet hole, the grooves,the oil cylinders, the pistons, the piston rods, the gate plates and the through holes, quick closing of a oil-gas well is facilitated; and compared with a manual blowout preventer, the hydraulic-driven blowout preventer combination device can better prevent well blowout, and the safety is improved.
