FIELD: oil and gas industry.
SUBSTANCE: invention can be used in combination with a lifting and repair unit APR-60/80 when servicing oil and gas wells for remote control of a preventer equipped with a hydraulic drive for the tools. A preventer hydraulic control power plant is claimed, containing a rectangular frame on which metal frames are fixed, located in pairs in mutually perpendicular directions along one long side of the frame and on its opposite short sides and made of interconnected racks. Blocks of electric accumulators are placed on each frame. On the second long side of the frame there is a tank with a working medium in the form of multigrade oil, equipped with a heating module. In front of the tank there is a distributor block connected to the tank and a high-pressure hydraulic pumping station of 25 MPa by means of hydraulic lines. The electric accumulator blocks are connected to the electric and electronic control unit connected to the charge control and control unit of the electric storage battery unit, the hydraulic high pressure pumping station and the hydraulic distributor unit, as well as to the remote backup electric and electronic control unit using electric lines.
EFFECT: reduction in the size, weight and dimensions of the equipment, possibility of increasing pressure of the oil flow while maintaining the reliability of the control of the preventer.
