Hydraulic control system of integrated workover rig

The utility model discloses an integrated workover rig hydraulic control system which comprises a blowout preventer and a hydraulic control unit, the hydraulic control unit comprises a hydraulic pump,an overflow valve, a pressure reducing valve and an electromagnetic valve which are sequentially connected, the electromagnetic valve controls opening and closing of the blowout preventer, and the hydraulic pump is connected to the power output end of a workover rig. A workover rig serves as an initial power source, and the blowout preventer is finally controlled to be opened and closed through operation of the hydraulic control unit. By the adoption of the scheme, the danger is reduced, power is completely taken from an engine of the workover rig, other power is not needed any more, the useefficiency of the workover rig is greatly improved, and the expense for purchasing other equipment is saved. 本实用新型公开了一种一体化修井机液压控制系统，包括防喷器，还包括液压控制单元，所述液压控制单元包括依次连接的液压泵、溢流阀、减压阀和电磁阀，所述电磁阀控制防喷器的开闭，所述液压泵连接在修井车的动力输出端。由修井车作为初始动力源，通过液
