Hydraulic sliding sleeve opening and closing tool

The utility model discloses a hydraulic sliding sleeve opening and closing tool. The hydraulic sliding sleeve opening and closing tool comprises a central pipe, wherein a liquid inlet channel is arranged inside the central pipe; a plurality of shoulders are arranged outside the central pipe; the end of the central pipe is connected with a lower joint; the central pipe is sleeved with a spring seat; the spring seat is connected with a baffle ring and then sleeves the central pipe; an upper pressing cap, a working block and a lower pressing cap are sequentially arranged between the spring seat and the baffle ring; a radial spring is further arranged between the spring seat and the working block; the upper part of a piston contacts the working block, and the lower part of the piston is connected with the lower joint; a sealing barrel is arranged in the piston; an axial spring is arranged between the piston and the lower joint. The motion of the sliding sleeve opening and closing tool is controlled in a hydraulic mode, so that a destination sliding sleeve can be selectively opened or closed, and the problems about mechanical opening and closing of the sliding sleeve are effectively avoided; the operation efficiency is improved, and the sliding sleeve of a horizontal well is operated by the cooperation of a continuous oil pipe, so that the problems about opening and closing of the sliding sleeve of the horizontal well are solved.
