Hydraulic rotary tool

A hydraulic rotary tool is applied to the technical field of oil field well repair operation, which is characterized in that, the hydraulic rotary tool is composed of a body and a throttle valve. hydraulic holes are provided on the body, the included angle of the hydraulic holes and an inner cavity circumferential tangent line is 45 degrees, and the central line of the hydraulic holes is tangent with the inner wall of the inner cavity, four hydraulic holes are symmetrically distributed in the circumferential direction of the body. Two rows of eight hydraulic holes with diameters of 20 mm are distributed on the body. The throttle valve is welded and fixed in the hydraulic holes. The utility model has effects that, the hydraulic rotary tool is mounted above the tools such as a casing tube shaper, a milling tap and a shoe milling device to generate the torque by the hydraulic pressure and drive the tool at the lower part to rotate, the hydraulic rotary tool can overcome the friction effectively in order to improve the shaping and cutting capabilities of the shaper and the milling tap. In addition, the structure is reasonable, the field use is easy and simple, and the utility model can be extensively used for multiple downhole well repair tools.
