Detailed Description
The technical scheme of the invention is further explained by combining specific examples.
Examples
A hydraulic rotary tool for a branch well comprises a coupling 1, an upper connecting sleeve 2, a piston 3, a lower connecting sleeve 5 and a lower joint 6;
The coupling 1 is connected with the upper connecting sleeve 2, an annular space formed between the coupling 1 and the cylinder wall of the upper connecting sleeve 2 is used as an upper cavity for the movement of the piston 3, and a hydraulic hole is formed in the upper connecting sleeve 2;
the lower connecting sleeve 5 is connected with the lower joint 6, the upper connecting sleeve 2 is arranged in the lower connecting sleeve 5, and a lower cavity for the movement of the piston 3 is formed between the upper connecting sleeve 5 and the lower connecting sleeve 5;

In this embodiment, the locking key 3-1 is elongated.
In this embodiment, a sealing ring is arranged on the outer wall of the piston 3.
When the hydraulic rotary tool for the multilateral well is used, when the locking key on the piston is inserted into the locking key groove of the upper connecting sleeve, the upper pipe column and the lower pipe column can transmit torque through the locking key, so that the tool can transmit torque when a tail pipe enters the multilateral well hole and is blocked, and meanwhile, the pipe column is rotated to pass through a blocking point. A piston cavity is designed in the hydraulic rotary tool, a pin is arranged between the piston and the lower connecting sleeve, and the piston can be pushed to move upwards to shear the pin under certain pressure by water pressure. The pressure in the piston cavity can continuously push the locking key on the piston to move out of the locking key groove to remove the limit after the pin is sheared, so that the upper pipe column and the lower pipe column can rotate in the circumferential direction freely without transmitting torque to the lower pipe column under the condition that the upper pipe column and the lower pipe column are not separated, and the outer pipe columns of the upper joint and the lower joint are still connected and do not fall off through threaded connection. The upper part of the piston is provided with an elastic claw, and after the piston moves up to a certain position, the elastic claw of the piston is matched with an elastic claw groove on the coupling to realize locking, so that a locking key on the piston in the later period is prevented from moving downwards. The connector and the hollow whipstock are ensured to be smoothly matched with the seat hanger during the operation of the branch underground tail pipe.
