Coiled tubing electro-hydraulic tool seal joint

The utility model relates to coiled tubing drilling tools, in particular to a coiled tubing electro-hydraulic tool seal joint. A female fastener is designed at the upper end of a body of the coiled tubing electro-hydraulic tool seal joint, a righting body is mounted in the body, a drilling liquid channel is reserved between the righting body and the inner wall of the body, the upper end of the righting body is in threaded connection with a sealing core, and an O-type sealing ring is mounted on the sealing core. According to the coiled tubing electro-hydraulic tool seal joint, the fact that an inserting pin seat of a cable composite joint of a lower most electro-hydraulic tool can be sealed is achieved, the electro-hydraulic tool is maintained in an insulation state, normal work is achieved, the structure is simple, and mounting is convenient. The defects that an existing screw rod cannot seal the inserting pin seat of the cable composite joint of the lower end of the electro-hydraulic tool and the electro-hydraulic tool is short circuited are overcome.
