Abstract

The application discloses a pipe cable type coiled tubing connector and relates to the technical field of oil and natural gas production.The application comprises a load-bearing connecting part and a cable connecting part.The load-bearing connecting part adopts a slip type connecting structure, and the cable connecting part adopts a sliding contact type structure, so that the load-bearing connecting part can be relatively rotated to complete thread connection in the connecting process, and the cable connecting part can keep contact connection.The cable of the intelligent tool connecting part adopts a plug-in mode, and the cable of the pipe cable type coiled tubing adopts a welding mode.The sliding contact type structure reliably connects the cables at the upper end and the lower end of the connector, allows the lower joint and the middle joint to be screwed without affecting the connection of the cables, and realizes the connection of the coiled tubing and the connection of the cables at the same time.
