Abstract

A petroleum drill rod joint, which can transmitting electric power and signals, is used in the petroleum and the natural gas well drilling operations, and can perform the wire transmission of the electric power and the signals when power and circulating drilling fluid are transferred. The joint adopts a double shoulder structure; three conducting rings are respectively arranged on the outer wall at the front end of the main body of a tool joint pin and the inner wall of the main body of the corresponding female joint; the conducting rings are respectively connected with the main bodies of the tool joint pin and the female joint, and three conducting wires in the annular space of an inner tube; the conducting wires are uniformly distributed on the circumference; and the main bodies of the tool joint pin and the female joint and the annular space of the inner tube are filled and sealed with an insulating material. When the tool joint pin and the female joint are screwed together, the three pairs of conducting rings are respectively matched in a contact manner, so that the three conducting wires in the tool joint pin are respectively connected with the three conducting wires in the female joint, and thereby the wire transmission of the electric power and the signals can be performed. By using the petroleum drill rod joint, the electric power and the signal transmission from the ground to the underground can be realized and a wire information channel can be built for performing real-time bidirectional closed loop monitoring and controlling when the requirements of the drilling operation are met, such as power transmission, drilling fluid transmission, etc.
