Double-shoulder raise boring machine torsion-resistant drill pipe capable of performing data transmission

Abstract

The invention discloses a double-shoulder raise boring machine torsion-resistant drill pipe capable of performing data transmission. A drill pipe body, a cable and a cable protection mechanism are included. The cable and the cable protection mechanism are both located in an axial middle hole of the drill pipe body, and mud channels of the cable and the drill pipe body are isolated through a liquidseal of the cable protection mechanism; the axis of the mud channels coincides with the axis of the axial middle hole; and the end faces of the large and small ends of a drill pipe connection head form double shoulders of a connection head. The technical scheme of the double-shoulder raise boring machine torsion-resistant drill pipe capable of performing data transmission does not hinder transmission of drilling fluid or slip casting grout, the drill pipe connection head is high in torque transmission capacity, and a drill pipe unit is steady in connection and stable in cable transmission signal.

Description

technical field [0001] The invention relates to the technical field of raising drilling rods. Specifically, it is a torsion-resistant drill pipe for a double-shouldered raise drilling rig capable of data transmission. Background technique [0002] During the construction process of modern raise drilling rigs, real-time monitoring of the drilling status of the bottom hole drilling tools is required, and the downhole drilling tools are judged, adjusted and corrected according to the monitored data to prevent unexpected problems. [0003] Drill pipe is an indispensable drilling tool in the exploration and development of oil, gas and coal mines. If the monitoring device is installed on the bottom hole assembly, real-time drilling data can be obtained through the cable transmission of the drill pipe, which is convenient for ground operators to work on the bottom of the well. Condition monitoring and prevention of downhole accidents. Wired transmission can reduce the influence o...

[0006] (2) The center cable is located at the center of the drill pipe. Since the center cable is wrapped by drilling fluid or mud, it cannot truly reflect the drilling information of the drill pipe.

[0007] (3) The drill pipe and the drill pipe are matched through the spring and the spring connector to realize the electrical connection of the central cable. However, in the actual use process, the drill rod and the drill pipe thread are matched, and the precision error is large, and the spring and the spring connector match Not good, can not achieve a solid electrical connection between drill pipe units, affecting the stability of the signal
