Abstract

The present disclosure provides a device for power transmission and signal transfer between the stator and the rotor of a screw drilling tool. The present disclosure can replace the wireless communication technique between the rotary steering tool and the integrated MWD/LWD, omit the upper mud generator above the rotary steering tool, and thereby realize power transmission and signal transfer between the stator and the rotor of the screw drilling tool.
