Research on Measurement and Control System of Eccentric Mechanism Based on the Well Trajectory Control Tool

Abstract:

Eccentric mechanism is the core of the high deflecting well trajectory control tools, the control and measurement accuracy of the eccentric mechanism decides the accuracy of the whole tool. In this paper, on the basis of the eccentric mechanism’s principle, developed a set of method and apparatus to measure the space location of the internal and external eccentric ring and control the rotation angle by using Hall sensors and electromagnetic clutch device, so that could measure and control the bending direction and offset size accurately. Additionally, the paper analyzed Underground-Ground interactive communication interface and encoding rules, completing a real-time monitoring closed loop drilling system.
