基于可控弯接头钻井工具的偏心机构控制方法
A Control Method for Eccentric Mechanism of Controllable Bent Sub Drilling Tool
摘要
Abstract
A control method for eccentric mechanism of controllable bent sub drilling tool is proposed in this paper.The relationships between the offset azimuth and angle of guiding shaft and the rotational angles of inner eccentric ring and outer eccentric ring are derived.The unique corresponding relationship between the offset target of the eccentric mechanism and the clockwise rotation angles of inner eccentric ring and outer eccentric ring is obtained using the inverse method.The anticipated offset target of the eccentric mechanism can be achieved using the established method.关键词
