摘要： A system and method facilitate directional drilling. The technique employs an orienting tool which may be connected into a coiled tubing drilling system to selectively orient a drilling assembly. The orienting tool is able to cause relative rotation of an outer housing to orientate a tool face. The relative rotation is facilitated by utilizing floating members, such as a floating piston and a floating nut, in the internal orientation assembly. The floating member or members are decoupled in a radial direction to better facilitate the relative rotation of the housing with respect to components of the internal orientation assembly.
摘要翻译：系统和方法有助于定向钻井。该技术采用定向工具，其可连接到连续油管钻井系统中以选择性地定向钻井组件。定向工具能够引起外壳的相对旋转以使工具面定向。通过在内部定向组件中利用诸如浮动活塞和浮动螺母的浮动构件来促进相对旋转。浮动构件在径向方向上分离，以更好地促进壳体相对于内部定向组件的部件的相对旋转。
