摘要： In accordance with an illustrative embodiment of the present invention, apparatus for use in measuring weight-on-bit downhole during a drilling operation includes tubular telescoping members having resilient means reacting therebetween whereby relative longitudinal movement of the members is functionally relative to axial loading of a drill bit, sensor means mounted on one member and connected by linkage means to the other member for sensing the amount of relative movement, and means providing an elastic discontinuity in said linkage means for substantially isolating said sensor means from vibratory movement of said other member due to the cutting action of the bit.

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。

摘要： A releasable connection between the lower end of a running string and a well tool that is subject to being stuck in a well includes inner and outer members movable telescopically between contracted and extended positions, a tension sleeve connecting the members in the contracted position and being disrupted by a predetermined pull to allow telescoping movement, a stop nut to limit such movement in the extended position of the members, and a mechanism responsive to a certain number of cycles of telescoping movement for disabling the stop nut to allow complete release and separation of the members.
摘要翻译：运行钢丝绳的下端与被牢固固定在井中的钻井工具之间的可释放的连接件包括在收缩和伸展位置之间伸缩运动的内部和外部构件，连接构件处于收缩位置并被破坏的张紧套筒通过预定的拉力以允许伸缩运动，止动螺母限制在构件的延伸位置中的这种运动，以及响应于一定数量的伸缩运动循环的机构，用于禁用止动螺母以允许完全释放和分离会员
