摘要： In accordance with presently disclosed embodiments, a system and method for rotationally orienting two wellbore tool components on a tool string relative to each other is provided. The system may include an alignment sub that is simple to operate and allows for quick adjustments to the relative orientations of downhole tool components. The disclosed alignment sub may include a first tubular component on one side and a second tubular component on the other side, and these tubular components are coupled together. The disclosed alignment sub utilizes an axially deformable and variable length sleeve attached to the first tubular component and adjacent to a tip of the second tubular component. The sleeve may provide an appropriate standoff distance between the opposing tubular components while enabling the components to be rotated relative to each other up to at least one full rotation about an axis of the alignment sub.
摘要翻译：根据目前公开的实施例，提供了用于将两个井眼工具部件相对于彼此旋转地定向在工具串上的系统和方法。该系统可以包括对准子，该对准子操作简单并且允许对井下工具部件的相对定向进行快速调整。所公开的对准接头可包括在一侧上的第一管状部件和在另一侧上的第二管状部件，并且这些管状部件联接在一起。所公开的对齐接头利用附接到第一管状部件并邻近第二管状部件的末端的轴向可变形且可变长度的套筒。套筒可以在相对的管状部件之间提供适当的间隔距离，同时使得部件能够相对于彼此旋转至围绕对准接头的轴线至少一个完整的旋转。

摘要： A well tool has an inner and outer component arranged to move relative to one another and defining a shear juncture therebetween. A shear member spans the shear juncture. The shear member has first portion with a different cross-sectional area than a second portion. A cam surface is associated with the inner or outer component and abuts the shear member. The cam surface moves the shear member as the inner and outer components move relative to one another and changes the shear member from having the first portion aligned with the shear juncture to having the second portion aligned with the shear juncture.
