摘要： A collet assembly has a housing and the collets disposed on flexible fingers connected to the housing at their opposed ends. A surrounding landing sleeve stops the assembly so that collets are aligned with a recess in a landing collar that is part of a surrounding tubing string. Once set the landing sleeve transmits compressive loads so that compressive stress essentially bypasses the finger structure supporting the collets. The fingers are initially tapered toward a longitudinal axis so that when internally supported they assume an aligned orientation to the housing axis to allow greater tensile loading and to provide a retraction force when the housing is to be removed after the collet support is removed.
摘要翻译：夹头组件具有壳体，并且夹头设置在柔性指状物上，在其相对端部处连接到壳体。周围的着陆套筒停止组装，使得夹头与作为周围油管柱的一部分的着陆轴环中的凹部对准。一旦设置，着陆套筒就会传递压缩载荷，使得压缩应力基本上绕过支撑夹头的手指结构。手指最初朝着纵向轴线渐缩，使得当内部支撑时，它们采取与壳体轴线对齐的取向，以允许更大的拉伸载荷，并且在夹套支撑件被移除之后要移除壳体时提供回缩力。

摘要： Apparatuses for restricting fluid flow through a well conduit comprise a housing having a longitudinal bore and a seat disposed within the bore. The seat has a first position when the apparatus is in the run-in position and a second position when the apparatus is in the set position. A plug element support member has a retracted position when the apparatus is in the run-in position and an extended position when the apparatus is in the set position. A plug element adapted to be disposed into the bore and landed on the seat to restrict fluid flow through the bore and the well conduit is used to move the plug element support member from the retracted position to the extended position, thereby providing support to the plug member landed on the seat.

摘要： A plurality of rows of locking dogs are provided with housing flexibility between rows to allow them to share a shear loading while leaving enough structural integrity in the housing to define the windows through which the dogs emerge. The dogs can also have extensions with a surface that grippingly engages the housing adjacent the window on extension of the dogs such that loads can transfer from the housing into the extension and into the profile in which the dog is disposed rather than passing the shear stress through the window edge into the dog that is in the profile. The dog configuration can also share the load on multiple contact surfaces of the housing to reduce stress at each contact location.

摘要翻译：多行锁定爪在行之间设置有壳体柔性，以允许它们共享剪切载荷，同时在壳体中留下足够的结构完整性以限定出口所通过的窗口。这些狗还可以具有延伸部，该延伸部的表面在狗的延伸部分上与窗口邻近地握紧地接合壳体，使得负载可以从壳体转移到延伸部中并且进入配置有狗的轮廓中，而不是使剪切应力穿过窗户边缘进入配置文件中的狗。狗配置也可以在壳体的多个接触表面上共享负载以减少每个接触位置处的应力。
