摘要： An isolation sleeve extends from an adapter into the bore of a tubing head to isolate high pressure frac fluid from the body of the tubing head. The isolation sleeve may be installed by a running tool that can screw the sleeve onto a packoff bushing located within the tubing head. The running tool can also retrieve the isolation sleeve by unscrewing it from the packoff bushing.
摘要翻译： 隔离套管从适配器延伸到管头的孔中，以从管头的主体隔离高压压裂流体。 隔离套管可以由可以将套筒拧到位于管头内部的包装衬套上的运行工具来安装。 运行工具还可以通过从包装衬套上拧下来检索隔离套筒。

摘要： A reinforced wellhead member for use during fracing operations. The wellhead member is preloaded at a flange section by creating compressive stresses via a ring that interacts with a tightening nut on a bolt. The bolt is rigidly attached to an adapter which may also be modified to create stresses on the flange of the wellhead member. The induced stresses counter the tensile stresses experienced by the flange during fracing operations, allowing a standard wellhead member to be utilized.
摘要翻译： 在加工作业期间使用的加固井口构件。 井口构件通过与螺栓上的紧固螺母相互作用的环产生压缩应力而在法兰部分预加载。 螺栓刚性地连接到适配器，该适配器也可以被修改以在井口构件的凸缘上产生应力。 感应应力抵抗法兰在分段作业过程中经受的拉伸应力，允许使用标准的井口部件。
