摘要： A diverter assembly can include a diverter having a deflection surface, and an annular seal device externally disposed and longitudinally displaceable on the assembly in response to a pressure differential being applied across the device. A well system can include a diverter assembly positioned in a casing, the assembly including a diverter and an annular seal device that seals off an annulus between the assembly and the casing, whereby a pressure differential across the device is reduced by movement of the device on the assembly. A method of sealing off an annulus formed between a diverter assembly and a casing can include positioning an annular seal device on a mandrel, the device being slidingly and sealingly engaged with an outer surface of the mandrel, connecting the mandrel to a diverter, and installing the assembly comprising the device, the mandrel and the diverter in the casing.

摘要： An assembly and method for completion of lateral wellbores is disclosed. The completion assembly includes a junction fitting with main and lateral legs, and a lateral completion string and anchoring device connected to the downhole end of the lateral leg and the uphole end of the junction fitting, respectively. A working string, positioned within the lateral leg, anchoring device, and lateral completion string, includes a setting tool that is removably connected to the anchoring device and a completion tool assembly located within the lateral completion string. The completion assembly is run by the working string into the wellbore. After setting the anchoring device, the working string conveys the completion tool assembly within the lateral completion string for gravel packing, fracturing, frac-packing, acidizing, cementing, perforating, and inflating packers, for example. After wellbore completion, the completion tool assembly is removed through the lateral leg of the junction fitting.
摘要翻译：公开了一种用于完成侧壁孔的组装和方法。完成组件包括分别具有主腿和侧腿的连接配件，以及分别连接到侧腿的井下端和连接配件的上孔端的横向完井柱和锚固装置。位于侧腿，锚固装置和横向完井柱内的工作绳包括可拆卸地连接到锚固装置的固定工具和位于横向完井柱内的完井工具组件。完成组件由工作柱运行到井筒中。在设置锚定装置之后，工作线例如将用于砾石填充，压裂，压裂填充，酸化，固井，穿孔和充气封隔器的横向完井柱中的完井工具组件传送。在井筒完井之后，完井工具组件通过接头配件的侧腿去除。

摘要： A method of orienting a well tool can include setting down weight on an orienting device, thereby securing in position an engagement member that was previously free to displace circumferentially in the device, and after the securing, engaging the engagement member with an orienting profile. Another method of orienting a well tool can include compressing the orienting device between sections of a tool string, thereby securing in position an engagement member that was previously free to displace circumferentially in the device, the securing step including deforming a structure of the orienting device, and after the securing, engaging the engagement member with an orienting profile.
摘要翻译：定向井工具的方法可以包括在定向装置上设置重量，由此将先前自由地在装置周向位移的接合构件固定在适当位置，并且在固定之后，使接合构件与定向轮廓接合。定向井工具的另一种方法可以包括在工具串的部分之间压缩定向装置，从而将先前自由地在装置周向位移的接合构件固定在适当位置，固定步骤包括使定向装置的结构变形，并且在固定之后，使接合构件与定向轮廓接合。
