用于井增产措施的穿过生产管道的高压隔离系统
摘要：
一种压裂系统22，其包括压裂短管24，该压裂短管24安装到井口组件10上，以用于将压裂流体注入井口组件10下的井中。压裂系统22包括隔离套筒52和压裂短管24。隔离套筒52插入压裂短管24的轴向孔53中并且具有下端，该下端延伸到井口中来相对于压裂流体隔离并且保护井口组件10的部分。压裂短管24的内表面中的沟槽接收环形密封件以用于密封隔离套筒52与压裂短管24之间。将粘性流体注入沟槽中激起密封件，并且阻碍高压压裂流体在隔离套筒52与压裂短管24之间流动。
摘要（英）：

A fracturing system 22 includes a fracturing spool 24 that mounts onto a wellhead assembly 10 for injecting fracturing fluid into a well beneath the wellhead assembly 10. The fracturing system 22 includes an isolation sleeve 52 and fracturing spool 24. The isolation sleeve 52 inserts in an axial bore 53 of the fracturing spool 24, and has a lower end that extends into the wellhead to isolate and protect portions of the wellhead assembly 10 from the fracturing fluid. A groove in an inner surface of the fracturing spool 24 receives an annular seal for sealing between the isolation sleeve 52 and fracturing spool 24. Injecting a viscous fluid into the groove energizes the seal, and blocks high pressure fracturing fluid from flowing between the isolation sleeve 52 and fracturing spool 24.
