摘要： An apparatus for use in a wellbore is disclosed. The apparatus includes a string for deployment into the wellbore, the string including at least one packer and an expansion tool downhole of the packer. The expansion tool further includes: a release device and a lock device inside a movable housing; wherein the lock device prevents shifting of the release device until the lock device is moved to an unlock position by application of a first force to the lock device. The release device is movable to a release position by application of a second force after the lock device has been moved to the unlock position. The movable housing is capable of moving over the release device after the release device has been moved to the release position to absorb at least one of contraction and expansion of the expansion tool.

摘要： A material that reacts to produced hydrocarbons acts as a latch to retain a stored potential energy force. In a specific application, a sliding sleeve valve is held away from a circulating port to allow drilling mud to be circulated out. Later, when the well is put on production, the lock that holds collets in a groove releases as exposure to produced hydrocarbons at a retaining sleeve makes it get soft. This, in turn, allows a spring force to run the collets out of their groove and straddle the circulation port between two o-rings on the shifting sleeve to close the port. The closure of the port directs produced hydrocarbons to screens that had been bypassed when mud was circulated out due to ports being the path of least resistance.

摘要翻译： 与生成的碳氢化合物反应的材料用作锁存器以保持存储的势能。 在具体应用中，将滑动套筒阀从循环端口远离，以允许钻井泥浆循环。 后来，当油井投入生产时，将夹头夹在凹槽中的锁释放，因为在保持套筒上暴露于生产的碳氢化合物，使其变软。 这反过来又允许弹簧力将夹头从其凹槽中移出并跨越换档套筒上的两个O形圈之间的循环端口以关闭端口。 由于港口是最小阻力的路径，港口的关闭将产生的碳氢化合物引导到已经绕过泥浆的筛网。

摘要： A tubular cutter that cuts with extendable and rotating blades has its depth of cut limited upon getting through the tubular to be cut. In a preferred embodiment, the tubular has a loosely mounted member exterior thereto to be engaged by the rotating cutters. When such engagement happens the effect is that the loosely mounted member serves as a cover to the cutters to prevent them from cutting other structures beyond the tubular to be cut. The loosely mounted member is grabbed by the rotating blades for tandem rotation this preventing further cutting action. The load on the mill drops noticeably so that surface personnel have a signal to stop hydraulic pressure to the drive mechanism to allow the blades to retract and the cutter to be removed.
