摘要： A downhole plug and a method of releasing a portion of the plug. The plug has a run-in configuration, a deployed configuration, and a released configuration. The plug includes a mandrel, a bull nose, and a cone and an expandable slip. The expandable slip has an external gripping surface. The plug includes an inner and outer sleeve, where the outer sleeve is concentric around the inner sleeve and the inner sleeve is concentric with the mandrel. The inner sleeve is slidable about but releasingly coupled to the mandrel. The inner sleeve is slidable about the outer sleeve but releasingly coupled to the outer sleeve in both the run-in configuration and in the deployed configuration. The inner sleeve is coupled with the mandrel in the run-in configuration and in the deployed configuration, but uncoupled and slidable about the mandrel in the released configuration.

摘要： A subterranean well tool which is manipulatable by a control mandrel between run-in and set positions within a wellbore having casing includes an assembly which provides a selectively operable lock to prevent premature activation of the assembly from the run-in position towards the set position until a predeterminable compressive load is carried through the well tool by the control mandrel to manipulate the assembly from a first initial position to an intermediate position and thereafter to a final extended position.
摘要翻译：一个地下钻井工具，其可通过控制心轴在具有壳体的井眼内的入口和设定位置之间操纵，该组合件提供可选择性地操作的锁，以防止组件从入口位置向设定位置过早启动，直到预定的压缩载荷通过控制心轴通过井工具运送，以将组件从第一初始位置操纵到中间位置，然后到最终延伸位置。

摘要： An apparatus for deploying and activating a downhole tool activated by an explosive charge such as a drill pipe cutter or hole puncher. The apparatus includes a sealing member with an external wedge-shaped profile that forms a metal-to-metal partial seal with a profile at the top end of a pipe joint in a drill pipe string. The apparatus includes an impact force absorbing device that maintains a firing rod in a non-actuated position during impact of the apparatus. The apparatus includes a differential pressure piston that actuates at a pre-determined well bore pressure to release the firing rod to activate the downhole tool.
摘要翻译：一种用于展开和激活由诸如钻杆切割器或打孔机的爆炸装料激活的井下工具的装置。该装置包括具有外部楔形轮廓的密封构件，该外部楔形轮廓形成金属对金属部分密封件，其具有在钻杆管柱中的管接头的顶端处的型材。该装置包括冲击力吸收装置，该冲击力吸收装置在冲击装置期间将击发杆保持在非致动位置。该装置包括差压活塞，该压差活塞以预定的井筒压力致动以释放发射杆以致动井下工具。
