Abstract: A releasable production packer employs lock ring segments that are biased radially inwardly for engaging a mating pattern external to the packer mandrel. The mandrel has openings aligned with the segments and a release tool that latches to the mandrel for support and then moves the segments radially outwardly away from engagement with the mandrel so that the slips and sealing elements can extend axially and retract radially. After those movements the packer is retrieved. The release tools moves the locking segments only radially for the maximum mechanical advantage without risk of bending or deforming small parts.

Abstract: A grip a no goes in a subterranean tool to properly position grip members held radially outward with a cone on delivery of an uphole force. In the case of a subsurface safety valve that has a flow tube the slips are wedged into the flow tube when the grip tool lands on the no go in the subsurface safety valve and is jarred up. Jarring up using spang jars and weight bars can be repeatedly accomplished without releasing the grip tool from the flow tube. Jarring down unsupports the slips to allow them to retract while one or more springs can be used to prevent a re-grip of the flow tube. The grip tool can now be pulled out of the hole with the flow tube broken loose from accumulated debris for subsequent normal operation of the flow tube with the control system for the subsurface safety valve.

Abstract translation: 可释放的生产打包机使用径向向内偏置的锁环段，用于接合封隔器心轴外部的配合图案。 心轴具有与节段对准的开口和释放工具，该释放工具锁定到心轴以用于支撑，然后将节段径向向外移动远离与心轴的接合，使得滑动和密封元件可以轴向延伸并且径向缩回。 在这些动作之后，打包机被检索。 释放工具仅在径向移动锁定段以获得最大的机械优点，而不会有弯曲或变形小部件的风险。
