摘要： A liner hanger/packer apparatus operates by sequential expansion of a slip ring and then a sealing element. The hanger slips are set by pressure on a seated ball actuating anchor slips to grip followed by a stroker assembly and a swage making a first movement. The ball seat is defeated and the liner is cemented. A pickup force extends landing dogs so that a subsequent set down force releases a flapper to close and closes off fluid ports associated with the anchor slips so that pressure on the closed flapper sets the anchor and strokes the swage a second stroke to set the sealing element. A rupture disc breaks in the flapper after further relative movement of mandrel components to open the fluid displacement ports so that the anchor is in pressure balance to backpressure developed from fluid moving through the now broken disc as the running tool is removed.

摘要： A shock absorbing device for a subterranean tool features a plurality of sequentially shearing shear pins that shear after incremental relative motion of the affected components. The travel stop is located internally to a series of spaced collets supported off a ring. Impact of an impact ring segments on the travel stop segments located internally to each collet provides a shock absorbing capability as the collets are placed in tension and deflect by radial flexing in opposed directions. The relatively moving parts are rotationally locked with the last of the shear pins to shear. A backup pair of contacting shoulders are provided if the primary engaging shoulders fail to support the lower end of the tool after impact. A snap ring maintains the parts in the shifted position after impact.

摘要： A liner hanger is initially set to the surrounding tubular. A standard bottom up cement job through a shoe at the liner bottom can be performed. If that job does not test satisfactory then the running tool can be unlatched at the packoff and raised beyond the liner hanger extension tubular so that a tack and squeeze job can be accomplished pumping the cement top down through the gaps in the liner anchor. The running tool can be re-latched to the liner hanger extension tube that is still unexpanded. Once re-locked into a groove in the extension the running tool for the liner hanger can be operated to set the seal and release the running tool from the groove in the extension to pull out of the hole. The liner hanger anchor and seal can be expanded into the set position by the running tool.

摘要翻译： 用于地下工具的减震装置具有多个顺序剪切的剪切销，其在受影响的部件的增量相对运动之后剪切。 行程停止位于内部，支撑在环上的一系列间隔的夹头。 冲击环段对位于每个夹头内部的行程挡块的冲击提供了冲击吸收能力，因为夹头被放置在张力中并通过在相反的方向上径向弯曲而偏转。 相对移动的部件与最后的剪切销旋转锁定以进行剪切。 如果主要接合肩部在冲击后不能支撑工具的下端，则提供备用的一对接触肩。 撞击环将冲击后的零件保持在移动位置。
