摘要： An expandable packer or anchor is disclosed. It features a gripping device integral to or mounted in a sleeve over the mandrel. Upon expansion, a sealing element engages an outer tubular and the gripping device, such as wickers on slips, preferably digs into the outer tubular. The expansion is preferably by pressure and can incorporate pressure intensifiers delivered by slick line or wire line. Release is accomplished by a release tool, which is delivered on slick line or wire line. It stretches the anchor or packer longitudinally, getting it to retract radially, for release. The release tool can be combined with packers or anchors that have a thin walled feature in the mandrel, to release by pulling the mandrel apart.

摘要： An expandable packer or anchor is disclosed. It features a gripping device integral to or mounted in a sleeve over the mandrel and mating undulating surfaces to help maintain grip under changing load conditions. Upon expansion, pressure on a sealing element is enhanced by nodes to increase internal pressure as it engages an outer tubular. Adjacent retaining rings limit extrusion and enhance grip. A gripping device, such as wickers on slips, preferably digs into the outer tubular. The expansion is preferably by pressure and can incorporate pressure intensifiers delivered by slick line or wire line. Release is accomplished by a release tool, which is delivered on slick line or wire line. It stretches the anchor or packer longitudinally, getting it to retract radially, for release. The release tool can be combined with packers or anchors that have a thin walled feature in the mandrel, to release by pulling the mandrel apart.

摘要： In a release system for a packer the release ring is minimally exposed in the wellbore and is actuated by a release tool, which comprises a collet and cone with a relative movement feature. In the preferred embodiment, the release ring has alternating cuts and a built in radially outward bias. The ring is held in locked position by bands, which are broken by the action of the releasing tool.

摘要： An improved cage slip system is disclosed. The cage is constructed so that the cones which actuate the slips extend into the cage openings. The radial extension of the slips is limited so as to retain them if they are extended in an unsupported situation. The cones have a maximum outside dimension equal to the outside dimension of the cage so as to increase the rating of the slips by increasing the bearing area of the cones on the slips. The beneficial features of the cage design are retained while a greater degree of radial expansion of the slips is possible allowing minimization of tool inventory for situations where a lighter wall casing requires further slip extension. The release system allows the lower cones to be driven out from under the lower slips, thus facilitating release of the grip of the lower slips from the casing for extraction of the packer. The mechanical release is functional through the mandrel, whether tension or compression is placed on the mandrel. Alternative designs are presented for the capture of the lower cone by the cage.
摘要翻译：公开了一种改进的保持架滑动系统。保持架被构造成使致动滑动件的锥体延伸到保持架开口中。滑块的径向延伸受到限制，以便如果它们在不受支撑的情况下延伸，则保持它们。锥体具有等于笼的外部尺寸的最大外部尺寸，以便通过增加滑动件上的锥体的承载面积来增加滑移的额定值。保持架设计的有益特征被保留，同时可以更大程度地进行滑动的径向膨胀，从而允许在更轻的壁套管需要进一步滑动延伸的情况下最小化工具库存。释放系统允许下锥体从下滑动件下面被驱除，从而便于将下滑动件的把手从壳体释放以提取封隔器。机械释放通过心轴起作用，无论张力还是压缩被放置在心轴上。提出了替代设计，用于通过保持架捕获下锥。

摘要： A sealing element system for a downhole packer reduces the tendency of the elements to extrude. Mechanical limits are provided to the amount of force that can be passed onto the uppermost and lowermost components of a sealing element system by providing a limit on the longitudinal compression available against a gauge ring. The gauge rings are roughened to also grab the uppermost and lowermost elements to fight the tendency to extrude. The uppermost and lowermost elements are configured with an external groove to control the way they deform into a sealing relationship with the tubing and casing so that extrusion into the gap is reduced.

摘要： A hydraulically actuated setting tool has a plurality of pistons that move in tandem when unlocked. The pistons are initially in pressure balance to take a load off a single locking mechanism that retains all the pistons. The pistons move due to admission of hydrostatic and/or applied pressure from the annulus on one side of each piston with an opposite side exposed to atmospheric pressure. The locking member is exposed to the annulus and is located away from any atmospheric chambers associated with the pistons. In this manner the components can be made thicker to resist burst and collapse pressure and the loads on the locking member reduced due to initial piston pressure balance configuration. Depths of greater than 8,000 meters can be used due to one or more of the described design features.
摘要翻译：液压致动的固定工具具有多个在解锁时串联移动的活塞。活塞最初处于压力平衡状态，从而保持所有活塞的单个锁定机构的负载。活塞由于静压和/或施加的压力从每个活塞的一侧的环形空间移动，相对侧暴露于大气压力。锁定构件暴露于环形空间并且位于远离与活塞相关联的任何大气室。以这种方式，可以使部件更厚以抵抗爆裂和压缩压力，并且锁定构件上的负载由于初始活塞压力平衡配置而减小。由于所描述的一个或多个设计特征，可以使用大于8000米的深度。
