摘要： A packer system including a packer and a setting mechanism. The setting mechanism has a setting piston that is actuatable in response to a fluid pressure in order to set the packer with the setting piston. The setting mechanism prevents actuation of the setting piston until the pressure is decreased below a threshold pressure from a value greater than the threshold pressure. A method of setting a packer is also included.

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 10,000 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。由于一个或多个所描述的设计特征，可以使用大于10,000米的深度。

摘要： The removable plug features a solid material that is housed in a porous container that has its shape changed to transition from the run in shape to the set shape. A swage is moved through a passage in the container to enlarge the passage and move the container to a borehole wall. The passage is then closed such as with a flapper valve or by moving in a mandrel into the expanded passage and lodging the mandrel in the expanded passage. Various release techniques are described.

摘要： Disclosed herein is a tubular seal apparatus. The seal apparatus includes, a first tubular positioned coaxially with a second tubular having an annular space therebetween, a frustoconical portion at the first tubular having a first end and a second end, such that a radial dimension of the annular space is larger at the first end than at the second end and a tubular seal positioned within the annular space. The seal apparatus further includes an urging member in operable communication with the tubular seal, the urging member is axially movable relative to the frustoconical portion such that movement of the urging member toward the second end of the frustoconical portion urges the tubular seal into sealing engagement with the frustoconical portion and causes diametrical deformation of the tubular seal to thereby sealingly engage with the second tubular.

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： A downhole tool, comprising one or more separate packers and sliding sleeves in the preferred embodiment, is actuable from a nonelectrical signal transmitted from the surface to the tool. The signal is received at the tool by a control system located within the tool. The control system operates in conjunction with a power supply in the tool to accomplish tool actuation. In the preferred embodiment, the valve member is temporarily retained in a sealing position, isolating pressure in one chamber from a different pressure in an adjacent chamber. The valve member or piston is temporarily retained by a high-strength fiber, such as Kevlar.RTM., in the preferred embodiment. The control system actuates the power source to heat a resistance heating wire, which causes failure in the fiber. Other mechanisms to trigger pressure-equalization can be used. The fiber can be cut by a cutter actuated electrically. The piston can be retained by solder which is melted electrically. The piston can be designed to be substantially in pressure balance so that the fiber can effectively hold the piston in place until it is rendered inoperative by heating up a resistance wire from the power supply as triggered by the control circuit. Once the fiber fails, the piston is released and the pressure is equalized. The pressure-equalization can be used to shift a setting sleeve to set a packer or to open or close a sliding sleeve valve. Different valves can be actuated in series, using different control signals, or in parallel, using one control signal. In the alternative, the same valve can be actuated to open and then to close, depending on the procedures desired. The resistance wire is threaded into the fiber cable to ensure effective transmission of the heat for proper release of the piston when desired.
摘要翻译：在优选实施例中包括一个或多个单独的封隔器和滑动套筒的井下工具可从从表面传递到工具的非电信号致动。该信号通过位于工具内的控制系统在工具处接收。控制系统与工具中的电源一起操作以完成工具致动。在优选实施例中，阀构件暂时保持在密封位置，将一个室中的压力与相邻室中的不同压力隔离。在优选实施例中，阀构件或活塞由高强度纤维例如Kevlar TM暂时保持。控制系统启动电源以加热电阻加热丝，导致光纤故障。可以使用触发压力均衡的其他机构。纤维可以由电动切割机切割。可以通过电熔化的焊料保持活塞。活塞可以设计成基本上处于压力平衡中，使得纤维可以有效地将活塞保持就位，直到通过由控制电路触发而从电源加热电阻丝而使其不能工作。一旦纤维发生故障，活塞被释放并且压力相等。压力均衡可用于移动设置套筒以设置封隔器或打开或关闭滑动套筒阀。使用不同的控制信号，或者使用一个控制信号并联地驱动不同的阀。在替代方案中，根据所需的程序，相同的阀可被致动以打开然后关闭。电阻丝穿入纤维电缆，以确保有效传输热量，以便在需要时适当释放活塞。
