摘要： A hydraulically operated downhole tool located at a depth where control line hydrostatic pressure would normally set the tool is temporarily isolated from hydrostatic pressure and changes thereto from well exposure or downhole operations until properly located. A removable barrier is placed in the control line to the tool at a height from the tool that limits the hydrostatic force exposed to the actuation mechanism for the tool. The preferred barrier is a rupture disc that is selectively broken with applied pressure from a remote location, typically the surface above the well. The mounting depth of the barrier can be varied to control the maximum hydrostatic pressure seen by the tool as it is advanced to the intended position.

摘要： The frack plug has a sealing element that reforms when set to hold differential pressure. The element is granular with adhesive to hold the granular particles together but allow the shape to reform under setting force. The adhesive can be broken down with a chemical agent or in other ways to allow the seal to reform to the sealing position at the desired depth. As a result the structural components can disintegrate and the seal assembly can fragment into small pieces that can be circulated out of the well or allowed to drop to the hole bottom. The seal can have particles of controlled electrolytic materials (CEM), natural or synthetic sand, swelling or non-swelling rubber. The assembly can contain pellets that selectively release to initiate the breakdown of the structural components of the frack plug.
摘要翻译：弹簧插头具有密封元件，当设置为保持压差时，该密封元件将进行改造。该元件是具有粘合剂的颗粒状的以将颗粒状颗粒保持在一起，但允许形状在凝固力下进行改性。粘合剂可以用化学试剂分解，或以其它方式使密封件以期望的深度重新形成密封位置。结果，结构部件可能崩解并且密封组件可能会碎裂成小块，其可以从井中循环出来或允许其下落到孔底部。密封件可以具有受控电解材料（CEM），天然或合成砂，膨胀或非膨胀橡胶的颗粒。组件可以包含选择性释放以引发破裂塞的结构部件的击穿的颗粒。

摘要： A compression set sealing element preferably 85A-95A TDI-Ester Polyurethane is compressed axially and retained against extrusion by CEM anti-extrusion rings. The compressed state of the sealing element is locked in by a degradable lock ring assembly. The mandrel is secured to an upper end of a slip cone and a breakable slip ring is secured by a wireline setting tool until the set position is reached. The slip ring breaks into segments that are pulled up the slip cone as the setting tool pushes on a sleeve to axially compress the sealing element and lock in the set. The sealing element is retained against extrusion by CEM anti-extrusion rings. When the setting tool is removed a ball seat is exposed for delivery of a ball to build pressure into the formation for fracturing. The entirety of the plug then disintegrates from well fluid exposure.
摘要翻译：压缩永久密封元件优选85A-95A TDI-Ester聚氨酯被轴向压缩并保持抵抗CEM抗挤出环挤压。密封元件的压缩状态由可降解的锁环组件锁定。心轴被固定到滑动锥体的上端，并且可滑动的滑环通过有线设置工具固定，直到到达设定位置。当安装工具推动套筒以轴向压缩密封元件并锁定在组件中时，滑环突破成滑动锥体上拉的段。密封元件通过CEM抗挤压环保持抵抗挤出。当固定工具被移除时，球座被暴露以输送球以将压力施加到地层中用于压裂。然后，整个塞子从良好的流体暴露中分解。

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： An articulated debris barrier folds on itself to extend radially to span a surrounding annular gap when the tool associated with it is set. The debris barrier can be used with a packer or bridge plug. The set position of the packer or plug is locked and another lock holds the extended position of the debris barrier. The debris barrier lock can be a snap ring that extends into a groove brought into alignment with it during the setting. Alternatively the lock for the debris barrier can be a body lock ring. In either case, release and retrieval of the packer or plug involves undermining of the locking feature for the debris barrier so that the debris barrier can extend while retracting from the borehole wall so that the barrier and the associated packer or plug can be removed together.
摘要翻译：当与其相关联的工具被设置时，铰接的碎片障碍物在其自身上折叠以径向延伸以跨越周围的环形间隙。碎片屏障可以与封隔器或桥塞一起使用。封隔器或插头的设置位置被锁定，另一个锁定保持碎片屏障的延伸位置。碎片阻挡锁可以是在安装期间延伸到与其对准的凹槽中的卡环。或者，用于碎片障碍物的锁可以是身体锁定环。在任一情况下，封隔器或插塞的释放和取出包括破坏碎片屏障的锁定特征，使得碎片阻挡物能够在从井壁延伸回缩的同时延伸，使得阻挡层和相关的封隔器或塞可以一起被移除。
