    • Sliding sleeve mechanisms including protective sheaths for debris protection are disclosed. Protective sheaths can be formed from materials such as composites, metal, foil, rubber, plastic, glass, ceramic, wire mesh, tape, etc. The protective sheaths can be substantially cylindrical shells (having one or more pieces), plugs in the flow ports, and/or tape or wire wrappings. The protective sheaths can be retained by recesses in the sliding sleeve or mechanical fasteners such as screws, pins, rivets, snap rings, bands, and buckles. The protective sheath can be outside or inside the sliding sleeve. The protective sheath can protect the sliding sleeve from debris by retaining grease that has been packed into the sliding sleeve for that purpose or positively preventing entry of debris into the sliding sleeve. The protective sheath can be cleared by permitting fluid flow through the sliding sleeve, which can act to destroy and/or wash away the protective sheath.
    • 公开了包括用于碎片保护的保护套的滑动套筒机构。 保护套可以由诸如复合材料,金属,箔,橡胶,塑料,玻璃,陶瓷,金属丝网,胶带等材料形成。保护套可以是基本上圆柱形的壳(具有一个或多个) 端口和/或磁带或电线包装。 保护套可以通过滑动套筒中的凹槽或诸如螺钉,销钉,铆钉,卡环,带和带扣的机械紧固件保持。 保护套可以在滑动套筒的外面或内部。 保护套可以通过保留已经包装在滑动套筒中的润滑脂来保护滑动套筒免受碎屑的影响,或者积极地防止碎屑进入滑动套筒。 可以通过允许流体流过滑动套筒来清除保护套,这可能会破坏和/或冲洗保护套。

    • A packer provides multiple seals when deployed downhole. Exposed to an activating agent, a swellable element on the packer's mandrel expands radially outward to form a seal with the borehole wall. One or more deformable elements, such as compressible packers or cup packers, are disposed on the mandrel adjacent the swellable element. These deformable element deform outward to the surrounding borehole wall to at least partially isolate the downhole annulus and the swellable element. Bias units releasably affixed on the tool adjacent the deformable elements can deform the elements. These bias unit can be released either by swelling of the swellable element or by fluid pressure. Once released, the bias units are axially biased toward the deformable elements to deform them. In this way, the packer can form multiple seals with the borehole wall, and the deformable elements can isolate the swellable element from the downhole annulus, which can keep the swellable element from degrading or being overly extruded.
    • 封隔器在井下部署时提供多个密封。 封隔器心轴上的可膨胀元件暴露于活化剂时,径向向外膨胀,以形成与钻孔壁的密封。 一个或多个可变形元件,例如可压缩封隔器或杯封隔器,设置在与可膨胀元件相邻的心轴上。 这些可变形元件向外变形到周围的钻孔壁,以至少部分隔离井下环和可膨胀元件。 可释放地固定在与可变形元件相邻的工具上的偏置单元可使元件变形。 这些偏置单元可以通过膨胀元件的膨胀或流体压力释放。 一旦释放,偏压单元被轴向偏向可变形元件以使它们变形。 以这种方式,封隔器可以与钻孔壁形成多个密封,并且可变形元件可以将可溶胀元件与井下环空隔离开,这可以保持可溶胀元件的降解或过度挤压。
