摘要： An apparatus and method allow gravel pack slurry to be placed in a borehole annulus from the toe towards the heel to reduce the pressure acting upon the heel of the borehole during the gravel placement operation. By reducing the pressure on the heel, the gravel pack slurry may be placed in longer sections of the borehole in a single operation. Additionally, excess slurry in the inner string can be disposed in the borehole annulus around the shoe track of the apparatus, and fluid returns can flow up the apparatus through a bypass.

摘要： A downhole sleeve has an insert movable in the sleeve's bore from a closed condition to an opened condition when a ball dropped in the bore engages an indexing seat in the sliding sleeve. In the closed condition, the insert prevents communication between the bore and the sleeve's port, while the insert in the opened condition permits communication between the bore and port. Keys of a seat extend into the bore to engage the ball and to move the insert open. After opening, the keys retract so the ball can pass through the sleeve to another cluster sleeve or to an isolation sleeve of an assembly. Insets or buttons disposed in the sleeve's port temporarily maintain fluid pressure in the sleeve's bore so that a cluster of sleeves can be opened before treatment fluid dislodges the button to treat the surrounding formation through the open port.

摘要： A downhole tool, such as a packer or liner hanger, has a mandrel on which slips are disposed for engaging a surrounding tubular downhole. When the tool is being run in or out of the hole, at least one magnetic component magnetically retains the slip adjacent the mandrel so the slip can be held away from the surrounding tubular. When the tool is set downhole, the initial magnetic retention can be broken, and the slips can be moved away from the mandrel to engage the surface of the surrounding tubular.

摘要： A non-metallic element system is provided as part of a downhole tool that can effectively seal or pack-off an annulus under elevated temperatures. The element system can also resist high differential pressures without sacrificing performance or suffering mechanical degradation, and is considerably faster to drill-up than a conventional element system. In one aspect, the composite material comprises an epoxy blend reinforced with glass fibers stacked layer upon layer at about 30 to about 70 degrees. In another aspect, a mandrel is formed of a non-metallic polymeric composite material. A downhole tool, such as a bridge plug, frac-plug, or packer, is also provided. The tool comprises a support ring having one or more wedges, an expansion ring, and a sealing member positioned with the expansion ring.

摘要： 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.
摘要翻译：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。
