摘要： A control system for a subsurface safety valve references the surrounding annulus to put the operating piston in pressure balance. Depending on the configuration and which seal in the system fails, the various embodiments can differ in their failure modes. With the lower end of the piston exposed to annulus pressure all failure modes close the flapper. With the lower end of the piston exposed to tubing pressure, failure of any of the seals except one will result in flapper closure.
摘要翻译：用于地下安全阀的控制系统参考周围的环形空间，使操作活塞处于压力平衡状态。根据系统的配置和密封件的不同，各种实施例可以在其故障模式方面不同。随着活塞的下端暴露于环空压力，所有故障模式都关闭挡板。在活塞的下端暴露于管道压力下，任何密封件的故障都将导致挡板闭合。

摘要： Sealing devices such as packers comprise a metal foam material disposed on a surface. The metal foam material comprises an initial position comprising a plurality of pockets each having an initial volume and a compressed position in which at least one of the initial volumes of at least one of the plurality of pockets is reduced by compression of the metal foam material, thereby forming a seal. The seal may be formed directly between the metal foam material and a sealing surface such as an inner wall surface of a wellbore to divide an annulus of the wellbore. Alternatively, the seal may be at least partially formed between a sealing material disposed within one or more of the plurality of pockets that is extruded from at least one of the plurality of pockets during compression of the metal foam material.
摘要翻译：诸如封隔器之类的密封装置包括设置在表面上的金属泡沫材料。金属泡沫材料包括初始位置，该初始位置包括多个凹穴，每个凹穴具有初始体积和压缩位置，在该压缩位置中，多个凹穴中的至少一个凹穴的至少一个初始体积通过压缩金属泡沫材料而减小，从而形成密封。密封件可以直接形成在金属泡沫材料与诸如井眼的内壁表面之类的密封表面之间以分隔井筒的环形空间。可替换地，密封件可以至少部分地形成在设置在多个袋中的一个或多个袋内的密封材料之间，所述密封材料在金属泡沫材料的压缩过程中从多个袋中的至少一个袋挤出。

摘要： Methods and devices for retaining a packer element in a set condition within a wellbore and for preventing or minimizing extrusion of the packer element after setting. A packer device includes a plurality of deformable packer elements which radially surround a packer mandrel. One or more of the packer elements is contained against axial extrusion using a packer containment system. The packer containment system includes a flexible metal backup ring, which partially encases the packer element by substantially covering at least one axial side and a portion of the exterior radial surface of the packer element. The packer containment system also includes a plurality of annular support rings, or "petal rings" which have petal-shaped radial protuberances with slots between them.
摘要翻译：用于将封隔器元件保持在井眼内的凝固状态并用于在固化之后防止或最小化封隔器元件的挤压的方法和装置。封隔器装置包括径向围绕封隔器心轴的多个可变形封隔器元件。使用封隔器容纳系统，一个或多个封隔器元件被防止轴向挤出。封隔器容纳系统包括柔性金属支撑环，其通过基本上覆盖封隔器元件的至少一个轴向侧面和外部径向表面的一部分而部分地包住封隔器元件。封隔器容纳系统还包括多个环形支撑环或具有花瓣状径向突起的“花瓣环”，其间具有槽。
