    摘要: A downhole apparatus for use in a tubular include a mandrel, a first slip, a cone, and a seal element. The mandrel, which can be permanent or temporary, has a first end shoulder. The first slip is disposed on the mandrel adjacent the first end shoulder, and the cone is disposed on the mandrel adjacent the first slip. The cone is movable relative to the first end shoulder to engage the first slip toward the tubular. The seal element is disposed on the mandrel adjacent the cone. At least a portion of the seal element is composed of a dissolvable metallic material and is expandable outward from the mandrel. The expanded portion of the seal element forms a metal seal against the tubular and seals off fluid communication in the annular space between the seal element and the tubular.

    摘要: A plug is engageable with a ball for seating in a tubular having an internal profile. The plug's body has a bore with a seat. Blocks disposed on the body are temporarily held in a retracted condition, but the blocks are biased outward to an expanded condition for engaging inside the tubular. The plug sets in the tubular with the blocks released from the retracted condition to the expanded condition. With the ball dropped downhole, the seat engages the ball so that fluid pressure is sealed from uphole to downhole through the bore. With applied fluid pressure against the seated ball, the plug can move through the tubular until the blocks seat in the internal profile of the tubing, sliding sleeve, or other component. A seal on the plug can then seal inside the tubular while the blocks seat in the profile and applied pressure pushes on the seated ball on the plug's mandrel.

    摘要翻译: 塞子可与球接合,用于安置在具有内部轮廓的管状物中。 插头具有带座的孔体。 设置在本体上的一个或多个块临时保持在缩回状态,但是一个或多个块被向外偏压到用于接合在管内的膨胀状态。 密封件设置在主体上用于密封管内。 塞子设置在管状中,其中一个或多个块从缩回状态释放到膨胀状态。 当球落在井下时,座椅接合球,使得流体压力从井上通过孔密封到井下。 随着对坐着的球施加流体压力,塞子可以通过管状件移动,直到块体位于管道,滑动套筒或其它部件的内部轮廓中。 然后,塞子上的密封件将密封在管状体内,同时块体位于轮廓中并且施加的压力推压在塞子心轴上的就座球上。
