摘要： An apparatus for radially expanding and plastically deforming a tubular member. In some embodiments, the apparatus includes a support member and an adjustable expansion device coupled thereto. The adjustable expansion device includes a tubular support member with a plurality of circumferentially spaced apart inclined surfaces, a plurality of circumferentially spaced apart expansion segments movably coupled to the tubular support member, and an actuator for displacing the expansion segments relative to the tubular support member to thereby displace each of the expansion segments onto corresponding inclined surfaces.

摘要： A valve seat assembly is provided for rotatable valves. The assembly has concentric rings with a spring to apply force to cause the inner ring to slide within the outer ring. There is a sliding pressure seal between the sliding surfaces. The main seal, adapted to seal against a rotating seal element, is disposed on the outer ring. A second seal, adapted to seal against the wall of the cavity in a valve body, is disposed on the inner ring. A spring may be placed in a groove in the inner or outer ring and selected to provide a force to push apart the main seal and the second seal. The diameter of the sliding seal between the rings is greater than the diameter of the second seal and the diameter of the main seal.

摘要： A sealing apparatus for sealing an annulus between a mandrel and an outer tubular. The apparatus comprises a top seal ring and a bottom seal ring separated by a double-ramped cylinder, all mounted on the mandrel and fit within the inner diameter of the outer tubular. The sealing apparatus is placed on the mandrel in running in position. The mandrel and sealing apparatus are then placed downhole in the outer tubular. Once at the desired location, a load is applied to the top seal ring. Once the load reaches a predetermined magnitude, the ramp slides under and expands the bottom seal ring to form a pressure-tight seal with the outer tubular. Additional load placed on the top seal ring causes the top seal ring to slide over the ramp and expand. As the top seal ring expands, the top seal ring forms a pressure-tight seal with the outer tubular.
摘要翻译：一种用于密封心轴和外管之间的环的密封装置。该装置包括顶部密封环和由双斜面圆柱体隔开的底部密封环，全部安装在心轴上并且配合在外部管状物的内径内。将密封装置放置在心轴上运行就位。然后将心轴和密封装置放置在外管中。一旦在所需的位置，负载施加到顶部密封环。一旦载荷达到预定的大小，斜坡在底部密封环下滑动并膨胀，以形成与外管的压力密封。顶部密封环上的额外载荷使顶部密封环在斜坡上滑动并膨胀。当顶部密封环膨胀时，顶部密封环与外部管状物形成压力密封。
