    摘要： The present invention generally relates to extrusion-resistant seals for an expandable tubular assembly. In one aspect, a seal assembly for creating a seal between a first tubular and a second tubular is provided. The seal assembly includes an annular member attached to the first tubular, the annular member having a groove formed on an outer surface of the annular member. The seal assembly further includes a seal member disposed in the groove, the seal member having one or more anti-extrusion bands. The seal member is configured to be expandable radially outward into contact with an inner wall of the second tubular by the application of an outwardly directed force supplied to an inner surface of the annular member. Additionally, the seal assembly includes a gap defined between the seal member and a side of the groove. In another aspect, a method of creating a seal between a first tubular and a second tubular is provided.

    摘要： A centralizer apparatus has been developed which, in one aspect, has a tubular body with an exterior surface, a collar movably emplaced around the tubular body and movable longitudinally thereon, a plurality of spring bows, each spring bow having a first end spaced apart from a second end, each spring bow biased outwardly from the tubular body, the first ends connected to the tubular body, the second ends connected to the first collar, so that upon movement of the first collar the spring bows move toward the tubular body. In one aspect the collar is connected to bottom ends of the spring bows and is initially movable to abut a stop on the tubular body so that from that point on the spring bows are pulled into another tubular, e.g. casing, as the centralizer apparatus moves down into the casing. In another embodiment two movable collars are used, one at each end of the spring bows.
