    摘要: The present invention generally relates to an anchor seal for an expandable tubular assembly. In one aspect, an anchoring seal assembly for creating a seal portion and an anchor portion between a first tubular that is disposed within a second tubular is provided. The anchoring seal assembly includes an expandable annular member attached to the first tubular. The annular member has an outer surface and an inner surface. The anchoring seal assembly further includes a seal member disposed in a groove formed in the outer surface of the expandable annular member. The seal member has one or more anti-extrusion spring bands embedded within the seal member, wherein the outer surface of the expandable annular member adjacent the groove includes a rough surface. The anchoring seal assembly also includes an expander sleeve that is configured to radially expand the expandable annular member to create the seal portion and the anchor portion.

    摘要: A system for facilitating the insertion of a tool into a wellbore, especially a non-vertical wellbore. In one embodiment a tool is fixable in a wellbore and includes centralizing, friction-reducing members that serve to keep the body of the tool off the walls of the wellbore. In another embodiment the tool includes a wiper ring that partially fills an annular area formed between the centered tool and the wellbore walls. The surface of the ring facing the upper end of the wellbore provides fluid resisting piston surface and permits the centered tool to be pumped down the wellbore more effectively.

    摘要: The present invention generally provides a pressure isolation plug for managing a wellbore with multiple zones. The pressure isolation plug generally includes a body with a bore extending therethrough, a first disintegratable ball sized and positioned to restrict upward fluid flow through the bore, wherein the disintegratable ball disintegrates when exposed to wellbore conditions for a first amount of time. The plug also includes a second ball sized and positioned to restrict downward fluid flow through the bore.

    摘要: The present invention generally relates to a method and apparatus for sealing an annulus in a wellbore. In one aspect, the apparatus is an anchoring and sealing system for a downhole tool such as a bridge plug, packer, or frac-plug. The sealing system comprises of a sealing member disposed between a set of energizing rings, a set of expansion rings adjacent each cone, a set of support rings, and a set of slips. The components of the sealing system are arranged such that, when compressed, the sealing member may expand radially into contact with a casing. In another aspect, the apparatus the invention provides for an apparatus that is a downhole sealing tool.

    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.
