    摘要: A method of supporting a tubular within a bore including the steps of at least partially expanding a sleeve into contact with a bore wall to secure the sleeve within the bore, and engaging a portion of the tubular to be supported with the sleeve to provide hanging support for the tubular. In one embodiment, the sleeve is expanded by engagement with the tubular. In another embodiment, the sleeve is initially expanded using a roller expansion tool, with further expansion being achieved by way of engagement of the tubular with the sleeve. An apparatus for supporting a tubular within a bore in one embodiment comprises an expandable sleeve having a first surface and being adapted to be expanded into contact with a bore wall, and a conical portion adapted to be coupled to a tubular, the conical portion having a second surface adapted to engage the first surface of the sleeve.

    摘要: An expander tool includes segments capable of deflecting inward in response to a restriction encountered while expanding a tubular downhole. The expander tool includes an inner mandrel having a tapered surface about its outside diameter, the segments disposed around the inner mandrel with corresponding tapered surfaces in contact with the tapered surface of the inner mandrel and a compression sleeve disposed around the inner mandrel. A compressive load on the compression sleeve applies a preload force biasing the segments to a raised position on the tapered surface and hence an extended position. This preload enables expansion of the tubular with the segments in the extended position. Upon reaching the restriction, an increased pull force on the expander tool forces the segments down the tapered surface of the inner mandrel against the bias of the preload to a retracted position such that the expander tool assumes a smaller maximum outer diameter.

    摘要: A method and apparatus for a wellbore expandable connection is disclosed. The connection may include a pin having an outward tapered threaded section and a box having an inward tapered threaded section. The threaded sections form a connection of a predetermined integrity upon make-up. An embodiment of the connection includes at least one interface area of the connection that lacks intimate contact between the pin and the box upon initial make-up. Either the box or the pin, or both, have a friction surface at the interface area. Radial expansion of the connection places the pin in contact with the box at the interface area such that the friction surface between them locks the connection. In one embodiment, the connection includes a receptacle profiled in a portion of the box that provides space within the connection for material that extrudes from the pin during expansion of the connection.

    摘要: A method for cleaning and/or altering an inside surface and shape of a tubular is disclosed. The method includes placing a surface finishing tool in the tubular, energizing the surface finishing tool, and causing extendable assemblies therein to extend radially to contact an inside diameter of the tubular. Moving the surface finishing tool axially and/or rotationally while the extended members are in contact with the inside diameter of the tubular cleans debris from the inside surface of the tubular. In another aspect of the invention, the tool burnishes the inside diameter of the tubular, thereby altering the surface characteristics and rounding the tubular.

    摘要: In one embodiment, a method for drilling a wellbore includes an act of drilling the wellbore by injecting drilling fluid through a tubular string disposed in the wellbore, the tubular string comprising a drill bit disposed on a bottom thereof. The drilling fluid exits the drill bit and carries cuttings from the drill bit. The drilling fluid and cuttings (returns) flow to a surface of the wellbore via an annulus defined by an outer surface of the tubular string and an inner surface of the wellbore. The method further includes an act performed while drilling the wellbore of measuring a first annulus pressure (FAP) using a pressure sensor attached to a casing string hung from a wellhead of the wellbore. The method further includes an act performed while drilling the wellbore of controlling a second annulus pressure (SAP) exerted on a formation exposed to the annulus.
