    摘要: A retaining device for a threaded connection that is expanded holds the connection together to prevent leakage. In a two step thread the retention device is located between the steps and comprises a nose in a groove that holds aligned surfaces together for a metal to metal connection and allows for relative axial movement at the same time.

    摘要: A first, expandable casing member, in an unexpanded state, is provided with a lower axial end that has a radially expanded upset or recess shoe and a locating profile. The first casing member is run into a wellbore, expanded, and secured in place within the wellbore. A second expandable casing member is then provided in an unexpanded state and disposed into the wellbore through the first casing member using a running tool. The second casing member is located with respect to the first casing member and expanded using an expansion member carried by the running tool.

    摘要: A well having a minimum drift between or among strings is provided using strings that have a recessed segment and a hanging segment. The length of the recessed segment in the lower end of the upper string is substantially longer than the hanging segment of the lower string that is passed through it. The hanging segments define the drift dimension. In the event the lower string gets stuck in the open hole before it is fully advanced, the hanging segment of the lower string may still be in the recess of the upper string so that the drift dimension can be preserved. Preferably the recess segment is the substantial length of the tubular string apart from its hanging segment near its top end. One or more laterals can be extended through the recessed segments while retaining the drift dimension.

    摘要: A swage is made from segments that slide relatively to each other to go from a run in dimension to a maximum or built dimension when the segments move into alignment. The angle of inclination of the sliding axis between the members is less than the swaging angle for the pipe on the exterior of the segments so that once the segments are aligned and driven into a tubular for swaging they are precluded from extending into misalignment to clear an obstruction. In this manner a minimum drift is provided or the swage simply stalls. The swage in a tubular goes to the predetermined maximum dimension using the sliding surfaces that are at an angle to bear the radial reaction forces from the tubular more directly, thereby reducing the contact forces and the resulting friction. The edge connections reduce bending which can cause segment binding as the swage is built in the tubular.

    摘要: The tubular string to be expanded is run in on a running string. The swage assembly has a seal from the running string to the existing tubular and the top of the tubular string to be expanded also has a similar seal against the exiting tubular. Annulus pressure around the running string drives the swage assembly to support the expanded tubular to the exiting tubular and to continue expansion to the end of the tubular. Cementing then takes place followed by reconfiguring the swage assembly to engage the liner hanger seal with the result being a monobore connection in a single trip including the cementing.

    摘要: An expandable packer features a sealing element in an exterior recess that is straddled by projections or bumps. Upon expansion the bumps move out against the borehole wall as an anchor support. Optionally, the bumps may be covered with a sealing material and may be constructed to assist in their radial movement to the borehole wall as a result of expansion particularly if the mandrel is expanded in compression. The bumps are not necessarily expanded with the swage and their radial growth can be induced from longitudinal shrinkage resulting from radial expansion.

    摘要: An open hole packer uses mandrel expansion and a surrounding sealing element that can optionally have a swelling feature and further a seal enhancing feature of a ring with an internal taper to match an undercut on the mandrel exterior. As a swage progresses to the taper at the transition between the ring and the extending flat fingers, the fingers get plastically deformed in an outward radial direction to push out the sealing element. Shrinkage of the mandrel axially due to radial expansion brings a ring on the mandrel outer surface under the fingers to act as a support for the fingers against the seal which is pushed against the open hole. Mirror image orientations are envisioned to aid in retaining pressure differentials in opposed directions. Another external mandrel ring extends into the seal to keep its position during differential pressure loading.

    摘要: The expandable casing packing element systems for cased and open-hole wellbores include an expandable casing member having a sealing device comprising a sealing element disposed between at least two retainer rings. The retainer rings have flat cross-sections and the sealing element is forced radially outward by the expansion of the expandable casing against the two retainer rings such that the sealing element protrudes outwardly beyond the retainer rings and engages the wall of a wellbore in three locations. The retainer rings can also include flares that extend outwardly from the body of the expandable casing to which they are attached. As the expandable casing is expanded, the flares are forced inward to compress the sealing element which is then extruded radially outward through a gap between the two retainer rings to engage and seal off the wellbore.

    摘要: An expansion assembly is run into the well as the expandable liner is made up. A work string is tagged into the expansion assembly and run to depth. Pressure drives the swage to initially expand and move uphole with the attached work string until the liner is expanded to set at least one external packer. The balance of the expansion in the uphole direction is continued until the string is expanded into sealing support of a higher string in the wellbore and the variable swage comes out of the hole with the work string. A shoe is milled out and the process can be repeated.
