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. To facilitate building the swage in a tubular to the predetermined maximum dimension, the sliding surfaces are configured 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 are also configured to reduce bending which can cause segment binding as the swage is built in the tubular.

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： 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 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.
