摘要： Methods and apparatus for forming multilateral wells and sealing the junction between the main well bore and a lateral well. In a first embodiment of the invention, a main well bore liner includes windows or openings formed in the liner. A drillable insert is positioned near the window for support when the lateral well is drilled. The window is also filled with a drillable material. A second embodiment of the invention uses inflatable casing packers which are inflated with cement to form junction having pressure integrity from the inside and the outside with a full opening lateral and a main bore restricted only by the inner diameter of the inflatable casing packers. A third embodiment of the invention uses a layered sealing sleeve at the opening of the lateral well. A tie back liner top mandrel is wedged through an opening in the layered sealing sleeve. The mandrel includes a flange, at the top and the interference fit between the flange and the opening in the sealing sleeve forms a hydraulic seal between the main well bore and the lateral well.

摘要： Expandable casing has an expandable slip used for completion of a mono-diameter wellbore. The expandable casing is run through the upper casing and has an upper end that overlaps a lower end to form a fluid flow path between the expandable casing and the upper casing. The operator expands the overlapping portion of the expandable casing to an intermediate position, causing the expandable slip to anchor the expandable casing to the upper causing without blocking the flow path. Cement is then pumped up around the outside of the expandable casing and wellbore fluid displaced by the cement and excess cement are permitted to flow through the fluid flow path and up the upper casing. After sufficient cement is in place, the expandable casing is further expanded, compressing the expandable slip into to the inner wall of the upper casing and sealing off the fluid flow path.

摘要： A releasable packer device and a method for selectively releasing a packer assembly from a set position in a wellbore. A packer assembly is described that incorporates a split body lock ring that is in ratcheting engagement wi th a central mandrel to secure the packer elements in a set position. In addition, there is a mechanical means for releasing the body lock ring from its locking position to an unlocked position. The body lock ring is released by radially expanding the ring by urging an axially-movable release sub with a releasing portion into contact with the body lock ring to unseat the ratcheting mechanism that retains the packer assembly in its set position.
