    摘要: The present invention relates to art improved method for multilateral completion and cementing (e.g. sealing) the juncture between primary and lateral wellbores. The completion method of the present invention addresses the issue of cementation and sealing of junctures between vertical and lateral wellbores. It is desirable to have the ability to re-enter each lateral wellbore as well as maintain the option to perform any function that could be done in a single wellbore. For this reason, cemented and sealed lateral wellbores are desirable so that normal isolation, stimulation or any other operation can be achieved. The method allows sealing and reworking of either wellbores with single laterals or multiple laterals and provides safe durable junctions therebetween. The method of this invention utilizes a "hook" liner hanger system.

    摘要: The invention relates to actuation of a downhole tool by hydraulic forces in a structure that does not employ lateral openings through the wall of the tool. By a variety of mechanisms, the tool wall is urged to flex preferably within its elastic limits. The wall flexing either signals a sensor which senses such motion to create a corresponding signal which can unlock a piston. Thereafter, hydraulic pressure differences are employed to move the piston to operate the downhole tool.

    摘要: An expandable slip ring is used to secure attachment of an expanded tubular to a surrounding tubular. It features elongated generally axially oriented openings separated by narrow segments. As a swage is advanced within a tubular that has the slip ring outside it the narrow segments or tabs expand and can break but the ring is still held to its shape as the expansion progresses due to the integrity of other tabs that can subsequently break as the swage advances within the tubular that is surrounded by the slip ring. The integrity of the slip ring is enhanced for storage and run in while the expansion characteristics are more uniform as the ring retains some structural integrity during much of the expansion process.

    摘要: An expandable tubular pin and box connection is described having a feature of trapping the pin nose after preferably deforming the pin nose plastically in an outward direction away from the longitudinal axis of the connection. The box end is held away from the pin wall before expansion so that its tendency to curl inwardly upon expansion causes it to bend against the pin wall for sealing with it. The thread profile is also optimized to reduce flank separation as a result of expansion.

    摘要: A multilateral junction comprises a primary leg and one or more lateral legs. Each end of the primary leg and each lateral leg has an inflatable element therein. A method for installing a multilateral junction includes running a deformed junction to depth and serially or collectively inflating an inflatable element in each leg of said junction to reform said junction.

    摘要: A ball dropping assembly is shown of the type which is connected in a string of pipe for dropping a ball in the pipe string. A main body is mounted on the pipe. The main body has an interior bore which communicates with the interior of the pipe. A cam housing is received within the main body bore and has a ball receiving recess formed in the interior thereof. A ball dropping can is rotatably received within the cam housing. The can has partially cut-away sidewalls which form a camming surface for the ball. A retaining nut engages and seals the cam housing and can within the body whereby rotation of the can with respect to the cam housing houses the camming surface to contact the ball to thereby eject the ball from the ball receiving recess into the interior of the pipe without opening the assembly to the atmosphere.

    摘要: Disclosed are apparatus and method of closing a conduit against fluid flow in at least one longitudinal sense, and selectively disengaging and reengaging the closure mechanism without removing the closure mechanism from the conduit. In a particular embodiment, a valve assembly may be selectively anchored and sealed to a well packer, or disengaged therefrom. The valve assembly is manipulated by an operating tool to which the valve assembly is anchored in the well when the valve assembly is disengaged from the packer.
