摘要： Assemblies that can be disposed in a subterranean bore are described. Certain assemblies can be used to orient a second pipe with respect to a first pipe in a bore. A second pipe can be rotationally oriented without breaking one or more control lines that may be associated or included with the second pipe by using a tool that orients the second pipe as the second pipe is moved toward a surface of the bore. In some embodiments, assemblies can be used to orient multiple portions of the second pipe with respect to multiple windows of the first pipe. The first pipe may be a casing string and the second pipe may be a tubing string.

摘要： A self-locating reentry system is provided to allow reliable reentry from a primary wellbore into one or more secondary wellbores. The reentry system may include one or more self-locating assemblies which may be engaged with selected portions of a lateral opening disposed between the primary wellbore and a respective secondary wellbore. Each self-locating assembly and respective key or lug cooperate with each other to provide optimum location and alignment relative to the lateral opening for communication of well tools and smaller diameter tubing strings between the primary wellbore and the associated secondary wellbore. A retaining mechanism is preferably provided to maintain the locator lug or key in its first retracted position until the reentry system is at a desired downhole location relative to the selected lateral opening.

摘要： A well has a vertical casing with a window, and a lateral wellbore which communicates with the window, and which may have a casing or liner. A window assembly aligned with the window has respective passageways for first and second tubing strings, and has a concave surface for deflecting the first tubing string out into the lateral wellbore. The passageway for the second tubing string has a portion which is inclined at a very small angle with respect to a vertical centerline of the vertical casing. As the first tubing string is run into the vertical casing, a rotational locator is releasably coupled thereto by a soft release coupling mechanism. After the locator effects rotational orientation, the coupling mechanism is released and then permits the first tubing string to move therepast without damage. A seal assembly on the first tubing string is covered by a protective sleeve as it is inserted into the well, and exits the protective sleeve after entering the lateral wellbore.

摘要： An improved tubing exit whipstock and tools for installing and retrieving the whipstock are provided for directing movement of well tools from a first wellbore to a second wellbore extending therefrom. The tubing exit whipstock may include a generally cylindrical deflector body with a longitudinal passageway extending therethrough. The deflector body may also include a tapered surface for deflecting well tools from the first wellbore to the second wellbore. In one embodiment of the present invention, a mechanical connector may be provided for attaching the deflector body to an orienting and locking device to releasably install the whipstock at a selected downhole location. In another embodiment, a first fishing neck profile may be provided within the longitudinal passageway to provide means for releasably coupling the deflector body with a running tool for installing the tubing exit whipstock at a selected downhole location within the first wellbore. In yet another embodiment, the fishing neck may provide means for releasably coupling the deflector body with a pulling tool for removing the tubing exit whipstock from the selected downhole location within the first wellbore.

摘要： The present disclosure addressed apparatus and methods for forming an annular isolator in a borehole after installation of production tubing. Annular seal means are carried in or on production tubing as it is run into a borehole. In conjunction with expansion of the tubing, the seal is deployed to form an annular isolator. An inflatable element carried on the tubing may be inflated with a fluid carried in the tubing and forced into the inflatable element during expansion of the tubing. Reactive chemicals may be carried in the tubing and injected into the annulus to react with each other and ambient fluids to increase in volume and harden into an annular seal. An elastomeric sleeve, ring or band carried on the tubing may be expanded into contact with a borehole wall and may have its radial dimension increased in conjunction with tubing expansion to form an annular isolator.

摘要： A releasable no-go tool and associated methods provide enhanced capabilities in positioning an item of equipment in a wellbore. In a described embodiment, a releasable no-go tool includes a circumferentially continuous key which is radially outwardly displaced by a series of pistons. In use, the tool is interconnected in a tubing string, which is lowered into a casing string in a wellbore. The casing string has a nipple interconnected therein, the nipple having an internal profile. The tool is positioned below the nipple, pressure is applied to the tubing string to extend the key, and the tubing string is raised to thereby engage the key with the profile.

摘要： A method of installing a wellbore junction assembly in a well can include inserting a tubular string into a deflector, and opening a flow control device in response to the inserting. A well system can include a deflector positioned at an intersection between at least three wellbore sections, and a tubular string connector having at least two tubular strings connected to an end thereof, one tubular string being received in the deflector and engaged with a flow control device positioned in a wellbore section, and another tubular string being received in another wellbore section. Another method of installing a wellbore junction assembly in a well can include inserting a tubular string into a deflector positioned at a wellbore intersection, then sealingly engaging the tubular string, and then opening a flow control device in response to the inserting.
