摘要： A method and apparatus for predictable downhole milling of a casing window having predetermined location, orientation, dimension and contour geometry. An elongate substantially rigid milling shaft has at least one casing window milling element in fixed relation therewith and has a pilot mill in articulated and rotary driven connection with the milling shaft. The milling shaft is in articulated and rotary driven connection with a rotary drive mechanism. The articulated connection of the pilot mill and milling shaft may incorporate an articulation control system to permit the pilot mill to be maintained substantially coaxial with the milling shaft so that its trajectory at a predetermined stage of window milling can be controlled by the milling shaft when positive guiding by a deflecting tool can no longer be ensured. The deflecting tool is adapted to be set within the well casing and defines an inclined pilot mill guide surface for guiding the pilot mill along a predetermined inclined trajectory for milling into the well casing. The deflecting tool incorporates a generally cylindrical bearing for guiding and providing rotational stabilization to the pilot mill during initial window milling to ensure the accuracy of the pilot bore being milled through the well casing and into the surrounding formation. During window milling the pilot mill guides the milling shaft so that the string mills of the milling shaft remove a portion of the pilot mill guide bearing and form a guide face of predetermined contour on the deflecting tool for guiding other tools through the casing window and into the lateral bore. The deflecting tool may be of tubular geometry so as to guide not only the pilot mill but also the string mill and may also receive the rotary drive motor for guiding and stabilizing thereof.

摘要： A method and apparatus for establishing connectivity of lateral branch liners to main well casings to achieve predictable and stable mechanical connectivity at the lateral junction of branch well bores to the main well bore to counter the problems of formation instability at the junction. After construction of a well having one or more lateral branches, a retrievable lateral branch template is located in the casing of a main well bore in positioned and oriented registry with a casing window that opens to a lined lateral branch. A retrievable lateral branch connector is then installed in assembly with the template to cooperatively define a production flow path having maximized mechanical integrity and optimized production flow in both the lateral bore and the main bore. The lateral branch template and connector provide the capability to selectively re-enter a lateral branch and to also hydraulically isolate the formation surrounding the junction from fluid circulating in both the lateral branch and the main well bore. Both the lateral branch template and the lateral branch connector are prefabricated and installed into the well by means of running and setting tools. Electrical power or hydraulic pressure conductors incorporated in the template and connector assembly may be used to provide for production operation and control of main and branch well bore production after installation. The equipment can be deployed in wells constructed with any inclination and orientation and can accommodate low or high dogleg severity at kick-off.

In one arrangement, one portion of the inductive coupler assembly is attached to a production tubing section and the other portion of the inductive coupler assembly is attached to a casing or other liner section. The production tubing inductive coupler portion is electrically connected to a cable over which electrical power and signals may be transmitted. Such power and signals are magnetically coupled to the inductive coupler portion in the casing or liner section and communicated to various electrical devices mounted outside the casing or liner section.

摘要： A well completion apparatus and method comprises a junction assembly having a template and a lateral branch connector engageable with the template to couple a main bore to a lateral branch bore. To improve inter-engagement characteristics of the template and connector, one arrangement of the junction assembly utilizes a continuous rail and groove inter-engagement mechanism. In another arrangement, a portion of the rail and groove inter-engagement mechanism is segmented instead of continuous. A method and apparatus is also provided in some arrangements to enable placement of intelligent completion devices in a lateral branch. Additionally, some junction assemblies comprise flow control mechanisms to control commingling, or not, of fluids from different regions in the well bore.

摘要： The present invention provides a tool for use in wellbores. The tool is operated by the wellbore hydrostatic pressure. The tool includes one or more devices that operate when a mechanical force is applied to such devices. The tool includes at least one atmospheric chamber. A setting member disposed in the tool is utilized to provide the mechanical force in response to the application of the hydrostatic pressure thereto. Prior to activating the tool, the setting member is locked or restrained in an inoperative position. To operate the device, the tool is placed at a suitable location in the wellbore. The atmospheric chamber is charged with the wellbore fluid, which releases the setting member from its restrained or locked position, subjecting the setting member to the wellbore hydrostatic pressure, thereby providing the mechanical force to operate at least one of the devices. A second atmospheric chamber may be provided that remains at the atmospheric pressure, but cooperates with the first chamber as it is charged with the wellbore fluid to operate a second setting member, which operates a second device. A sensor associated with the tool detects signals transmitted to the tool from a remote location. A control circuit in the tool receives the detected signals from the sensor and in response thereto operates an electrically-operated flow control device, thereby charging the chamber with the wellbore fluid.
