    摘要: A structure is positioned on the outer surface of a casing or liner to enable cutting the casing in substantially any azimuth over a given length of casing without damaging the structure. After placing the casing in a wellbore, the position of the structure on the casing may be determined with reference to an orienting slot in an indexing coupling. Thereafter, a non-colliding region on the casing may be identified for cutting the casing.

    摘要: A method and apparatus that allows communications of electrical power and signaling from downhole component to another downhole component employs an inductive coupler assembly. 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. In other arrangements, inductive coupler assemblies may be used to couple electrical power and signals from the main bore to components in lateral branches of a multilateral well.

    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: A well completion system includes a branching sub disposed within a wellbore. The branching sub includes a branching chamber and a plurality of branching outlet members. The branching outlet members have a retracted state in which an effective diameter of the branching outlet members is less than or equal to a diameter of the branching chamber. The branching outlet members have an expanded state in which the outlet members extend beyond the diameter of the branching chamber. The system further includes a manifold located above the branching outlet members, the manifold in fluid communication with the branching outlet members.

    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.
