    摘要： A sliding side door assembly (10) for use in a well bore having a side bore. The assembly (10) comprises a housing (12) having a generally tubular shape defining a central axis (X). A side port (28) is formed in the housing (12), and a ball seat (30) is positioned in the housing (12) adjacent the side port (28). A door subassembly (14) is operatively engaged with the housing (12) adjacent the side port (28) and includes a translating sleeve (34) positioned within the housing (12) and a ball sealing member (36) adapted to engage the ball seat (30) of the housing (12). A ball port (40) is formed through the ball sealing member (36). A cooperatively engaged helical track (42) and follower member (44) are provided for translating a driving movement along the central axis (X) through the translating sleeve (34) to a rotational movement of the ball sealing member (36) about the central axis (X). Driving movements acting on the door subassembly (14) can be provided by a standard shifting tool (46). Thus, a first driving movement acting on the door subassembly (14) in a first axial direction along the central axis (X) causes the translating sleeve (34) to rotate the ball sealing member (36) such that the ball port (40) moves into overlapping alignment with the side port (28), thereby opening the side port (28). Similarly, a second driving movement acting on the door subassembly (14) in a second axial direction along the central axis (X) causes the translating sleeve (34) to rotate the ball sealing member (36) such that the ball port (40) moves out of overlapping alignment with the side port (28), thereby closing the side port (28).

    摘要： Multilateral wells and improved multilateral well structures are made by setting a diverter (332) at a prescribed position and a prescribed orientation in a main well flow conductor (120) located within a main wellbore (110), boring through a sidewall of the main well flow conductor (120) and into a material (112) surrounding the main well flow conductor (120), the boring creating a window (324) having a particular shape in the sidewall, the orientation of the diverter (332) determining a lateral position of the window in the main well flow conductor (120), a lateral wellbore (150) thereby being formed in the material and extending from the main wellbore (110), and lining the lateral wellbore (150) with a liner (340), the liner having an interface end (342), the interface end being adapted to contact a periphery of the window (342) in the sidewall, and cementing the liner (340) in place within the lateral wellbore (150). The step of cementing creates a pressure-bearing seal between the periphery of the window and the interface end (342) of the liner (340). The method allows multiple lateral wellbores to be joined to the main wellbore and provides for connectivity among main and lateral wellbores, pressure-bearing sealing of joints to allow selective isolation of one or more wellbores or portions thereof and subsequent wellbore access for rework or other purposes.

    摘要： Multilateral wells and improved multilateral well structures are made by setting a diverter (332) at a prescribed position and a prescribed orientation in a main well flow conductor (120) located within a main wellbore (110), boring through a sidewall of the main well flow conductor (120) and into a material (112) surrounding the main well flow conductor (120). Here, it comprises the step of setting a preformed window member having a preformed window of a prescribed shape formed therein into said main well flow conductor. Therefore, rather than relying on the drilling tool to form a window having the prescribed shape, a member having a preformed window is lowered into place and the interface end of the liner is cemented thereto.

    摘要： A sliding side door assembly (10) for use in a well bore having a side bore. The assembly (10) comprises a housing (12) having a generally tubular shape defining a central axis (X). A side port (28) is formed in the housing (12), and a ball seat (30) is positioned in the housing (12) adjacent the side port (28). A door subassembly (14) is operatively engaged with the housing (12) adjacent the side port (28) and includes a translating sleeve (34) positioned within the housing (12) and a ball sealing member (36) adapted to engage the ball seat (30) of the housing (12). A ball port (40) is formed through the ball sealing member (36). A cooperatively engaged helical track (42) and follower member (44) are provided for translating a driving movement along the central axis (X) through the translating sleeve (34) to a rotational movement of the ball sealing member (36) about the central axis (X). Driving movements acting on the door subassembly (14) can be provided by a standard shifting tool (46).
