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.
