    • A downhole apparatus having a radially expanding portion and a support structure are described. The support structure comprises an attachment means for coupling to the apparatus and a support portion configured to be deployed from a first unexpanded condition to a second expanded condition by expansion of the apparatus. In one aspect of the invention, the downhole apparatus is expanded by exposing the swellable material to at least one predetermined fluid, and the support structure abuts the swellable material in its expanded form. A method of use and its application to a well packer, a hanging member, an anchor and a centralising apparatus are described.
    • 井下装置(10),例如中央控制器,包括在与至少一种预定流体接触时膨胀的可膨胀材料(12)。 在本发明的第一方面,扶正器包括主体和从主体直立的多个结构(22)。 在另一方面,一种井下装置包括通孔(11),所述通孔构造成接收管状,可膨胀构件以及与所述可膨胀构件一体形成的刚性组件。 刚性组件为使用中的设备提供了支架。 另一方面,在可膨胀构件膨胀之前,井下装置具有第一状态,其中刚性组件限定装置的最大外径。 在可膨胀构件膨胀之后的第二状态下,可膨胀构件限定装置的最大外径。 在优选实施例中,刚性组件被设计成在轴向或径向载荷下挠曲或变形。

    • 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.
    • 多分支井的和改进的多分支井结构由设置通过主井的侧壁镗位于主井筒(110)内的规定位置的分流(332)并在主井流导体(120)规定的方位作 流导体(120)和进入围绕主井流导体(120)的材料(112),所述镗创建具有在侧壁的特定形状,分流器的取向的窗口(324)(332)确定的采矿的横向位置 在主井流导体(120),一个侧井眼(150),从而形成在所述材料,并从主井孔(110)延伸,并且与一个衬垫衬在横向井筒(150)(340)的窗口的 具有接口端(342)的衬垫,所述接口端为angepasst以接触在侧壁上的窗口(342)的周边,并且横向井筒(150)内的适当位置固井衬垫(340)。 固井的步骤创建窗口的周边和衬垫(340)的接口端(342)之间的压力轴承密封。 该方法允许多个分支井筒将被接合到主井筒和提供用于主要和侧向井眼,关节的承压密封之间的连通性,以允许其一个或更多个井筒或部分的选择性分离和返工或其他目的的后续井筒访问 ,
