    • A drill string and powered device system, comprising a drill string which comprises a plurality of drill pipe sections. It includes several conductive drill pipe sections, each conductive drill pipe section having a first end and a second end, and including a conductor. The conductor is connected to a first contact means at the first end and a corresponding second contact means at the second end. The drill string also has a powered tool having a first end and a second end corresponding to the first and second end of the drill pipe sections, including a contact means at the first end. The drill string is made up so that conductive drill pipe sections are connected in series above the powered tool such that there is a conductive path through the conductive drill pipe sections to provide power to the powered tool.
    • 钻柱和动力装置系统,包括钻柱,其包括多个钻管段。 它包括几个导电钻管段,每个导电钻管段具有第一端和第二端,并且包括导体。 导体在第一端连接到第一接触装置,在第二端连接到相应的第二接触装置。 钻柱还具有动力工具,其具有对应于钻管段的第一和第二端的第一端和第二端,包括在第一端的接触装置。 钻柱被制成使得导电钻管段在动力工具上串联连接,使得存在穿过导电钻管段的导电路径以向动力工具提供动力。

    • When drilling or completing an oil or gas well, it is often desirable to drill a borehole at an angle to the initial borehole. A process for deflecting a well tool towards the wall of a well bore comprises positioning within the well bore a radially expandable pipe designed to curve longitudinally when its diameter is expanded, expanding the diameter of the radially expandable pipe thereby causing the pipe to curve and passing the well tool through the curved pipe: The process is particularly suitable for through-tubing operations in which a lateral bore is initiated from a production well having within the well a smaller diameter production tubing ( 14 ) comprising (i) passing through the production tube ( 14 ) a radially expandable pipe ( 1 ) designed to curve longitudinally as its diameter is expanded, into a section of well bore ( 12 ) having a diameter greater than the diameter of the production tubing ( 14 ) (ii) expanding the diameter of the radially expandable pipe ( 1 ) thereby causing the pipe to curve, (iii) passing through the curved pipe a milling device or drill bit and (iv) milling the casing or drilling into the well bore wall.
