    摘要： An isolation container designed for use with a downhole electric pump assembly commonly used in oil and gas drilling and production operations is disclosed. The isolation container (100) has an annular housing with an axial inlet and outlet bore. A downhole electric pump assembly (104) is centrally located within the pressure isolation container. The downhole electric pump assembly includes an electric pump (108) positioned above and coupled to a motor seal section (107) which is positioned above and coupled to a centrifugal pump, thereby providing a means to power the centrifugal pump. A blind coupling (102) is positioned above the electric motor with a tubular member connected thereto and extending through the inlet of the isolation container. The tubular member connects to a tubing string (26) supplying fluid from the surface. The blind coupling has a plurality of radially disposed ports (116) to allow pressurised fluid from the surface to flow into the annulus (118) between the downhole electric pump and the isolation container. This fluid then flows to inlet ports (120) on the downhole electric pump. The pressure of the pressurised fluid is then boosted or increased by the operation of the downhole electric pump. The fluid is then discharged through a tubular member (36), which is sealed in the outlet bore of the pressure isolation container. The tubular member extends through a packer (38) positioned below the pressure isolation container and the boosted pressure fluid is injected into the subsurface formation. An electrical cable (44) from the surface supplies power to the electric motor and a check valve (110) is provided on the upper end of the pressure isolation container for releasing entrained air in the pressure isolation container.

    摘要： A wellbore system with a tubular string extending from an earth surface down into a wellbore in the earth, a packer system with a selectively settable packer element, and a disconnect located between an end of the tubular string and the packer system, the disconnect operable from the surface by imposing a downward force on the tubular string. In one aspect the packer system's packer element is a tension-set packer element. A wellbore disconnect with a top sub (122), a mandrel (126) having an upper end secured to the top sub and a portion below the upper end releasably secured with at least one releasable member (138) to a carrier member (136), the carrier member having apparatus (156) for selectively gripping the mandrel, the apparatus for selectively gripping the mandrel also selectively gripping a bottom sub (144) within which the mandrel is moveable, the at least one releasable member releasable in response to a downward force on the disconnect.

    摘要： In one aspect of the invention, tools are actuated or operated within a well by selectively expanding the tool wall. To actuate the tool, the tool wall (225) is urged outward past its elastic limits. The expanding wall physically unlocks a locking ring (280) which then ulocks a piston (260). Thereafter, hydraulic pressure difference are employed to move the piston to operate the downhole tool. In another aspect of the invention, a first piece of casing is joined to a second, larger diameter casing. By expanding the diameter of the first piece of casing into contact with the second piece of casing, the two are joined together. The joint is formed with helical formations in a manner that provides flow paths around the intersection of the two members for the passage of cement or other fluid.
