    摘要： A subterranean well valve assembly includes a valve mounted within an annular housing which is actuated by an annular plunger co-axially mounted within the housing. The plunger is longitudinally shiftable to open the valve, in response to a fluid pressure signal. Within the housing, releasable latches are provided for engaging an annular groove, thereby temporarily locking the plunger in its lower position. The valve assembly also includes a permanent lock open mechanism comprising an annular locking mandrel, including a latch element. Longitudinal movement of the mandrel locks the mandrel in place, thereby interfering with subsequent retraction of the plunger from locked position.

    摘要： An apparatus to protect the mounting area of casing and a locating profile and optionally a sliding sleeve valve and a flow path from the outside of the valve to the annulus when subsequent attachment of an expanded liner is intended and the expanded liner is to be cemented in place. A barrier sleeve, nose, and outer sleeve define a sealed cavity having a loose incompressible material inside that covers the mounting location on the casing. A locating profile and an optional sliding sleeve valve and a flow path from the outside of the valve to the annulus can be provided. The cementing of the casing takes place through the barrier sleeve. After the cementing, the sleeve and nose are drilled out and the incompressible material is removed to the surface with the drill cuttings. A liner is inserted in the casing and is preferably expanded into sealing contact.

    摘要： A wet connect/disconnect arrangement is disclosed for a downhole system that allows installation of various tools and/or a string and subsequent electrical connection to the downhole system in a wet environment. Several embodiments are disclosed, all of which produce a clean, reliable connection. Exemplary embodiments include an upper section being mechanically and electrically joined to an intermediate section with electrical connectors for being joined at a lower section. The intermediate section further has auxiliary connectors that may be protected by a cover and remain unmated in a first connected application being therefore available for future use. The upper section may be removed leaving the intermediate section in place whereby the unmated connectors are available to rejoin a new upper section. Different types of connectors are also disclosed.

    摘要： The disclosure relates to a flapper type safety valve incorporating a pressure equalizing feature in the body of the flapper valve. A bypass aperture in the flapper valve communicates with a downwardly facing conical sealing surface. A conically shaped sealing plug is insertable in the bypass aperture and has a post portion projecting upwardly through such aperture. A diametral slot is provided in the top surface of the flapper valve body to mount a leaf spring which is secured to the upstanding post. An abutment element is also secured to the top end of the upstanding post and projects diametrically into the path of the actuating sleeve normally utilized to effect the opening of the flapper valve. The actuating sleeve thus contacts the abutment element prior to effecting any opening movement of the flapper valve and depresses the abutment element downwardly, against the bias of the leaf spring, to move the sealing plug downwardly and open the bypass aperture, thus equalizing pressure across the flapper valve body before any opening movement of the flapper valve body occurs.

    摘要： A method and an apparatus for setting the temporary lock-open mechanism incorporated in a safety valve employed in the subterranean well, the apparatus including an annular mandrel having an external, axially movable, radially expandable collet operated by an axially movable prong concentrically arranged within the mandrel housing.The temporary lock-open mechanism of the valve includes latch fingers which are adapted to engage the end of a plunger which opens the valve, a spring biased lock-open sleeve and release keys for holding the sleeve in a passive position.The valve is temporarily locked in an open position by introducing control line pressure into the valve for opening it and moving its lock-open mechanism to a position where the expandable collet of the apparatus can release keys that restrain the lock-open sleeve. The control line pressure is then bled off, thus allowing the spring biased lock-open sleeve to move to a position for camming the latch fingers into engagement with the end of the valve opening plunger.

    摘要： An apparatus to protect the mounting area of casing and a locating profile and optionally a sliding sleeve valve and a flow path from the outside of the valve to the annulus when subsequent attachment of an expanded liner is intended and the expanded liner is to be cemented in place. A barrier sleeve, nose, and outer sleeve define a sealed cavity having a loose incompressible material inside that covers the mounting location on the casing. A locating profile and an optional sliding sleeve valve and a flow path from the outside of the valve to the annulus can be provided. The cementing of the casing takes place through the barrier sleeve. After the cementing, the sleeve and nose are drilled out and the incompressible material is removed to the surface with the drill cuttings. A liner is inserted in the casing and is preferably expanded into sealing contact with the mounting location on the casing. After expansion a cement retainer positioned at the bottom of the expanded liner and the sliding sleeve located either above the mounting location of the liner in the casing shoe or in the liner below the mounted top section allow cement to be delivered outside the expanded liner and the displaced wellbore fluid to return into the casing through so that the liner can be cemented. The cement retainer can be delivered with either the liner or the expansion tools to allow expansion and cementing in a single trip. A shifting tool can be run on the expansion string to actuate the sliding sleeve and if necessary to allow for cement to be pumped from the drill string into the annulus through the sliding sleeve. The cement retainer can be milled out in a separate trip.
