    摘要: A method and apparatus for replacing a defective downhole well safety valve of the full bore type by a wireline valve sealably insertable in the bore of the housing for the defective valve by wireline and operating the wireline inserted safety valve by fluid pressure supplied through an existing control fluid passage provided in the original safety valve housing. An internally projecting integral protuberance is provided in the bore of the original safety valve housing and a connecting fluid conduit is provided between the interior of the protuberance and the existing control fluid passage. A cutting tool is mounted on an axially shiftable sleeve disposed immediately above the protuberance. The axially shiftable sleeve is manipulated by an auxiliary tool temporarily inserted in the bore of the original valve housing and causing the cutting tool to remove the protuberance and thus establish fluid communication for the control fluid with the internal bore of the original safety valve housing. The insertion of a conventional in-tubing safety valve apparatus will permit such apparatus to be operated by control fluid pressure supplied through the opening provided by the severed or removed protuberance.

    摘要: A subsurface control fluid pressure actuated well safety valve employs one or more spindles attached to the valve housing and spindle sleeves attached to a shiftable actuating flow tube. The spindles and spindle sleeves are positioned between the valve housing and the flow tube and a change in the pressure force acting on the spindle and on the spindle sleeve will result in relative movement of the spindle sleeve with respect to the spindle to cause the flow tube actuator to shift and open a fluid transmission conduit.

    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: 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 electronic key comprises a first binary counter and a first multiplexeror pulse code modulating a uniform clock pulse train to produce a first coded pulse train modulated with a given code. The key is connected to an electronic lock comprising: a second binary counter and a second multiplexer for pulse code modulating the same clock pulse train to produce a second coded pulse train modulated with the same code; an EXCLUSIVE-OR gate to which said first and second multiplexers are connected; a first NAND gate having one input connected to the output of the EXCLUSIVE-OR gate; a flip-flop or a binary counter having its clock input connected to the output of the NAND gate and an inital logical ONE output connected to a second input of the NAND gate; a second NAND gate having one input connected to the output of the flip-flop or counter and another input connected to the output of the second multiplexer; and a binary output counter having its clock input connected to the output of the second NAND gate. The output of the lock is taken from one of the counting outputs of the output counter.
