摘要： A wet connector for latchingly connecting an electric cable between surface equipment and a previously installed electrically powered well tool at a remote, downhole location in a well for transmitting electrical energy or signals thereto or therefrom. This wet connector comprises a male connector on the downhole well tool and a female connector on the electric cable. The female connector carries a non-conductive liquid which is expelled therefrom during mating with the male connector to wash and cleanse the electrical contacts of both the male and the female connectors. One form of the wet connector is released electrically (reverse polarity being used), and another form of the connector is released by tensioning and slackening the electric cable a predetermined plurality of times. Systems using such wet connectors are disclosed, as are methods for their use. The wet connector can be used in conjunction with an electric cable for installing certain tools in a well, especially where it is desirable to deposit such tools gently with no jarring.

摘要： A pumpdown system in which the pistons providing for movement of the train into and out of the well do not travel down into the tubing below the wellhead and are connected to tools through reach rods extending down into the tubing. The cathead effect resulting from working around the loop with pistons is minimized by guides which substantially center the pistons in the loop and in the preferred form by the use of straight sections of the loop.

摘要： A method and apparatus especially adapted for use with an injection well in which a valve controlled H-member interconnects the two tubings of a two tubing installation and landing nipples are attached to the lower legs of the H-member to receive expendable fluid control means, such as standing valves, in which pressure applied to one tubing to create a pressure differential will move the valve controlling the interconnection between the H-members to open position to permit TFL operations to be carried out in the well and thereafter pressure exerted on a ball supported on the valve member of the control valve for the H-member closes the control valve, and the ball passes through the control valve. The fluid control members in the landing nipples may be ejected either before or after closing of the valve in the H-member.

摘要： Disclosed is a rod-type lubricator for moving well equipment through a flow conductor. A piston controls movement of the lubricator rod. The rod includes an equipment handling segment and reach segments. As many reach segments as desired may be employed. The distance through which the well equipment may be moved is greater than the stroke of the piston. This abstract is neither intended to define the invention of the application which, of course, is measured by the claims, nor is it intended to limit the scope of the invention in any way.

摘要： A subsurface safety valve for use in wells, preferably adapted for placement in a tubing string, having a lock open mechanism for temporarily maintaining the safety valve in the open to flow position. The safety valve includes a closure device, such as a rotatable ball, located in the flow passage of the valve and is opened and closed by a biased operator tube. The operator tube is movable in response to hydraulic fluid conducted to the safety valve operating on a piston carried on the operator tube. A shiftable sleeve and collet is positioned above the operator tube and has a profile for receiving a shifting tool. When shifted, the collet and sleeve act on the operator tube to hold the valve in the open to flow position. The collet engages a recess on the bore wall of the safety valve upon shifting, and the sleeve moves behind the engaged collet head to prevent unlocking. The safety valve can be returned to operation by shifting the sleeve and collet to their original, normal position.

摘要： A sealing ring assembly is disclosed for use in sealing the annular gap between two concentric cylindrical members, one of the members having an annular groove and the other member having a surface opposed to the groove. Deformable seal material and a radially expansible-contractible non-deformable split retaining ring are located in the groove, the seal material engaging one surface of the retaining ring and the retaining ring being positioned on one of the sidewalls of the groove. The seal material and the retaining ring extend radially to the surface of the other cylindrical member, the retaining ring being sized to elastically compress against that surface. The surface of the retaining ring facing the seal material is beveled or chamfered along a portion or all of its width, the beveled surface extending inwardly to the inner edge of the retaining ring. Fluid pressure applied to the seal material deforms the seal material and causes the seal material to urge the outer edge of the retaining ring against the surface of the other cylindrical member. The seal material is deformed to press against the surface of the other cylindrical member to provide a primary seal. The inner edge of the retaining ring is, preferably, spaced from the inner wall of the groove and under pressure the seal material deforms and flows into the gap formed between the inner edge of the retaining ring and the inner wall of the groove to prevent leakage of fluid around the retaining ring.
