摘要： A plug is provided which is specially adapted for statically setting a plug portion within an internal profile formed in a wellhead. In an illustrated preferred embodiment, the plug portion is set by application of fluid pressure to a running tool portion. When set in. the profile, the plug portion is secured statically relative to the profile, thereby permitting advantageous utilization of a metal-to-metal seal on the plug portion. The plug portion includes features which maintain its set configuration in the profile. The running tool portion includes multiple pistons which enhance operation of the running tool portion. A disclosed verification tool provides an indication that the plug portion has been properly set.

摘要： The flapper valve assembly can be used in series to provide collapsible closures in a drill pipe. Thus, when work strings are withdrawn through the flapper valve, it will close in a conventional manner. However, when the work string must be reinserted through the closed flapper, a collar holding the flapper in its closed position can be sheared from its position within the assembly housing.

摘要： A valve employing a coupling disk to rotate the valve member so that rotative force is applied to the valve member in a direction away from the seat during opening of the valve and/or in a direction toward the seat during closing of the valve. Closing force is provided by a spring in a dome chamber and a gas charge in the dome chamber. A float valve controls fluid entry into the dome chamber to trap the gas charge therein while permitting the introduction of liquid from a balance-closure assist line to increase the pressure of the gas charge and assist in closing the valve member.

摘要： A surface controlled subsurface safety valve for use in a well tubing string including a valve closure member, an operator tube for opening the valve closure member, a small diameter offset piston to move the operator tube in response to control fluid pressure conducted from the well surface, and a spring biasing the operator tube to a position closing the valve. A bearing assembly mounted on the operator tube minimizes eccentric and torsional loading of the operator tube by the piston and spring. The operator tube also has multiple flow paths and barriers to prevent accumulation of debris from well fluids within the safety valve. The safety valve has metal-to-metal sealing systems to improve valve life under harsh downhole well environments.

摘要： A system and method for communicating hydraulic control to a wireline retrievable downhole device (112) are disclosed. The system utilizes a tubing retrievable downhole device (50) having a hydraulic chamber (70). A radial cutting tool (104) is selectively located within the tubing retrievable downhole device (50) to cut a fluid passageway (110) between the hydraulic chamber (70) and the interior of the tubing retrievable downhole device (50). Thereafter, when the wireline retrievable downhole device (112) is positioned within the tubing retrievable downhole device (50), hydraulic control is communicated to the wireline retrievable downhole device (50) through the fluid passageway (110) to actuate the wireline retrievable downhole device (50).

摘要： A linear indexing apparatus and associated methods of using same provide convenient operation of tools in a subterranean wellbore. In a preferred embodiment, a linear indexing apparatus has an outer tubular housing and a tubular mandrel axially slidably disposed within the housing. Two sets of slips are utilized to incrementally displace the mandrel relative to the housing. A piston associated with one of the sets of slips permits the mandrel to be incrementally indexed in response to a series of repeated applications of a predetermined differential pressure.

摘要： A subsurface safety valve has a valve seat and an upwardly closing flapper plate whose sealing surfaces each have a matched spherical radius of curvature. The sealing surface of the valve seat is a concave spherical segment and the sealing surface of the flapper plate is a convex spherical segment. The matching spherical surfaces are lapped together to provide a metal-to-metal seal along the interface between the nested convex and concave sealing surfaces. This permits angular displacement of the flapper plate relative to the valve seat without interrupting positive sealing engagement. The concave spherical seating surface of the safety valve seat will tolerate a limited amount of misalignment of the flapper plate which sometimes occurs during operation of the safety valve under high flow rate, high differential pressure conditions.
