摘要： A subsurface safety valve for controlling fluid flow in a well bore. In one embodiment, the subsurface safety valve includes a tubular member having a longitudinal bore extending therethrough, a curved flapper removably connected to the tubular member. The curved flapper is configured to pivot against the tubular member between an open position and a closed position. The subsurface safety valve further includes a hard seat positioned inside the tubular member, in which the hard seat defines a seating surface configured to receive a sealing surface defined on a bottom periphery portion of the curved flapper to form a sealing interface having a slope that varies along the sealing interface.

摘要： An integral multistage safety valve is designed to provide a second level of protection should a first stage fail. The valve may be used in oil and/or gas wells. The interior portion of the multiphase safety valve is designed so as to reduce turbulence and pressure loss through the valve when the valve is in an open position. The valves may be independently operable, or operable with a single control line. The multi-stage valve reduces the number of body joints required to construct two identical valves thereby reducing cost and potential leak paths and increasing reliability of the system.

摘要： A lockout tool dimensioned to be received within a housing of a subsurface safety valve (SSV). The lockout tool generally comprises an elongated housing, and an expander mandrel slidably received within the housing. Together, the elongated housing and expander mandrel are run into the wellbore and landed into the housing of the SSV such that the end of the expander mandrel opens the flapper valve. A portion of the lookout tool housing shoulders against the flow tube in the SSV to drive the flow tube downward, thereby maintaining the flapper of the SSV in its open position. As the expander mandrel moves downward through the hard scat of the SSV, the mandrel engages the flow tube and expands it against the hard seat. In this manner, the flow tube is expanded into permanent, frictional engagement with the hard seat. This, in turn, looks the flapper member of the SSV in its open position.

The intermediate portion is positioned between the production tubing elevation and the flow line elevation and has an axial dimension configured to substantially maintain the axial dimension between the elevations. The intermediate portion has first and second shut-off valves for closing fluid communication of the axial bore. A hanger is positioned in the axial bore of the intermediate portion between the first and second shut-off valves. The hanger defines a bore and a port. The port communicates a side of the hanger with the lower end of the hanger. The coil tubing attaches to the port at the lower end of the hanger, and the port at the side of the hanger communicates with the feed line of the intermediate portion.

摘要： An equalizing subsurface safety valve for controlling fluid flow in a well conduit has a tubular body member with a longitudinal bore extending therethrough, and a flapper hingably connected within the tubular body member to alternately permit and prevent fluid flow through the longitudinal bore. The flapper is biased by a spring to a normally closed position to prevent fluid flow through the longitudinal bore. Surface controlled mechanisms are provided to control the opening of the flapper. A fluid passage is provided for fluid communication between the longitudinal bore adjacent a first side of the flapper when the flapper is in a closed position and a second side of the closed flapper. A valve closure member is mounted across the fluid passage adjacent the first side of the flapper and is movable along an axis generally transverse to the longitudinal bore. The valve closure member is contained so that it is prevented from possibly falling into the well. A spring contained within the fluid passage biases the valve closure member against a sealing surface formed within the tubular body. A fluid diverting passage is provided within the valve closure member to prevent an initial fluid flow through the fluid passage from contacting and eroding the sealing surface.
