摘要： The invention relates to a barrier valve for creating a fluid tight barrier in a well during the installation of completion equipment. The barrier valve includes a housing having a longitudinal direction for being installed in a tubular string. A hinged curved, substantially circular valve flapper is disposed in the housing. The valve flapper has a normally closed position for forming a fluid tight barrier between the inlet side of the housing and the outlet side of the housing. The valve flapper is configured for forming a fluid tight barrier in two directions, i.e. both in an upstream direction and in a downstream direction. A pressure actuated valve flapper actuator is configured for bringing the valve flapper from the closed position to an open position after a predetermined number of pressure increases. Also described is a method for opening a fluid tight barrier valve in a well, as well as a tubular part having a zigzag recess.

摘要： Certain aspects and embodiments of the present invention are directed to a dual closure system disposed within a wellbore and capable of preventing the production of fluids from a fluid-producing formation to the surface. The dual closure system can include a passive closure mechanism and a subsurface safety valve coupled to an electric submersible pump positioned within a passageway defined by the tubing string. The passive closure mechanism and the subsurface safety valve can prevent production of fluid in the absence of the subsurface safety valve. The subsurface safety valve can be positioned within a passageway defined by a tubing string such that the subsurface safety valve can apply force to the passive closure mechanism. The force applied to the passive closure mechanism can maintain the passive closure mechanism in an open position, allowing movement of fluid to the surface in the presence of the active closure mechanism.

摘要： A valve device and associated methods of selectively communicating between an interior and an exterior of a tubular string. A valve device includes an openable and closable flow path for selectively permitting and preventing flow between an interior and exterior of the valve device, and a lock assembly which prevents the flow path from being opened greater than a predetermined number of times. A method of testing at least one annular seal in an annulus formed between a tubular string and a wellbore wall includes the steps of : sealingly engaging the annular seal to thereby prevent flow through the annulus across the annular seal; and applying a pressure differential across the annular seal to thereby test the annular seal, the pressure differential being applied via a valve device interconnected in the tubular string.
