    摘要: A technique facilitates actuation of a variety of tools in many types of environments. The actuation technique employs a closed conduit, such as a closed tube, arranged in a curvilinear structure. By applying a differential pressure to the closed conduit, the curvature of the curvilinear structure is changed. This change can be used to actuate a corresponding tool between desired operational positions.

    摘要: A flow control device comprising a flapper retention device electrically activated to a hold position to retain the flapper in an open position in response to the operator being in a first position and the retention device electrically deactivated to a released position permitting movement of the flapper in response to the operator being in a second position. When the operator is in the first position, an end of the operator is located in the closure path of the flapper and in the second position the end of the operator is located out of the closure path.

    摘要: A technique enables control over flow in a wellbore with a flow control system. In some cases, the flow control system may comprise a flapper device, an isolation assembly, and an actuation assembly. The flapper device may be configured to rotate within an approximate angular range from 15° to 75° when shifting between an open and closed state. In some situations, the engaging member may contain a profiled end configured to increase the moment applied to the flapper device during opening and control the rate of closure of the flapper device. The limitation to the angular range of the flapper device may reduce the loading forces that would otherwise act against the flow control system upon closure of the flapper device.

    摘要: A technique enables control over flow in a wellbore with a flow control system. The flow control system combines a flow reduction mechanism with a flow control device, such as a valve. The flow reduction mechanism comprises a closure member which can be selectively moved between an unactuated and actuated position, allowing relatively greater flow through the flow control device in the unactuated position. The flow reduction mechanism actuates prior to or in conjunction with the flow control device to reduce flow and thus reduce the loading forces that would otherwise act against the flow control mechanism upon closure of the flow control device.

    摘要: A technique facilitates controlling flow in a wellbore with a simplified valve. The design of the valve also enables reduction in the overall length of the valve to improve spatial considerations. The valve comprises a valve component, e.g. a flapper, movable between a closed position and an open position. A flow tube is designed to selectively open the valve component with reduced travel, thus enabling a shortened flow tube. The short flow tube enables use of valve housings, springs, and other valve components having a reduced length.

    摘要: A technique facilitates prolonging the useful life of a subsurface valve without requiring replacement of the entire hydraulic chamber housing of the subsurface valve. A removable piston tube is provided and may be inserted into a valve housing of a subsurface valve. The removable piston tube is removably secured within a piston passage in the valve housing via a fastening mechanism. If necessary, the removable piston tube can be removed and replaced without requiring replacement of the overall housing.

    摘要: A system for use in a wellbore that includes a string comprising a housing. The housing comprises a valve including a valve seat having an inner channel and a flapper configured to pivot relative to the valve seat between a first position and a second position in which the inner channel is obstructed. A valve actuating device may be provided for selectively opening the valve and comprising a first hydraulic device. In addition, a retention device including a second hydraulic device may be provided and configured to selectively retain the flapper in the first position. In some cases, the first hydraulic device and the second hydraulic device may be driven by the same fluid source.
