摘要： A technique provides a component actuation system in a space efficient form. A movable actuator member may be positioned within a corresponding housing in a manner which forms an annulus between the movable actuator member and the surrounding wall of the housing. A spring is located in the annulus and is designed such that the spring extends part way along a circumference of the actuator member to create an open annular region between circumferential ends of the spring. The open annular region provides space for a system related component without requiring additional longitudinal or radial space.

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.
摘要翻译：一种技术使得能够利用流量控制系统控制井眼中的流量。在一些情况下，流量控制系统可以包括挡板装置，隔离组件和致动组件。挡板装置可以构造成在打开和关闭状态之间移动时在15°至75°的近似角度范围内旋转。在一些情况下，接合构件可以包含成型端，其构造成在打开和控制挡板装置的关闭速率期间增加施加到挡板装置的力矩。挡板装置的角度范围的限制可以减小否则在闭合挡板装置时将对流量控制系统起作用的负载力。

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 and method 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.
