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.
摘要翻译： 本发明的某些方面和实施例涉及一种设置在井孔内并能够防止流体从流体产生地层产生到表面的双闭合系统。 双闭合系统可以包括被动闭合机构和与位于由管柱限定的通道内的电潜泵连接的地下安全阀。 被动闭合机构和地下安全阀可以防止在没有地下安全阀的情况下生产流体。 地下安全阀可以定位在由油管柱限定的通道内，使得地下安全阀可以向被动闭合机构施加力。 施加到被动闭合机构的力可以将被动闭合机构保持在打开位置，允许流体在主动闭合机构的存在下移动到表面。

摘要： An actuation assembly (100, 300) for actuating a downhole tool (200) having a tool housing (202) and an actuation member (208). The actuation assembly (100, 300) includes a downhole power unit (100) and a stroke extender (300). A power unit housing (150) is operably associated with an extender housing (302). A moveable shaft (130) of the power unit (100) is operably associated with an extender mandrel (304). The extender housing (302) is operably associated with the tool housing (202) and the actuation member (208). The extender mandrel (304) is operably associated with the actuation member (208) such that oscillatory movement of the moveable shaft (130) relative to the power unit housing (150) causes oscillatory movement of the extender mandrel (304) relative to the extender housing (302) which causes progressive movement in one direction of the actuation member (208) relative to the tool housing (202), thereby actuating the downhole tool (200).

摘要： Certain aspects and features are directed to an electric subsurface safety valve including an integrated communications system that can be disposed in a wellbore. The electric subsurface safety valve can include a body adapted to be coupled to a cable, a communications system disposed in the body, and a closure mechanism. The body can be disposed within the wellbore. The communications system can include one or more transceiving devices and a processing device. The transceiving devices can communicate signals via the cable to a rig at the surface and can wirelessly communicate signals to target tool in the well system. The processing device can process signals received by the one or more transceiving devices for communication via the cable. The closure mechanism can be positioned in a passageway defined by the wellbore and can control a flow of fluid to through the passageway.

摘要： A safety valve can be disposed in a wellbore that is through a fluid-producing formation. The safety valve can include a flow tube that is allowed to move at least partially independent, or free, from a piston assembly to avoid negative effects from forces on the flow tube from a closing assembly, such as one including a flapper. For example, the flow tube may not be required to be rigidly connected to a piston assembly such that the flow tube can move more than the piston assembly moves.
