摘要： An apparatus that is usable with a well includes an operator and a generator. The operator is disposed in the well and configured to respond to a differential pressure between hydraulically isolated zones of the well to produce mechanical motion. The generator is disposed in the well to convert the mechanical motion into electricity. A method that is usable with a well is provided including maintaining hydraulic isolation between a first and second zone of a well. While maintaining the hydraulic isolation, the method further includes producing a mechanical motion in response to a differential pressure between the first and second zones and generating electricity in response to the mechanical motion.

摘要： A choke that is usable with a well includes an inlet port and an outlet port. The choke also includes pressure drop stages between the inlet port and the outlet port. Each of the pressure drop stages is adapted to create part of an overall pressure differential between the inlet and outlet ports.

摘要： A technique facilitates controlling fluid flows, such as fluid flows in a downhole well zone or zones. A flow control valve is employed to control a fluid flow and is operationally linked with an injection valve. Actuation of the flow control valve is used to automatically actuate the injection valve between corresponding positions allowing or blocking fluid injection. Closing or opening of the flow control valve thus results in a desired corresponding action of the injection valve, such as blocking flow or allowing flow through the injection valve.

摘要： A hydraulic actuator is connected between a downhole tool and a hydraulic control line for operating the downhole tool through an actuation sequence. The hydraulic actuator comprises a valve shuttle section having an inlet port in connection with the hydraulic control line, a first function port and a second function port. The hydraulic actuator also has a shuttle movable between positions providing fluid communication between the inlet port and the first function port and the inlet port and the second function port. Additionally, the hydraulic actuator has a pilot assembly in fluid connection with the hydraulic control line and in operational connection with the shuttle. The pilot assembly is movable in response to an actuation cycle comprising applying pressure from the hydraulic control line and bleeding the pressure off.

摘要翻译： 一种技术有助于控制流体流动，例如在井下井区域或区域中的流体流动。 流量控制阀用于控制流体流动并且与注射阀可操作地连接。 流量控制阀的启动用于在允许或阻止流体注入的相应位置之间自动启动注射阀。 因此，流量控制阀的关闭或打开导致喷射阀所需的相应作用，例如堵塞流动或允许流过喷射阀。
