| 摘要 |
The present invention is a surface controlled gas lift valve designed for high flow rates and used in a subterranean well, comprising: a valve for sealable insertion in a mandrel, having a variable orifice which alternately permits, prohibits, or throttles fluid flow into the valve, and a detachable and/or remote actuator are disclosed. The valve can be actuated by an electro-mechanical actuating assembly while sensors can relay the position of the variable orifice to a panel on the surface. The orifice valve and the actuator while operatively connected, may be separately installed in or retrieved from by either wireline or coiled tubing intervention methods.
