Method and apparatus for selective injection or flow control with through-tubing operation capacity

Abstract

A downhole flow control device is provided for remotely controlling fluid flow of production or injection fluids, and may offer the capacity to pass wireline tools therethrough. In a broad aspect, the device may include: a body member having a first bore extending from a first end of the body member and through an extension member disposed within the body member, a second bore extending from a second end of the body member and into an annular space disposed about the extension member, a first valve seat disposed within the first bore, and at least one flow port in the extension member establishing fluid communication between the annular space and the first bore; and a first sleeve member remotely shiftable within the first bore, and having a second valve seat adapted for cooperable sealing engagement with the first valve seat to regulate fluid flow through the at least one flow port. The device may also include: a closure member disposed for movement between an open and a closed position to control fluid flow through the first bore; a second sleeve member remotely shiftable within the first bore to move the closure member between its open and closed positions; means for selectively controlling movement of the first sleeve member to regulate fluid flow through the at least one flow port; and a cone member for directing fluid flow into the annular space.
