MULTIPLE ZONE DOWNHOLE INTELLIGENT FLOW CONTROL VALVE SYSTEMAND METHOD FOR CONTROLLING COMMINGLING OF FLOWS FROM MULTIPLE ZONES

摘要

Disclosed here is a production control system (10) having a series of nested tubular members (32, 34) including at least one axial flow channel and at least two annular flow channels. At least one valve (44, 46, 52) configured and positioned to control flow from each flow channel is provided. Further disclosed herein is a production apparatus having a series of nested tubular s connected to one another such that at least an axial flow channel and at lea st two annular flow channels are formed. A valve is associated with each of the flow channels and is configured and positioned to independently control flow from each of the flow channels. Further disclosed herein is a method for controlling commingling of flows from multiple zones. The method includes physically containing flows from different zones to individual concentric fl ow channels in a nested tubular arrangement and selectively commingling one or more of the flows by setting at least one valve associated with each flow channel to a closed position one of an infinite number of flow capable positions.
