Abstract:
1. A well flow control system comprising: a tubular adapted to be disposed in a well to define a well annulus, wherein the tubular has an outer member defining an internal flow conduit, and wherein at least a portion of the outer member is permeable allowing fluid communication between the well annulus and the flow conduit; and a flow control apparatus disposed within the flow conduit of the tubular, wherein the flow control apparatus comprises at least one conduit-defining structural member and at least one chamber-defining structural member; wherein the at least one conduit-defining structural member is configured to divide the flow conduit into at least two flow control conduits; wherein the at least one chamber-defining structural members is configured to divide at least one of the at least two flow control conduits into at least two flow control chambers; wherein each of the at least two flow control chambers has at least one inlet and at least one outlet; wherein each of the at least one inlet and the at least one outlet is adapted to allow fluids to flow therethrough and to retain particles larger than a predetermined size.
