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 adapted to be 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 three flow control conduits; wherein the at least one chamber-defining structural members is configured to divide at least two of the at least three 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; and wherein at least one of the at least three flow control conduits is in fluid communication with the well annulus only through one or more of the flow control chambers.
