发明名称 Fluid flow control device and method for use of same
摘要 A fluid flow control device ( 60 ) for use in a wellbore to control the inflow of production fluids comprises a sand control screen ( 62 ) having a base pipe ( 64 ) with a first set of openings ( 66 ) that allows the production fluids to flow therethrough and a sleeve ( 74 ) coaxially disposed adjacent to the base pipe ( 64 ). The sleeve ( 74 ) has a second set of openings ( 76 ) that allows the production fluids to flow therethrough. The sleeve ( 74 ) is selectively positionable relative to the base pipe ( 64 ) such that a pressure drop in the production fluids is selectively controllable by adjusting an alignment of the first set of openings ( 66 ) relative to the second set of openings ( 76 ).
