downhole fluid flow control system, downhole flow control sieve and downhole fluid flow control method

摘要

downhole fluid flow control system, downhole flow control sieve and downhole fluid flow control method a downhole fluid flow control system (100). flow control system (100) includes a flow control component (122) having direction-dependent flow resistance created by a vortex chamber (144). Production fluids (140) that flow through the flow control component (122) in a first direction enter the vortex chamber (144) and first travel in a tangential direction (148) to undergo a first pressure drop. . Injection fluids (150) that flow through the flow control component (122) in a second direction enter the vortex chamber (144) and first travel in a radial direction (152) to undergo a second pressure drop. . The pressure drop created by the tangential flow (148) of the production fluids (140) is greater than the pressure drop created by the radial flow (152) of the injection fluids (150).
