Title: TAPERED FLUIDIC DIODE FOR USE AS AN AUTONOMOUS INFLOW CONTROL DEVICE (AICD)
Abstract:
A system for providing autonomous flow control of a fluid from a wellbore to an interior of a tubing string by using a variable flow resistance system. The system can include a body, with a chamber that can be configured to induce rotational flow in a fluid that flows through the chamber. The chamber can include an inlet for fluid entering the chamber and an outlet for fluid exiting the chamber. A cross-sectional area of the chamber can be reduced along a central axis of the chamber toward the outlet, with the cross-sectional area being perpendicular to a central axis. A well screen assembly may utilize one or more of the variable flow resistance systems to provide a determined flow resistance and/or flow rate of the fluid through the screen assembly.
