Abstract
An apparatus and method are described for autonomously controlling flow of fluid in a subterranean well, where fluid flow is controlled based on a fluid characteristic, such as viscosity or density, which changes over time. Fluid flows into a vortex assembly where a centrifugal force is imparted to the fluid. A less viscous fluid will have a relatively greater velocity and centrifugal force than a more viscous fluid. The fluid exits the vortex chamber (32) by both a vortex outlet (40) and a peripheral outlet (42). An autonomous valve element (52) moves between an open position (56), in which fluid flows freely through the peripheral outlet (42), and a closed position (58), in which fluid flow through the peripheral outlet (42) is restricted. The valve element (52) is moved by the centrifugal force of the fluid, such that a fluid having a higher centrifugal force moves the valve element (52) to the closed position (58), thereby reducing the total fluid flow through the vortex assembly. The most suitable drawing: FIG. 1
