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 by both a vortex outlet and a peripheral outlet. An autonomous valve element moves between an open position, in which fluid flows freely through the peripheral outlet, and a closed position, in which fluid flow through the peripheral outlet is restricted. The valve element is moved by the centrifugal force of the fluid, such that a fluid having a higher centrifugal force moves the valve element to the closed position, thereby reducing the total fluid flow through the vortex assembly.

Description

technical field [0001] The present invention generally relates to methods and apparatus for selectively controlling the flow of fluids from a formation in a hydrocarbon containing formation into a production casing in a wellbore. More specifically, the present invention relates to a method for controlling the flow of a fluid according to a certain characteristic such as viscosity or density, by utilizing the Actuated) swirl chamber, method and apparatus for controlling fluid flow. Background technique [0002] During completion operations on a well passing through a hydrocarbon-bearing formation, production tubing and various equipment are installed in the well to enable safe and efficient production of fluids. For example, to prevent the production of particulate material from unconsolidated or loosely consolidated formations, some completions include one or more sand control screens located near the desired production zone. In other completions, to control the flow of pr...
