Abstract
A water injection flow control device includes a stack of discs or cone-like plates that form spiral-shaped flow conduits. The spiral-shaped flow conduits form at least one revolution about a central point or axis and depart or approach the central point or axis for each revolution. At least some of the spiral-shaped flow conduits have sections in series with alternating cross sectional area for flow and at least some have sections with a serpentine-type shape for flow along the spiral-shaped flow conduits. The spiral-shaped flow conduits have an inlet coupled to an inner or outer end of the spiral shaped flow conduits, an outlet coupled to the other end of the spiral-shaped conduits, and a control member.
