Abstract:
Water injection flow control device, distinctive in that it comprises: a stack of discs or cone-like plates, the discs or cone-like plates as stacked or per se comprises in substance spiral shaped flow conduits, the spiral shaped flow conduits comprises at least one revolution, the spiral shaped flow conduit being turned about a central point or axis and departing or approaching said central point or axis for each revolution, at least some of said spiral shaped flow conduits comprises at least one of sections in series with alternating cross section area for flow and a section with serpentine-type shape for flow along the in substance spiral shaped flow conduits, said spiral shaped flow conduits has a fluid conduit length of at least 0.2 meter, an inlet operatively coupled to an inner or outer end of the spiral shaped flow conduits, an out-let operatively coupled to the other end of said conduits than the inlet, and a control member. The invention also provides a system comprising said device and use of said device.

Claim (Index 3):
The water injection flow control device according to  claim 1 , wherein at least some of the in substance spiral shaped flow conduits comprise a section with serpentine-type shape for flow in the spiral shaped flow conduits, with sections of constant or variable cross section area in serpentine shape along a central flowline of in substance spiral shape, the shape of the serpentine can be as square waves or sinusoidal waves or combinations between, preferably each of a wave periodicity P, the distance between repeated waves, and a wave amplitude A, the distance between top and bottom of the repeated waves, are between 4 and 40 d, wherein P and A are equal or different in any combination, and wherein d is a dimension in the flow conduit transverse to a central flow line along the serpentine-type flow or d is the smallest or a typical conduit cross section diameter.
