Downhole Fluid Flow Control System and Method Having a Fluidic Module with a Flow Control Turbine
First Claim
1. A downhole fluid flow control system comprising:
- a fluidic module having a turbine chamber; and
a flow control turbine rotatably disposed within the turbine chamber, the flow control turbine operable to provide fluid discriminating flow resistance such that a pressure drop for a desired production fluid passing through the fluidic module is less than a pressure drop for an undesired production fluid passing through the fluidic module.

Abstract
A downhole fluid flow control system includes a fluidic module having a turbine chamber. A flow control turbine is rotatably disposed within the turbine chamber. The flow control turbine is operable to provide fluid discriminating flow resistance such that a pressure drop for a desired production fluid passing through the fluidic module is less than a pressure drop for an undesired production fluid passing through the fluidic module. For example, the flow control turbine is operable generate a greater pressure drop in water produced therethrough as compared to oil produced therethrough due to differences in the density, viscosity or other property of the produced fluid.

11. A flow control screen comprising:
-
a base pipe with an internal passageway; a filter medium positioned around the base pipe; a housing positioned around the base pipe defining a fluid flow path between the filter medium and the internal passageway; and at least one fluidic module disposed within the fluid flow path, the fluidic module having a turbine chamber with a flow control turbine rotatably disposed therein, the flow control turbine operable to provide fluid discriminating flow resistance such that a pressure drop for a desired production fluid passing through the fluidic module is less than a pressure drop for an undesired production fluid passing through the fluidic module. - View Dependent Claims (12, 13, 14, 15, 16)

17. A downhole fluid flow control method comprising:
-
positioning a fluid flow control system at a target location downhole, the fluid flow control system including a fluidic module having a turbine chamber with a flow control turbine rotatably disposed therein; producing a desired fluid through the fluidic module; generating a first pressure drop responsive to production of the desired fluid; producing an undesired fluid through the fluidic module; and generating a second pressure drop responsive to production of the undesired fluid, the second pressure drop being higher than the first pressure drop, thereby providing fluid discriminating flow resistance. - View Dependent Claims (18, 19, 20)
