Abstract:
A downhole fluid flow control system includes a fluid control module having an upstream side, a downstream side and a main fluid pathway in parallel with a secondary fluid pathway each extending between the upstream and downstream sides. A valve element disposed within the main fluid pathway has open and closed positions. A viscosity discriminator including a viscosity sensitive channel forms at least a portion of the secondary fluid pathway. A differential pressure switch operable to open and close the valve element includes a first pressure signal from the upstream side, a second pressure signal from the downstream side and a third pressure signal from the secondary fluid pathway. The magnitude of the third signal is dependent upon the viscosity of the fluid flowing through the secondary fluid pathway such that the viscosity of the fluid operates the differential pressure switch, thereby controlling fluid flow through the main fluid pathway.

Claim (Index 20):
A downhole fluid flow control method comprising:\n positioning a fluid flow control system at a target location downhole, the fluid flow control system including a fluid control module having an upstream side and a downstream side, a viscosity discriminator and a differential pressure switch, the fluid control module including a main fluid pathway in parallel with a secondary fluid pathway each extending between the upstream and downstream sides, the viscosity discriminator having a viscosity sensitive channel that forms at least a portion of the secondary fluid pathway; producing a desired fluid from the upstream side to the downstream side through the fluid control module; operating the differential pressure switch to shift the valve element to the open position responsive to producing the desired fluid by applying a first pressure signal from the upstream side to a first area of the valve element, a second pressure signal from the downstream side to a second area of the valve element and a third pressure signal from the secondary fluid pathway to a third area of the valve element; producing an undesired fluid from the upstream side to the downstream side through the fluid control module; and operating the differential pressure switch to shift the valve element to the closed position responsive to producing the undesired fluid by applying the first pressure signal to the first area of the valve element, the second pressure signal to the second area of the valve element and the third pressure signal to the third area of the valve element; wherein, a magnitude of the third pressure signal is dependent upon the viscosity of a fluid flowing through the secondary fluid pathway such that the viscosity of the fluid operates the differential pressure switch, thereby controlling fluid flow through the main fluid pathway.
