A fluid flow control apparatus ( 100 ) for controlling the inflow of production fluids from a subterranean well includes a fluid discriminator section ( 104 ) and a flow restrictor section ( 106 ) that is configured in series with the fluid discriminator section ( 104 ) such that fluid must pass through the fluid discriminator section ( 104 ) prior to passing through the flow restrictor section ( 106 ). The fluid discriminator section ( 104 ) is operable to autonomously restrict at least a portion of an undesired fluid type, such as water or gas, from the production fluids. The flow restrictor section ( 106 ) is operable to restrict the flow rate of the production fluids, thereby minimizing the pressure drop across the fluid discriminator section ( 104 ).
