Abstract (en)

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).
