RESILIENT DOWNHOLE FLOW RESTRICTOR

摘要

A flow restrictor includes resilient flaps that can flex outward to an open position in response to fluid flow pressure and return to an initial position at which the resilient flaps restrict fluid flow more than in the open position. The resilient flaps can overlap and variably restrict fluid flow based on fluid flow pressure. The flow restrictor can be used on a transport tube to avoid a need for a packing tube in an alternative path system to deliver gravel packing slurry.
