Autonomous inflow control device having a surface coating

摘要

An autonomous inflow control system for use downhole comprises a flow ratio control system comprising one or more fluid inlets, and a pathway dependent resistance system comprising a vortex chamber. The one or more fluid inlets provide fluid communication between the flow ratio control system and the pathway dependent resistance system, and at least one of the one or more fluid inlets comprises a super hydrophobic surface.

1. An autonomous flow control system for use downhole comprising:
a vortex chamber comprising a super hydrophobic surface; a first leading passageway that directs fluid into the vortex chamber via a first inlet and a second inlet; and a second leading passageway that directs fluid into the vortex chamber via a third inlet and a fourth inlet, wherein the first leading passageway and the second leading passageway are separated by the vortex chamber.
