发明名称 FLOW RESTRICTION DEVICE
摘要 An inflow control device may include flow control elements along a flow path. The flow control elements may change the inertial direction of the fluid flowing in the flow path. The change in inertial direction occurs at junctures along the flow path. The flow control elements may also be configured to form segmented pressure drops across the flow path. The segmented pressure drops may include a first pressure drop segment and a second pressure drop segment that is different from the first pressure drop segment. The pressure drop segments may be generated by a passage, an orifice or a slot. In embodiments, the plurality of flow control elements may separate the fluid into at least two flow paths. The flow control elements may also be configured to cause an increase in a pressure drop in the flow path as a concentration of water increases in the fluid.
