SYSTEM AND METHOD FOR CONTROLLING FLUID FLOW IN A DOWNHOLE COMPLETION

摘要

A technique facilitates control over production flow from a well in a manner which increases the longevity of the well. A sand screen assembly or a plurality of sand screen assemblies may be constructed for use in a production operation. Each sand screen assembly comprises a base pipe, a screen, an inflow control device, and a plurality of plugs located between the base pipe and the screen. The plurality of plugs is held initially by corresponding release mechanisms at a position upstream of a bypass. The bypass comprises a plurality of flow passages which route inflowing fluid through the inflow control device and into an interior of the base pipe. The plugs are sized to at least partially plug corresponding flow passages of the bypass upon the occurrence of a trigger event which causes a release mechanism or release mechanisms to release corresponding plugs.

1. A system for use in a well, comprising:
a sand control system having a plurality of sand control assemblies separated by a plurality of packers, each sand control assembly comprising:
a base pipe;a screen positioned along an exterior of the base pipe;an inflow control device;a bypass ring having flow passages positioned such that fluid flowing inwardly through the screen passes through the flow passages before entering an interior of the base pipe via the inflow control device;a plurality of plugs disposed between the base pipe and the screen, the plugs each being sized to plug a corresponding flow passage of the flow passages; anda plurality of release mechanisms which individually hold the plurality of plugs away from the flow passages until a triggering event.
