摘　　要：长水平井生产剖面难以均衡推进,易过早见水。传统流入控制装置(ICD)存在见水后失效的问题。本文提出一种新型自适应流入控制装置(AICD),该装置基于多级限流原理,结合遇水膨胀材料,根据含水率自动改变流动阻力等级,以达到控水稳油的目的。设计了全尺寸物理模拟试验装置,与国际上主要应用的AICD进行了对比试验。结果表明,该装置结构简单,防堵能力强,具有卓越的性能,对流体黏度、密度不敏感,在中高含水情况下,控水稳油效果显著。The production profile of the long horizontal wells is difficult to promote evenly which occurs water breakthrough easily.Traditional ICD structures will be disabled when water break through occurs.Combining continuous jet principle and WSR,an autonomous inflow control device design was proposed which can adjust its water resist level responding to water cut change,thus achieving the purpose of stabilizing oil production and water control.Comparing the mainly applied AICDs by the full-scale experiment,experimental results show that the device is insensitive to viscosity or density and have simple structure.The device has excellent performance in stabilizing oil production and water control in medium or high water cut stage.
