摘要(Abstract)：

被动式流入控制装置(PICD)在油井见水后易失效.提出一种基于混合型流入控制装置(ICD)和遇水膨胀橡胶(WSR)的自膨胀型自适应流入控制装置(AICD),分析流体性质敏感性并优化结构参数,与喷嘴型、喷管型、螺旋通道型和混合型等4种流入装置(在流动阻力等级FRR相同时)比较.结果表明:一旦油井见水,自膨胀型AICD上预装的遇水膨胀橡胶膨胀,且膨胀度根据含水率自动变化,从而改变装置的最小过流面积和流动阻力等级;在泥浆返排阶段防堵塞能力强,在稳产期抗冲蚀性能强,在衰竭生产时能够持续控制入流且对黏度不敏感.该装置还可以根据流体类型自动改变流动阻力.

关键词(KeyWords)：自膨胀型;混合型;自适应流入控制装置(AICD);遇水膨胀橡胶(WSR);数值模拟
