摘　　要：储层岩石中粘土矿物种类及含量分析是划分沉积相带和成岩相带的基础，也是油气层钻井、完井、开发改造中储层保护的关键。本文在分析传统粘土矿物抽提分离方法及其缺点的基础上，提出了多级粒度抽提分离方法，为分析储层岩石中的粘土矿物种类和含量提供了首要的保障。Quantitative analysis of minerals in reservoir rocks is the basis to determine sedimentary and diagenetic factes, and is one of the key factors to reservoir protection during the process of drilling, well-completion and oil production. On the basis of investigating the traditional segregation of clay minerals and its defects; a multiple grain size segregation method was put forward, which ensured the qualitative and qantitative determination of clay minerals in reservoir rocks.
