摘　　要：鄂尔多斯盆地富县探区长2-长8储层砂岩类型主要为长石砂岩和岩屑质长石砂岩,搬运方向主要为北东-西南、北-南走向,轻质岩石矿物没有明显的变化,继承性较好。研究区石英含量较高的层位区域是长8油层组南部,该区砂岩粒度分析主要为细砂岩-粉砂岩,其分布规律不强,延长组砂岩物性为低孔-特低渗储层。The sandstone types of Chang 8-chang 2 reservoir in Fuxian exploration area of Ordos Basin are mainly arkose and lithic arkose.The transportation direction is mainly ne,and the change of light minerals is not obvious,which has a certain inheritance,mainly NE and ne.The quartz content of sandstone in the south of Chang 8 reservoir in the block is relatively higher.The grain size of sandstone is mainly fine sandstone siltstone,and its distribution law is not strong.The physical property of sandstone in Yanchang formation is low porosity and ultra-low permeability reservoir.
