鄂尔多斯盆地环县地区延长组长8储层是该地区主要的产油层，也是典型的低孔、低渗透储层。根据岩心观察、铸体薄片及压汞曲线等资料，对环县地区长8储层的岩石学特征、孔喉特征和成岩作用等进行了研究，并对储层进行了综合评价。利用储层物性和孔隙结构参数将长8划分为四类储层，并计算了各类储层的面积，为研究区油气富集规律的深入认识提供了依据。

Chang 8 reservoir of YanChang Formation is the major oil producing zone in Huanxian area, Ordos Basin. It is also typical low porosity and low permeability reservoir. Based on core observation, cast thin section and intrusive mercury curve, the petrology characteristics, pore throat characteristics and diagenesis of Chang 8 reservoir are studied, and the reservoir is also evaluated. According to the physical properties of reservoir and pore structure parameters, Chang 8 sandstone reservoir is classified into four types, and all kind of reservoir area is calculated. It will help to deepen the tmderstanding of the hydrocarbon accumulation regularity of Chang 8 reservoir.
