摘要： 为解决东非裂谷H 油田强非均质储层难以精细分类及难以实现三维定量表征的问题，基于36.5 m岩心和399 样次分析化验资料，通过岩心描述、物性分析、薄片分析、扫描电镜以及毛管压力分析等，对储层进行了精细分类。结果表明：综合岩性、物性、孔隙结构特征和渗流能力等，将储层精细划分为4 类；在储层分类的基础上，通过建立岩-电关系，筛选出储层电性参数，即泥质含量和密度，并依据电性参数及界限值完成了单井上的储层分类；利用流动带指数和喉道半径这2 个关键参数及界限值，构建了精细储层地质模型。最终实现了储层三维定量表征，为编制开发方案奠定了基础。

Abstract: In order to carry out the fine classification and 3D quantitative characterization of strong heterogeneity reservoir in H oilfield which lies in Albert Basin,the East African Rift,the heterogeneity reservoir classification was studied based on 36.5 m cores and assay data of 399 samples,by analyzing physical properties,thin section, scanning electron microscope and capillary pressure. The result shows that reservoirs were divided into four types according to lithology,properties,pore structure and seepage capacity. The key parameters of shale content and density were selected from logging data based on the reservoir classification result and the relationship of lithology- electrical log. The reservoir rock types were classified on the wells with the parameters. Then the reservoir geologic model was established by the parameters of flow zone indicator and pore throat radius. And finally the quantitative reservoir characterization was carried out,which lays the foundation for development programs.

Key words: coalbed methane, development geological unit, coal body structure, desorption pressure, ground stress, Zhengzhuang block, qinshui Basin
