【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 solve the problem that it is difficult to classify strongly heterogeneous reservoirs in East African Rift Valley H oilfield and realize three-dimensional quantitative characterization, based on 36.5 m core and 399 samples, the core description, physical property analysis and thin slice analysis are adopted. The reservoir was classified by scanning electron microscope and capillary pressure analysis. The results show that the reservoir can be classified into 4 types by synthesizing lithology, physical properties, pore structure characteristics and percolation ability, and on the basis of reservoir classification, the electrical parameters of reservoir, that is, muddy content and density, can be screened by establishing the relationship between rock and electricity. The reservoir classification on single well is completed according to electrical parameters and limit values, and the fine reservoir geological model is constructed by using two key parameters and limit values of flow zone index and throat radius. Finally, the reservoir three-dimensional quantitative representation is realized, which lays a foundation for the development plan.
