摘　　要：以精细的小层对比为基础,通过对岩心相、地质录井相、测井相的研究,明确了河西务油田Axx断块主要为辫状河三角洲沉积,沉积微相主要为辫状河道、分流水道、席状砂;通过储层非均质性、沉积微相的分布、油层分布的研究,表明沉积相带的展布决定了平面的非均质性以及高渗条带的分布,油层分布特征表明油层的分布受构造、砂体的双重控制。沉积微相的研究指导了本断块的开发。On basis of minelayer correlation,by comprehensively study of core facies,and geological logging facies and well log facies,this paper discusses that Axx fault block is mainly braided river delta sediment,sedimentary microfacies aremainly braided channel,distributary channel and sand sheet. The research of reservoir heterogeneity,sedimentary microfacies distribution,and oil layers distribution has shown that plane nonhomogeneity and high vadose zone developed by distribution of sedimentary facies as well as oil layers distri-bution is dual controlled by tectonics and sand body. The research on sedimentary microfacies guided the development of the study block.
