鄂北上古生界砂岩储层岩性复杂,为中孔低渗储层。综合岩石学特征、物性分析、沉积相、成岩作用等资料分析,认为沉积微相的分布基本上决定了有利储层的发育,明确了有利储层发育的沉积微相,研究了成岩相对储层储集性能的影响,总结出了影响储层物性的主要因素,为研究区下一步勘探开发提供了科学的地质依据。 Upper Paleozoic sandstone reservoirs in northern Hubei have complex lithology and are medium-porosity and low-permeability reservoirs. Based on the analysis of petrology, petrophysical properties, sedimentary facies and diagenesis, it is considered that the distribution of sedimentary microfacies basically determines the development of favorable reservoirs, clarifies the sedimentary microfacies of favorable reservoirs and studies the distribution of diagenetic relative reservoirs The main factors affecting reservoir physical properties are summed up, which provides a scientific geological basis for the next exploration and development in the study area.
