湖南石门地区中上寒武统为一套浅海碳酸盐岩沉积，以局限台地潮坪沉积力主，其次为浅滩沉积。在薄片观察的基础上，使用阴极发光显微镜、电子探针、Ｘ衍射分析、和碳／氧同位素分析资料，研究了该区碳酸盐岩的主要成岩作用类型，如胶结作用、白云石化作用、溶解作用等。恢复和建立了该区碳酸盐岩的成岩环境和孔隙演化历史，对该区的储层特征进行评价，认为最好的储层为结晶白云岩型储集层。
The middle-upper Cambrian of Shimen area in Hunan Province is a set of shallow-sea carbonate sediments, mainly dominated by tidal flat sediments, followed by shallow shoals. Based on the observation of thin slices, the main diagenetic types of carbonate rocks in this area were studied by using cathodoluminescence microscope, electron probe, X-ray diffraction analysis and carbon / oxygen isotope analysis data, such as cementation, dolomitization, Dissolution and so on. The diagenetic environment and pore evolution history of carbonate rocks in this area have been restored and established. The reservoir characteristics of this area have been evaluated. The best reservoirs are crystalline dolomite reservoirs.
