摘要
作者以扫描电镜为手段,从微观上分析了湖北长阳地区中上寒武统碳酸盐岩的岩石矿物组成、结构构造特征、主要孔隙结构类型及储集空间特征。通过对长阳地区中上寒武统碳酸盐岩的成岩作用类型进行研究,分析了不同成岩作用及相关的成岩环境对碳酸盐岩孔隙发育的影响,并根据碳酸盐岩储层的微观成岩组构、成分和成岩现象探讨了不同成岩阶段与储集性的关系及其受控因素,为碳酸盐岩储层评价提供了微观分析手段。
By means of SEM, the composition of rock mineral, the features of rock textures, the types of main pore structures and the characteristics of reservoir spaces in the Middle-Upper Cambrian carbonate rocks of Changyang area, Hubei province were analysed microscopically. Based on the study of diagenetic types in the Middle-Upper Cambrian carbonate rocks of Changyang area, the effects of various diageneses and related diagenetic environments on the pore development of carbonate rocks were analysed. According to the microscopic diagenetic fabric, components and diagenetic phenomena of carbonate rock reservoirs, he controlling factors of reservoir performance and its relations to various diagenetic stages were discussed. This provided microscopic analytical means for the evaluation of carbonate rock reservoirs.
