| Abstract: | 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. |
