Abstract:

Based on the study of petrology,using the data of cathodoluminescents,stable iso-topes of oxygen and carbon,trace elements and composite colouring,the diagenesis,diage-netic sequences and pore evolution of Upper Carboniferous carbonates in Central Hubei were studied in detail.The study shows that filling,cementation,solution,dolomitization,compaction and pressure-solution were the principal factors in controlling the reservoir properties of the Upper Carboniferous in Central Hubei,the most important of which were the dolomitization,solution in deep burial environment and pressure-solution in forming the pores of accumulation stage.
