To predict distribution of diagenetic stages of Xihu Sag Huagang Formation sandstone reservoir and secondary pore development zone, and research original pore reservation and secondary pore increase and decrease in reservoir evolution process, combining traditional diagenesis research and numerical simulation technique, and based on interaction model and effect model, this paper establishes a aggregative model on numerical simulation of diagenetic stages. In diagenesis simulation process, based on process response principle, and restricted by current diagenetic stage distribution and type, diagenetic stage distribution and type of reservoir during geological historical evolution period is back stripped through diagenetic temperature. Taking single well diagenetic stage data as constraint condition, and combining with research area burial history, ground temperature history, and diagenetic stage division basis, and scheme, plane distribution of diagenetic stages of the whole research area during each geological historical period is finally obtained.
