The study for geological storage of CO2 has been more than ten years in China,but the optimization system of CO2 geological storage target area is not established yet.This embarrass situation has been restricting the development of the applications of geological storage of CO2.Based on the references of CO2 geological storage and the previous research results,we analyze the effect of the geological background,basinal resource and reservoir characteristics upon the CO2geological storage,and establish the evaluation system for the CO2 geological storage.By AHP to determine weights,we make the indicator standardization using dimensionless index approach,and evaluate the target areas using the weighted average model.Finally,we evaluate and sort some CO2 geological storage areas in China.The application results show optimization system can effectively guide the use of CO2geological storage to improve the efficiency of reservoir exploitation.
Key words： CO2; Geological storage; Target area; Effect factor; Weight; Comprehensive evaluation.
