摘要

CO_2 displacement and storage technology is a feasible technology for developing countries to relieve energy supply and control climate change. Based on the fractional flow theory, considering comprehensive key factors affect CO_2 flow in reservoir, including viscous fingering, gravity separation, and reservoir heterogeneity, to establish CO_2 miscible displacement mathematical model and develop evaluation software CS-EOR. Aiming at the concrete reservoir, the oil displacement and CO_2 storage efficiency assessment were carried out, and the CO_2 utilization coefficients were quantified. The results will provide important theoretical foundation and reliable tool for further the evaluation of CO_2 injection project in mature oil reservoir around the word.
