摘　　要：二氧化碳驱油封存技术因其经济优势而成为节能减排的重要手段。文章基于二氧化碳埋存的工程模型和经济模型,分析讨论了有关影响因素。研究表明,二氧化碳在临界条件下溶解度最小,从而影响总埋存量;溶解埋存量占总埋存量的比例较小,可用空间埋存量来表示总埋存能力;温度是影响埋存量的主要因素。二氧化碳深井埋存所需成本会增大,平均增长率为1.608%每百米;埋存量越大成本越高,在二氧化碳临界条件下总成本最低。Carbon dioxide （C02） sequestration in oil reservoir is one of the major mitigation strategy for reducing the intensity and amount of C02 in the atmosphere due to its economic advantage. Based on the engineering-economic model of C02 sequestration, this paper analyzes and discusses the relevant influence factors. The research results show that the solubility of CO2 is minimum in critical condition so as to affect total sequestration amount; the sequestration due to solution is a small portion of the total sequestration amount so the total sequestration amount can be represented by the spatial sequestration amount; temperature is main factor affecting sequestration amount. C02 sequestration by deep well will increase cost which increases 1.608% per 100 meters of well depth in average; the cost increases with increasing sequestration amount and the total cost reaches maximum in C02 critical condition.
