摘　　要：注空气采油技术作为一种经济有效的提高原油采收率的方法,受到国内外的广泛关注。原油注空气氧化反应及其动力学研究,一方面可作为该技术在油田应用上的可行性评价,另一方面也是加快耗氧速率和保证生产全过程安全性的关键。本文综述了国内外原油注空气氧化反应模型和动力学的研究进展,指出了各类氧化反应模型的优缺点,认为等转化率法今后将成为原油氧化动力学研究的得力工具,提出了今后应该重点研究建立适合具体油藏的氧化反应模型,以及总压力或者氧分压对原油氧化反应速率的影响,以确定氧气的反应级数。As a cost-effective method of enhanced oil recovery,air injection enhanced oil recovery technology has gained widespread attentions from all over the world. Studies on the oxidation reaction of air injection and its kinetics can be used for feasibility evaluations of its applications in oilfield and accelerating the rate of oxygen consumption and therefore ensuring the security of production process. The research progress of oxidation reaction model and kinetics of air injection in crude oil is reviewed in this paper. Both the advantages and disadvantages of these oxidation reaction models were discussed,and it was concluded that the isoconversional method would be a powerful tool in the future for crude oil oxidation kinetics studies. Besides,suitable oxidation reaction model for specific reservoir,effects of total pressure or oxygen partial pressure on the oxidation rate of crude oil,and oxygen reaction order should be further studied.
