摘　　要：本文主要介绍了利用高压注空气技术提高低渗透轻质油油藏采收率的原理,及其与稠油火烧油层工艺的主要区别,综合国外现场及实验室的研究资料,指出:油藏在空气过程中自燃、烟道气与轻质油油藏条件下发生混相,是低渗透轻质油油藏注空气成功开发的2个主要条件,并列举了国外注空气开发低渗透轻质油油藏的几个成功实例。This paper introduces the theory of improving recovery factor of low permeability light oil reservoir by high pressure air injection and its major differences with in situ combustion. Combining with foreign research data, it is point out that the two important conditions for successful development of such reservoirs by air injection are self- combustion in reservoir during injection and forming of mixed phase of flue gas and light oil under reservoir conditions. Successful foreign examples are also provided.
