低渗透油藏大多属于轻质油藏,轻质油藏注空气已经越来越受到人们的关注。通过调研国内外大量的文献,论述了轻油注空气技术的机理,分析了轻油注空气与重油层内燃烧的区别,阐述了高压注空气室内评价实验。通过实例分析了轻油注空气技术的经济性,并对我国发展轻油高压注空气技术的前景进行了分析。最后指出轻油注空气特别适用于注水开发效果差的低渗及特低渗等采用常规开采方法开发效果差的油藏。 Most of the low-permeability reservoirs belong to light oil reservoirs, and light-oil reservoirs have attracted more and more attention. Through investigating a large number of literatures at home and abroad, the paper discusses the mechanism of light oil injection air technology, analyzes the difference between light oil injection and heavy oil combustion, and expounds the indoor evaluation experiment of high pressure injection air. The economy of light oil injection air technology is analyzed through an example, and the prospect of developing high pressure injection of light oil gas technology in China is analyzed. Finally, it is pointed out that the light oil injection air is especially suitable for reservoirs with poor performance in low permeability and ultra low permeability, etc., which are developed by conventional mining methods.
