国内轻质油藏注空气、空气泡沫提高采收率效果分析

摘要

在重点调研国内油田空气、空气泡沫驱的基础上,论述了注空气、空气泡沫低温氧化技术的原理,对我国油田开展注空气、空气泡沫驱技术的实际效果以及潜力进行了的分析,认为注空气低温氧化工艺技术安全可控,不但可以解决我国储量丰富的低渗透油藏所面临的开发难题,而且可以进一步提高水驱、聚合物驱后油藏的采收率。随着技术进步,注空气低温氧化技术是我国乃至全世界注气提高采收率技术发展的必然趋势。并通过对现场应用情况分析,给出了对轻质油藏注空气、空气泡沫提高采收率的一些建议。%Based on extensive survey and study on air injection and air foam flooding in oil fields in China,this paper discusses the mechanism of air injection and air foam low temperature oxidation and analyzes the actual effects and potential capacity in China.The result indicates that LTO technology is secure and controllable.LTO can solve the development problem in low permeability reservoir and enhance further the EOR of water drive and polymer drive reservoir.With the technology improvement,air injection LTO technology will be an inevitable trend in EOR of gas injection in the world.By the analysis of field application,some suggestion is put forward to EOR by air injection and air foam flooding in light oil reservoir.
