摘要
为探索进一步提高低渗透油藏采收率的方法,调研分析了国外多个低渗透油田注空气-空气泡沫的现场应用情况.提出了国内急需在低渗透油藏注空气-空气泡沫方面开展研究,形成注空气-空气泡沫提高采收率的配套技术。
In order to explore for methods of further enhanced oil recovery of low permeability reservoirs, field application of air-in- jection and air-foam-flooding to a number of foreign low permeability oilfields is investigated and analyzed. The authors put forward that our country is badly in need of carrying out researches on air-injection & air-foam-flooding in low permeability oil reservoirs, forming supporting technology of air injection - air-foam flooding to enhancing oil recovery.
