摘要
介绍了国外提高油气采收率（ＥＯＲ）方法的应用现状、应用规模、增油量及其在总产量中的比例；介绍了美国能源部支持的三次采油基础研究情况；分析了ＥＯＲ方法与油价的关系；分析了我国在聚合物驱、复合驱、注气、微生物采油等方面的技术状况和应用规模，对近期的发展思路提出了建议。
This paper presents foreign EOR methods and their application status, application scale, incremental oil production and its share in total oil production. The basic research of tertiary oil recovery supported by U.S. Ministry of Energy is presented too. The relations between EOR methods and oil price have been analyzed. The technique situation and application scale in China of polymer flooding, combination flooding, gas injection and microbial oil recovery, etc., have been analyzed too. Suggestions about near future developing thinking have been made.
