摘要
介绍了气驱提高采收率的机理,并分析其影响因素,综述了CO_2驱、氮气驱、天然气驱和空气驱的研究应用进展。气驱具有高效驱油、成本低廉的独特优势,不但能够解决低渗透油藏开发面临的难题,而且进一步提高水驱、聚合物驱后油藏的采收率。同时,气驱技术存在一些不容忽视的局限性和不利因素,所以要加强注气驱提高采收率的理论和实验研究,为进一步提高原油采收率打下基础。
The mechanism of Gas flooding was described,and its influencing factors were analyzed,some advances in research and application were summarized,including CO2 flooding,nitrogen flooding,natural gas flooding and air flooding. Gas flooding has some advantages,including high efficient and low cost. It can not only solve the develop problem of low permeability,but also further improve the recovery after water flooding or polymer flooding. At the same time,there are some undeniable limitations and disadvantages,so the theoretical and experimental must be strengthened to lay foundation for further enhance oil recovery.
