本文全面回顾了国内外关于提高石油采收率研究概况及我国油田开采的实际情况,阐明了开展大幅度提高石油采收率基础研究的意义。通过三年研究在廉价、高效、无污染驱油表面活性剂分子设计,新型耐温抗盐聚合物分子设计,数字化油藏研究,油藏物理模拟研究和油藏数值模拟软件等方面取得了重要阶段成果。在基础理论研究取得重要进展的同时,为了进一步检验本项目研究成果,将研究成果转变为生产力,在胜利油田胜陀一区南部正在开展耐温抗盐聚合物驱油矿场试验,在大港油田港西三区三断块开展三元复合驱矿场试验,初步显示出了良好的应用效果。
This paper reviews the general situation of research on oil recovery at home and abroad and the actual situation of oil field exploitation in China and abroad and expounds the significance of carrying out the basic research on greatly increasing the oil recovery rate. After three years of research, it has made important achievements in molecular design of cheap, efficient and non-polluted surfactant, new molecular design of temperature and salt resistance polymer, digital reservoir research, reservoir physical simulation and reservoir numerical simulation software Stage results. While making important progress in basic theory research, in order to further test the research results of this project and turn the research results into productive forces, a temperature-resistant and salt-resistant polymer flooding oil field test is being conducted in the southern part of Shengdou No. 1 District of Shengli Oilfield. In Dagang Oilfield Port Three blocks in the west three areas to carry out the ASP flooding field test initially showed a good application effect.
