摘要(Abstract)：

针对陕北裂缝性低渗透油藏物性差、非均质性严重及传统调剖效果差问题,研究自适应弱凝胶辅助氮气泡沫复合调驱技术中弱凝胶和氮气泡沫的配伍性,优化复合调驱体系的注入参数,评价复合调驱体系的驱油性能.结果表明:复合体系具较好复配性,室内优化凝胶段塞大小最优注入体积为0.3PV,泡沫最优注入体积为0.6PV,在设备允许的条件下尽量用小段塞、多轮次注入泡沫液;水驱高含水率后,优先注入凝胶段塞,再注入泡沫,调堵效果最好,复合调驱体系双管岩心驱替相对提高采收率幅度达43.69%;矿场试验井组含水率由80%下降至62%,单井日产油量由0.27m3增至0.70m3.复合调驱技术在GY油田具有较强适应性,大幅度提高油田采收率,可为同类油藏增油控水提供借鉴.
