摘　　要：聚合物驱油技术在国内已经得到了迅速的发展,聚合物驱后如何进一步提高采收率是目前的研究热点。针对河南油田聚合物驱后剩余油分布高度零散的特点并参考室内实验与现场试验成果,提出聚合物驱后进一步提高采收率的方法有微生物驱、三元复合驱、微凝胶驱等,预计聚合物驱后油藏原油采收率可再提高3个百分点,增加139×104t可采储量。Polymer flooding technology has been developing rapidly in China,and how to further enhance recovery fac-tor after polymer flooding has become the focus of research at present.Several measures such as microbial flooding,al-kali-surfactant-polymer flooding and micro gel flooding are presented to further enhance recovery factor according to the c haracteristics of residual oil distribution being highly scattered after polymer flooding and in combination with the laboratory experiment and field pilot res ults.Another3%recovery factor are expected with additional recoverable reserv es of1,390,000t.
