摘　　要：三次采油技术要求针对不同的地层条件,开展不同的聚合物适应性评价,选择合适的聚合物才能使得驱替地层原油效果更佳。同时目前一般的聚合物已经无法满足三次采油的技术需要,优选新型聚合物开展三次采油可行性室内实验论证,成为了目前必要的研究过程。因此,针对大港油田采油五厂,优选了3种聚合物进行室内岩心驱油实验分析,研究表明,3种新型聚合物都能有效的起到提高采收率的效果,平均提高采收率达21%。实验分析结果为聚合物驱油现场实施提供理论指导。The tertiary oil recovery technology requires different polymer adaptability evaluation for different formation conditions,and the selection of suitable polymers can make the oil displacement better.At the same time,the general polymer has been unable to meet the technical needs of the tertiary oil recovery.It is a necessary research process to optimize the feasibility of a new type of polymer to carry out the feasibility laboratory demonstration of the tertiary oil recovery feasibility.Therefore,for the five oil production plant in Dagang Oilfield,3 kinds of polymer were selected to carry out the laboratory analysis of the laboratory core flooding,and the study shows that the 3 kinds of new polymers can effectively improve the recovery efficiency,and the average recovery rate is up to 21%.The experimental results provide theoretical guidance for on-site implementation of polymer flooding.
