摘要
应用碱／聚合物复合体系驱油是一种三次采油方法，对提高原油采收率有较大的意义。本文介绍了在大港羊三木油田馆Ⅱ上油组油藏地质条件下进行的碱／聚合物复合体系驱油的室内实验研究成果，优选出适合该油藏的碱／聚合物复合体系的最佳配方和注入方式，提出了矿场试验方案设计参数。
lkali/polymer combinational flooding is a tertiary oil recovery method which is of greatsignificance to raising oil recovery ratio. This paper presents the laboratory research resultsof akali/polymer combinational flooding in the upper reservoir of the 2nd member of Guan-tao formation in Yangsanmu oil field,Dagang area. It also describes the optimal chemicalprescription and injection pattern of alkali/polymer combinational flooding system which issuitable to this reservoir. It also details field experiment plan and the design parameters.
