摘　　要：利用物理模拟、数值模拟、测井解释、检查井取心分析等方法,对多层非均质砂岩油田聚合物驱后剩余油宏观和微观分布规律进行了研究。分析认为,中等渗透率厚油层是聚合物驱后剩余油主要潜力所在。针对不同类型剩余油,提出了继续挖潜的对策和措施。By physical modeling, numerical modeling, well-logging interpretation, analysis of cores taken from inspection wells, and other methods, macroscopic and microscopic distribution of the remaining oil after polymer flooding was investigated for heterogeneous multi-layer sand oil field. This study shows that the main remaining potential after polymer flooding lies in thick layers with intermediate permeability. In addition, suitable strategies and measures were proposed for producing different type of remaining oil.
