摘　　要：辽河油田曙三区处于复杂断块地区,由于区块内断层发育,使得流动单元平面分布复杂。选取多种参数运用因子分析法进行曙三区流动单元划分,通过这种方法提取公共因子作为主要参数,以因子得分为分类依据,将该区取心井与非取心井的流动单元划分为4类,通过微观非均质性和岩心分析特征对其分类进行验证。并且对影响渗流屏障分布的各个影响因素(沉积因素,成岩因素,构造因素和生产动态因素)进行分析和探讨。对流动单元空间分布的研究,能够揭示流动单元与平面剩余油形成分布关系,揭示研究区剩余油富集区,指导油田开发,改善开发效果。Shu 3 Area was consisted of several intricate faults which made the plane distribution for flow units more complicated in this area.Factors analyzing with multi-parameters was applied in plotting flow units in the studied area.With this method,some common factors were chosen as primary parameters.The flow units were classified from coring wells and non-coring wells were classified into four groups.And testified them with characteristics of micro-heterogeneity and researches on core wells.Then all kinds of the flow barrier characterizations were analyzed (sedimentary factor,diagenism factor,structure factor and producing factor) which affected the distribution of flow units.Finally,the special distributions of flow units are well constrained.Studies on flow units can offer a linkage with the distribution of remaining oil,and uncover the areas enriched in remaining oil.Under the guidance of these studies,the development of oil fields can be improved.
