摘　　要：对大庆萨尔图油田北一区断东葡一组储层进行精细刻画,通过沉积微相、单砂体、点坝内部构型3个层次的研究,逐层深入进行了储层层次分析,总结出一套有效实用的曲流河精细地质研究方法与流程,重新构建地下认识体系。在此基础上建立地质模型,开展聚合物驱后剩余油研究,聚合物驱后剩余油主要分布在河道砂体顶部、注采不完善及分流线部位,分布类型主要以韵律性及夹层控制型和薄差油层型为主。With fine reservoir description of Pu I Formation of Beiyiquduandong in the Saertu Oilfield,this paper,through three-level research on the sedimentary microfacies,single sand body,and the internal point bar-level configuration,performs an in-depth analysis of the reservoir layer by layer,summarizes a set of effective and practical meandering river fine geologic research methods and processes,and rebuilds the reservoir cognition system.On this basis,this paper establishes a geological model,and conducts remaining oil research after polymer flooding.It is found that after flooding,remaining oil is mainly distributed at top of channel sand body,the imperfect injection-production part and the branching line;the distribution is dominated by rhythmic type,interbed-controlled type and the thin and poor reservoir type.
