摘　　要：以大庆油田杏十三区太103井区为例,通过岩心及测井资料分析,得出研究区PI油层组在河流-三角洲沉积背景下主要发育分流河道、废弃河道、决口水道、溢岸薄层砂和分流河道间等微相.通过沉积时间单元精细划分、对比、测井微相模式的建立以及沉积微相研究,揭示了单砂体的空间分布规律,为高含水油田剩余油预测、开发调整提供了可靠的地质依据.The remaining oil distribution in high water-cut oilfields is very dispersed,and therefore it is more difficult and more difficult to tap the potential remaining oil of the oilfields.Therefore,it is possible to carry out the fine study of the sedimentary microfacies of single sand-body in high water-cut oilfield.According to the analyses of cores and logging data of PI oil-bearing formation of Tai-103 wellblock,it is held that in the oil-bearing formation is developed distributary channel microfacies,abandoned channel microfacies,crevasse channel microfacies,sheet sand microfacies,distributary interchannel microfacies in the sedimentary setting of river-delta.The special distribution law of the sandbodies is understood according to the division and correlation of depositional time unit,the establishment of logging sedimentary microfacies model and the study of sedimentary microfacies,which supplies important geological basis for the prediction of the remaining oil and the adjustment of the development plan of the oilfield.
