摘　　要：文明寨油田位于东濮凹陷中央隆起带北端,是一个受断块控制的复杂油气藏。储层砂体主要为古近系沙河街组,剩余油丰富。对该区块的研究主要集中在剩余油的开发,对沉积相与剩余油分布关系的研究较少。以岩心、测井及录井资料为依据,对文明寨油田的沉积相进行了研究,研究区主要发育水下分流河道、水下分流间湾、河道漫溢、席状砂、河口坝及前三角洲泥等微相类型。运用监测资料分析了沉积微相与剩余油分布的关系,并对不同微相砂体剩余油的开发提出了针对性的建议。Wenmingzai Oilfield which was located in the north of central uplift belt of Dongpu Depression,was a complex oil and gas reservoir controlled by fault blocks.The main reservoir sand was Paleogene Shahejie Formation,where remaining oil was abundant.Previous studies of this area mainly aimed at the development of remaining oil,studies on the relationship between sedimentary facis and the distribution of remaining oil were few.Based on rock core,logging and mud logging data,the sedimentary facis of Wenmingzai Oilfield was studied,it was indicated that there existed developed subsea distributary channel,subsea interdistributary bay,river overflow deposits,sheet sand,river mouth bar and frontal delta mud and so on in the area.The monitoring data are used to analyze the relationship between the sedimentary micro-facies and remaining oil distribution and suggestions are put forward for the development of residual oil in different microfacies sand bodies.
