摘  要:通过连续取芯井的岩芯观察,以及录井、测井、古生物资料,运用沉积学理论,丰富和发展了原有济阳坳陷孤岛油田馆陶组仅仅普遍发育河流相的沉积观点,指出馆陶组上段不仅发育辫状河、曲流河等河流相,还发育曲流河浅水三角洲-氧化型浅水湖泊沉积体系,分析了浅水三角洲、浅水湖泊沉积特征和微相划分,并将湖相沉积模式应用于孤岛油田馆上段小层对比和寻找剩余油。Mainly by means of taking the observation and description of core of continuous coring well,and compre-hensive study of well logging,well survey and palaeophyte data,with the exercitation of sedimentology theory,this paper enriched and developed the intrinsic sedimentary viewpoint of that the Guantao formation of Neogene of Gud-ao oilfield only widely contains river facies.This research suggested that the upside Guantao formation developed not only braid river and meandering river but also shallow water lake delta and shallow water lake.Lacustrine deposi-tional model was extensive applied in member correlation and residual oil searching.
