摘要 苏北盆地溱潼凹陷东部斜坡带阜宁组三段属于古近系充填层系中的晚古新统层系组,为高水位体系域沉积,沉积相组合为三角洲前缘相-包括前缘近端坝、远端坝、分流间湾相砂体夹浅湖-半深湖相泥岩互层。反演结果表明,砂体波组在侧向上具不均一性,指示了自东向西进积沉积特征。砂组空间分布具有继承性。 Member 3 of Funing Formation in eastern slope belt of Qintong Sag is the highstand systems tract,which belongs to the late Palaeocene series depostion of the Paleogene system.The sedimentary facies is delta front which includes the proximal bar,the distal bar,the interdistributary and the shallow to half-deep lacustrine facies clay.The characteristic of composite wave of the sand is inhomogeneity in the inversion section,which shows the trendency of progradation from east to the west.The deposition of sand ...
