摘　　要：通过10余口钻井岩心观察、描述,结合岩性、沉积构造、剖面结构等识别标志研究,在中央隆起带东河塘组中识别出前滨、临滨和三角洲;根据进一步的沉积相特征和井间沉积相对比研究,系统编制了中央隆起带东河塘组下砂岩段和上砂岩段沉积相平面分布图,研究了其沉积相平面分布及垂向演化特征。Observated and descripted more than 10 holes drilling cores, combining with the lithology, sedimentary structure,profile structure identification research,in the central uplift belt in Donghetang formation to identify the foreshore and shoreface and delta;According to the characteristics of sedimentary facies and interwell sedimentary further contrast research, the system is compiled under the Donghetang group in the central uplift belt of sandstone and sandstone on the plane distribution of sedimentary facies ,and study the planar distribution of sedimentary facies and the vertical evolution characteristics.
