摘要：

高邮凹陷戴南组是在先水进、后水退的背景下形成的一套先上超、后充填的沉积,构成一个完整的沉积旋回,反映了由湖相向河流相转化的演变过程。在其西、南、北部分别发育三类不同的三角洲体系。

Abstract:

The Dainan Formation in the Gaoyou Depression is a complete sedimentary cycle. It consists of lacustrine facies in an onlapping style at the lower partand fluvial facies at the upper part in a filling pattern, showing a evolution-ary process from lacustrine to fluvial facies. The various sedimentary systems as Majiazui-Lianmengzhuang long-axialdelta, Zhenwu - Caozhuang fan-delta and Zheduo delta are respectively inthe west, south steep slope and north gentle slope of the depression. Amongthem, the fan delta and long-axial delta systems are favourable for hydro-carbon accumulation.
