| 摘 要： | 南堡凹陷在古近纪是一个"北断南超"的断陷构造,东营组主要发育(扇)三角洲—湖泊相沉积体系,对于其南部地区的地层等时格架研究尚未深入。依据高分辨率层序地层学原理,综合岩芯、录井、测井以及地震资料,识别出南堡凹陷东营组内的4个基准面旋回,将南堡凹陷东营组划分为1个长期旋回、4个中期旋回及多个短期旋回,并对各界面和层序的测井响应、地震反射特征、短期旋回叠加样式及沉积相特征进行了分析,初步建立了南堡凹陷南部的等时地层格架。

| Abstract: | High resolution sequence stratigraphy research has been carried on in Nanpu Sag,which was a rift lake in Paleogene Period.Mainly sedimentary systems in this area are fan-delta deposit and lacustrine deposit.Using the data from core,well logs and seismic reflection,three base-level cycles and their characteristics have been recognized and analyzed.There are one long base-level cycle,four medium base-level cycles,and a number of short base-level.Based on the recognition of base-level cycles,the high resolution stratigraphy frame has been built up. |

| Keywords: | high resolution sequence stratigraphy base-level cycle stratigraphic frame Paleogene Napu Sag |
