摘　　要：研究了依据地层基准面原理进行开发调整阶段储层精细对比的方法 ,总结了地震、钻 /测井基准面界面及地层响应特征和识别方法。以湖泛面为层序界面 ,在濮城油田沙三中 6 10油藏内识别出超短期、短期、中期和长期四级界面和基准面旋回 ,其中长期旋回相当于水下扇复合体 ,中期旋回相当于水下扇朵体 ,而短期旋回相当于水下扇叶体 ,短期旋回是油藏细分开发调整的最小单元。在原来 5个砂组的基础上 ,经研究划分了 6个中期旋回和 2 7个短期旋回。在对断陷湖盆及水下扇形成的水动力过程分析的基础上 ,总结了水下扇形成过程中基准面旋回演化模式。Pucheng oil field is located in the Dongpu depress, Henan province. In this study, a method based on baselevel analysis for stratigraphy correlation in the development stage is provided. The characteristics of stratigraphic surface and stratigraphy sequence in the seismic, well log and cores are summarized. Four scales of sequence cycles are distinguished in the study area, including very short term cycle, short term one, middle term one and long term cycle. Long term cycle is corresponding to sub fan complex, and middle cycles to fan slove, and short one to fan lobe, which is the smallest units for adjusting in the production. In the study zone, 6 medium term and 27 short term cycles are distinguished and correlated.
