摘要：

利用三维地震工区的地震资料和钻井资料，通过地震反射轴的仔细解释和追踪，在东营凹陷广利东三维地震工区沙三中亚段识别出10个高频层序，自下而上分别编号A至J，不同高频层序的规模和空间分布存在明显变化。高频层序的A、C、D、G、H、I的规模较大，其余高频层序的分布范围较小。井震对比研究表明，在莱10-3井处，只发育A、D、E、G、I个高频层序。在这10个高频层序发育过程中，发生了4次明显萎缩和2次明显的物源向西迁移过程。高频层序分布区域的萎缩和迁移受湖平面升降和沉积物供应的控制，其中沉积物供应是最重要的影响因素。

Abstract:

Based on 3D-seismic and well logging data, ten high-frequency sequences, i.e.A to J, are recognized in middle part of the third member of Shahejie Formation, Guanglidong 3D-seismic survey region, Dongying sag. This work is carried out through careful interpretation and tracing of seismic data. The size and distribution of different high-frequency sequences are changed in space. Integrated well logging and seismic data indicate that five high-frequency sequences (A, D, E, G and I) developed in the area of well Lai10-3. The high-frequency sequences of A, C, D, G, H and I have a big size, but the other high-frequency sequences have a relatively smaller size. Four lake shrinks and two sediment supply transference to west occurred in the study area during the process of these ten high-frequency sequences developed. The size and distribution of high-frequency sequence are controlled by lakelevel fluctuation and sediment supply, but the most important controlling factor is sediment supply.

Key words: high-frequency sequence, sediment supply, lake-level fluctuation, Dongying sag
