| 摘 要： | 东营凹陷北带中段，主要指胜北-利津断裂带两侧，包括利津、宁海、胜北3个地区。文章涉及的研究对象主要为与北带砂砾岩扇体相关的地层，即沙四上亚-段沙三段。根据Cross（1998）的高分辨率层序地层学理论，笔者对区内沙四上亚-段沙三段进行了详细的层序地层研究。在连井剖面层序地层对比的基础上，建立了该区的高分辨率层序地层格架，并在此基础上，探讨了该区砂砾岩扇体的沉积演化特征和时空分布规律。

| Abstract: | The middle section of the north belt of Dongying depression is mainly indicated the both sides of the Shengbei-lijin rift, including Lijin, Ninghai, Shengbei areas. The study strata are upper sha-4 sha-3 member of sandstone-conglomerate bodies in the north belt. Based on the detailed sequence stratigraphy research, high-resolution sequence stratigraphic framework is established for sha-3 member by using the theory of sequence stratigraphy and comprehensive analysis of seismic, logging, and coring data with the comparison of sequence stratigraphy of the connected wells profile. The constitution and evolution characteristics, distribution rule of sandstone-conglomerate bodies are also studied under the established high-resolution sequence framework. |
