摘要
基于地质、地球物理特征分析,研究了济阳坳陷第三系内部发育的多个地层不整合的样式。着重探讨了不整合面上、下地层的接触关系及微观组构,提出了一种新的有关不整合宏观样式的划分方案;认为济阳坳陷第三系内部的不整合可划分为4类宏观构建样式、16种地层不整合结构类型。以此为基础,进而分析了不整合结构对圈闭、输导、封盖的控制作用,并建立了第三系不整合油气藏分布模式,探讨了地层不整合油气藏的勘探部署经验。
Based on an analysis about the geological and geophysical characteristics, the unconformity styles developed in Tertiary in Jiyang depression were studied. The stratigraphic contact relationships, the unconformity relationships and their microscopic constitutions were discussed, and a new classification scheme based on macroscopic style of unconformity was suggested in the paper. In the paper the unconformity in Tertiary in Jiyang depression was divided into 4 macroscopic structural styles, and 16 unconformity configuration types. Based on these research re- suits, the controlling effect of unconformity configuration to oil-gas migration and accumulation was analyzed, the Tertiary unconformity reservoir distribution mode was established, and the exploration and deployment practice of such kind of reservoir were discussed.
