| 摘 要： | 根据Vail的层序地层学理论,建立了渤海下第三系层序地层沉积模型.将下第三系分为3个层序,3个层序具有相同的结构、沉积环境、接触关系等特征.每个层序内有3个重要界面,分为4个体系域,体系域边界及体系特征可大范围追踪对比.渐新统的体系域又划分出准层序组、准层序.研究表明不同体系域的储层特征明显不同,油气分布与层序相带有关.

| Abstract: | Based on vail's sequence stratigraphic theory,the sequence stratigraphic model of Paleogene in Bohai Area is divided into three sequences with same configuration,sedimentary environment and contacts. Within each sequence,there are four systems which are defined by three significant sequence surfaces and can be widely traced. Moreover,Oligocene system is also subdivided into sub-sequence or sub-sequence group. However,the study result shows that each system has its special characteristics and the hydrocarbon disribution is associated with sequence facies. |
