从地质学及地层学的发展趋势上看,动力层序地层学是层序地层学发展的方向。动力层序地层学研究的基本思路是不同构造演化阶段层序发育的主驱动力是有规律地变化演进的。以裂谷型的渤海湾盆地渤海海域为例,以断陷期的沙河街组、断拗期的东营组、拗陷期的明下段为典型代表,阐述了不同构造演化阶段层序发育主驱动力从构造活动到湖平面变化再到气候变化的规律性演进及其对各时期层序结构独特的控制作用。从动力层序地层研究的角度回答了包括层序内部划分、强制湖退、层序识别标志等几个陆相层序地层的关键问题。动力层序地层学研究对渤海油气勘探起到了很好的指导作用,并指出了下一步规模型隐蔽油气藏的勘探方向。
From the development trend of geology and stratigraphy, dynamic stratigraphic stratigraphy is the direction of the development of sequence stratigraphy. The basic idea of motivation sequence stratigraphy research is that the main driving force of sequence development in different tectonic evolution stages changes regularly. Taking the Bohai Sea basin in the rift-type Bohaiwan basin as an example, the Shahejie Formation in faulted-down period, the Dongying Formation in the fault-depression period and the Ming lower part in the depression period are typical representatives. The main driving forces of sequence development in different tectonic evolution stages The regular evolution of forces from tectonic activities to lake level changes to climate change and their unique control over the sequence structure in each period. From the perspective of dynamic stratigraphic stratigraphy, the key questions including stratigraphic sequence stratigraphy such as sequence division, forced lake retreat and sequence identification mark are answered. The study of dynamic sequence stratigraphy plays a very important guiding role in Bohai oil and gas exploration, and points out the exploration direction of scale subtle reservoirs.
