济阳坳陷中生界层序地层研究
|
摘要
济阳坳陷是渤海湾盆地的西南部的重要的含油气盆地。该盆地是1个中、新生代叠合盆地,是在华北古生代地台基础上发育而成的。论文在前人研究成果的基础上,通过大量钻孔、地震剖面、测井等资料,运用层序地层学的理论与分析技术,结合研究区盆地演化和构造运动特征,识别和对比了层序界面,识别了层序界面,划分了6个三级层序,每个三级层序由三元结构组成:下部的低水位体系域(LST)、中部的水进体系域或水域扩张体系域(TST)、上部的高水位体系域或盆地萎缩体系域(HST)。
Jiyang depression located at the southwest of Bohai basin is an important petroliferous basin in the east of our country.The basin,which developed on the Paleozoic platform of the north China,is a Mesozoic and Cenozoic superimposed basin.On the basis of comprehensively analyzing the seismic data,well logs and core data,and combining characteristics of basin evolution and tectonic movement in the study area,this paper identified and compared the sequence interfaces in Mesozoic of Jiyang depression,and divided it into six third-order sequences,which is composed with three components: the lowstand systems tract(LST) in the lower part,transgressive system tract(TST) in the middle part,and highstand systems tract(HST) in the upper part.
