笔者应用层序地层学的基本概念和研究方法初步解释了松辽盆地南部上侏罗一下白垩统的层序,──4个层序可从地震剖面和钻井资料中解释,每个层序又可进一步划分出3种体系域。体系域的沉积和岩相的分布明显受构造沉降为主、水面升降为辅的双重控制。同时建立了两种层序地层格架,指出具有十屋断陷型地层格架的断陷盆地生储盖配置良好,有较好的油气潜力。
Based on the basic concepts and research methods of sequence stratigraphy, the author initially explained the sequence of the Upper Jurassic Cretaceous in the southern Songliao Basin - four sequences can be explained from seismic data and drilling data. Each sequence Can be further divided into three kinds of system domain. Sedimentary and lithofacies distribution in the system are obviously dominated by tectonic subsidence and secondary control by surface lift. At the same time, two kinds of sequence stratigraphic frameworks are established. It is pointed out that the fault reservoirs and caps of the fault basin with the Shiwu fault-depression stratigraphic framework are well arranged and have good hydrocarbon potential.
