通过对扶新隆起带北坡泉三段河流相地层开展高分辨率层序地层研究,在对短期基准面旋回相序特征和中期基准面旋回河道类型演化分析的基础上,根据基准面及河流水位的变化对研究区目的层进行了体系域的划分,并进一步建立了层序地层模式。

High frequency sequence division and correlation are conducted for the fluvial formation in the third member of Beipoquan in Fuxin uplift zone by using high resolution sequence stratigraphy theory.The system tract is divided and stratigraphic model is established for the study area according to base level cycle,river stage,fa- cies sequence of short - term base level cycle,and channel evolution of medium - term base level cycle,thus providing sequence - stratigraphic framework of isochronous significance for channel sand prediction,sedimentary mierofacies analysis and the comprehensive study of hydrocarbon accumulation.
