摘要
由于东部凹陷大平房—桃园地区沙河街组沙三段地层地震资料以及储层特征不清等原因影响了该区的勘探发现,为了进一步加快该区的勘探程度,通过对该区地震、钻井、测井和岩心等资料综合分析研究,建立了沙三段岩石地层、地震地层和测井地层对比格架;详细划分和描述了沙三段内部层序、体系域和界面,识别出2个三级层序界面、3个体系域及2种准层序组类型;建立了沙三段沉积体系、沉积相发育和展布在内的层序地层格架。
In order to enhance the efficiency of exploration in the Dapingfang-Taoyuan region of the East Depression of the Liaohe Basin, seismic data and reservoir characteristics were restudied in this paper. Lithostratigraphy, seismic stratigraphy and sequence stratigraphy of the Es3 of Shahejie Formation were established. Upon the three 3rd order sequence boundaries, 3 system tracts and 2 types of parasequences recognized, the authors established the depositional systems and the sequence sytratigraphic framework, which are proven useful for exploration in the region.
