为了对辽河坳陷东部凸起的下古生界进行层序地层学研究，综合野外剖面、钻井、测井、二维地震剖面资料，将其划分为１ 个一级层序、２ 个二级层序和１３ ～１４ 三级层序，从而建立起该地区下古生界的层序地层格架。通过大量室内薄片鉴定和相关测试资料分析，结合层序的发育特征可知本地区的生、储、盖层与层序的形成密切相关：生油层主要位于层序的凝缩段以及与凝缩段紧邻的海侵体系域晚期和早期高水位体系域中；储层主要位于高水位体系域中；盖层则在各个体系域均有分布。
In order to conduct a sequence stratigraphic study of the raised Lower Paleozoic in the eastern Liaohe Depression, the data of the field profile, drilling, well logging and 2D seismic sections are divided into one first-order sequence and two second-order sequences Sequence and 13 ~ 14 third-order sequences, so as to establish the sequence stratigraphic framework of the Lower Paleozoic in the area. Through a large number of indoor thin-film identification and related test data analysis, combined with the development characteristics of the sequence shows that the region of the reservoir, caprock and the formation of the sequence is closely related to: the oil layer is mainly located in the condensate section of condensation and condensation section In the late and early highstand systems tract of the adjacent transgressive system tract; the reservoirs are mainly located in the highstand system tract; the capstones are distributed in all the systems tract.
