| 摘 要： | 本文采用地震和钻测井资料，建立了松辽盆地北部浅层的层序地层格架，分析了各体系域内沉积相的特征。在此基础上，研究了储层和盖层的发育特征，并探讨了储盖组合的配置关系。认为储集岩主要为四方台组层序格架中的湖侵体系域河流相砂岩和湖退体系域中的三角洲相砂岩及滨浅湖滩坝砂岩，平面上主要集中在齐家，古龙凹陷、龙虎-大安阶地、长垣南部和三肇凹陷等地区。盖层主要为每一层序中最大湖泛面上下的稳定泥岩段，其中四方台组下部层序中的泥岩段为局部盖层，四方台组中上部及明一段层序中的泥岩段为较有利的区域盖层。

| Abstract: | In the light of seismic data and well logs, the present paper deals with the construction of the sequence stratigraphic framework in the shallow strata, analysis of the sedimentary facies in individual systems tracts, and development of the reservoir rocks and seal rocks and their disposition in northern Songliao Basin. The reservoir rocks consist of fluvial sandstones in the transgressive systems tract, and deltaic sandstones and littoral and shallow lake beach-bar sandstones in the regressive systems tract in the Sifangtai Changyuan and Sanzhao depression. The seal rocks are composed of mudstones above or below the maximum flooding surface in individual sequences. The mudstones in the lower sequences of the Sifangtai Formation are only regional seal rocks, while those in the middle and upper parts of it and those in the sequences of the first member of the Mingshui Formation are considered as relatively favourable seal rocks. |
