摘　　要：依据高分辨率层序地层学原理,研究了泉三、四段地层的岩石学和地球物理学等特征,准确识别出层序界面、湖泛面和基准面升降旋回等层序标志特征。将泉三、四段地层划分为三级层序1.5个对应3个基准面升降旋回、四级层序7个对应14个基准面升降旋回,较好地解决了泉三、四段地层6个油层组与层序地层的对应关系,最终建立了松辽盆地泉三、四段地层高分辨率等时层序地层格架。According to the basic principles of high-resolution sequence stratigraphy, the characteristics of petrology and geophysics of Quan No. 3 and NO. 4 members have been systematically explored and the marked sequence features of sequence interface, lake flood plane and the rising-falling cycles of datum level and so on have been accurately recognized. The classification of the following （ divides the above two members into 1.5 third sequences corresponding to 3 level cycles and 7 forth sequences relating 14 level cycles） can much better solved the corresponding problem between the 6 oil layers of above two members and sequence formations, finally the high-resolution isochronal sequence stratigraphic framework of the above two members in Songliao Basin can be established.
