摘　　要：松辽盆地北部双城南地区登娄库油层是新发现层系,以往工作中对该区域的研究较少。以松辽盆地北部双城南地区原地层格架为基础,充分利用双城南地区测井、录井资料,结合二维地震勘探处理资料,以层序地层学理论、经典沉积理论和构造理论等方法为指导,系统研究该区地层格架及层序分布特征。本区共识别出5套9个标志层,根据垂向上达到单期河流旋回的原则,将登三段地层分为20个沉积时间单元,建立松辽盆地北部双城南地区登三段地层高精度层序地层格架,深化对研究区新层系的地质认识,为后期的勘探部署打下坚实的地质基础。Denglouku oil layer of southern Shuangcheng Area in the northern Songliao Basin is a newly discovered layer system,and there has been little research on this area in previous work.This topic would be based on the original stratigraphic framework of the southern Shuangcheng Area in the northern Songliao Basin,made full use of logging and mud logging data in southern Shuangcheng Area,combined with two-dimensional seismic exploration processing data,and use sequence stratigraphy,classical depositional theories and structures.Guided by theory and other methods,systematically study the stratigraphic framework and sequence distribution characteristics of the area.A total of 5 sets of 9 marker layers had been identified in this area.According to the principle of reaching a single-phase river cycle in the vertical direction,the Deng-3 Formation was divided into 20 sedimentary time units,and the high-precision strata of the Deng-3 Formation in southern Shuangcheng Area in the northern Songliao Basin are established.Sequence stratigraphic framework,deepen the geological understanding of the new strata in the study area,and laid a solid geological foundation for later exploration and deployment.
