Based on the identification of continental sequence on seismic section and welllogging curve and the characteristics of rocks′ combination and paleontology, the strata of Eogene in Raoyang Depression are divided into three secondorder sequences and ten thirdorder sequences. Thirdorder sequencesⅠ,Ⅱ,Ⅲ,Ⅳ,Ⅴ,Ⅵ,Ⅶ are rift lacustrine basin sequence, and can be divided into three system tracts, that is low stand system tracts, lacustrine transgressive system tracts and high stand system tracts. Thirdorder sequencesⅧ, Ⅸ, Ⅹare fluvial sequence, which can be divided into base level rising system tract and base level falling system tract. Based on the identification and correlation of sequence stratigraphic units, sequence stratigraphy models are established. A primary research on relationship between sequence stratigraphic model has been done.
