Abstract: Based on the sequence stratigraphy theory, through the comprehensive analysis of geological, seismic,drilling, logging and outcrops of Neogene Miocene Shawan group strata of Chepaizi Area in the Junggar Basin,
Neogene Shawan group can be divided into two third-sequences from the bottom to the top: N1SSQ1 and N1SSQ2.A total of 3 third-sequence boundaries are identified. Through identifying and comparing the unconformity surface,conformity, the initial lake flooding surface and the largest lake flooding surface, etc., beginning with the study of sequence division, the identifying characteristics of the system tract and parasequence sets boundary are analyzed deeply, the isochronous sequence stratigraphic framework of the study area is set up.

Key words: Chepaizi Area, Neogene, Shawan formation, sequence boundary, system tract
