Using the theories and methods of sequence stratigraphy and modern sedimentology, emphasizing the overall research of the whole basin, the authors analyzed seismic data, logging and drilling core data of Triassic in Tarim Basin and identified the boundaries of sequences and system tracts. And five sequence boundaries with isochronous are developed and four third-order sequences are divided. According to division of internal structure, a unified sequence stratigraphic framework between well and seismic is established in platform area.
