Abstract:

A seismic-stratigraphic project concerning the Upper Triassic divisionand correlation in central and west Sichuan Basin is proposed in this paperaccording to seismic-stratigraphic method.Based on this project,the authorhas got a new understanding on basin-formation texture,facies distribu-tion,the type and distribution of reservoir sandbodies in the Late Triassic,and also proposed some new targets for oil and gas prospecting.
