Abstract:

Seism ic，drilling，logging and test data are integrated to systematically study the provenances and paleocurrentdirection through analysis ofpaleogeomorphology，net-to-gross ratio，stratigraphic dip and lithic components for the Shawan Formation of the Chepaizi uplift in Junggar Basin.The result indicates that there are two major provenances，one in the northwest and the other in the northeast.The early provenancewas developed early and controlled the near S-N distribution of the sandbodies.Later itm igrated eastwards，mainly northeastwards，and controlled the NE-SW distribution of sandbodies.
