Abstract: Seismic facies analysis of the Middle and Upper Jurassic formations in the Shengbei (SB)area of the Turpan-Hami basin was made on the four seismic parameters-frequency, amplitude, continuity and reflection structure. The map illustrating the seismic facies of the area was also drawn. The seismic facies has been transferred into the sedimentary facies after a comprehensive interpretation. It is shown that alluvial fan, flood plain, fan delta, braid river delta and lake were the main sedimentary facies in the SB area of the Turpan-Hami basin during middle and late Jurassic times.
