%X Incised valley is an important kind of depositional system in the
Chepaizi area, west Junggar Basin. In this paper, incised valley depositional
system and its prospect direction in the area were obtained with the analysis
of seismic reflection, depositional and logging characters. The results show
that the Chepaizi uplift Jurassic developed four kinds of filling modes
including vertical aggradation, side aggradation, disorder and compound mode
and three kinds of distribution type including unitary type, multiple branch
type and disorder type. The fault-lithological trap can be easily formed in the
updip direction of the valley with the seal of thrown side of fault, which is
the main trap type in the area. Incised valley system has been confirmed to
have well hydrocarbon shows, yet no industrial output was gotten. The LST fan
in the underwater zone of the incised valley system in the east and south
margin of the Chepaizi uplift is the important prospect direction.
