Characteristics of the Incised Valley in the Jurassic of the West Junggar Basin and Its Prospect Direction, NW China


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.
