摘要
In this paper, the authors studied the sedimentary characteristics of Triassic in Che-Guai area, northwest margin of Junggar Basin. The authors found that conglomerate and sandstone mainly develops. The primary provenance is from northwest margin, and the secondary source area is the from west area of Well C45. From early to late stage, the transgressive sedimentary characteristic of Triassic dominantly controls the distribution of high quality reservoir.
