Abstract: During Late Carboniferous to Early Permian, Junggar Basin's hinterland area has orderly formed a northwest-oriented depression- uplift structural framework on the Pre- Cambrian crystalline basement, which controls generallythe spatial distribution of Permian as a main hydrocarbon source rock and position of favorable oil and gas accumula-tion belts in this basin. In the period of Middle- Late Jurassic, formation of northeast-oriented low-range uplift 2one oc-curred in the hinterland, becoming a prospecting domain of shallow-layered Jurassic system.it covers a big area of source sag and has developed multi- stratified hydrocarbon source rocks. Analy sed fromgeneration, migration, accumulation and preservation of oil and gas, Mosuowan uplift,Sannan uplift, Dabasong uplift,Mahu anticline, Baijiahai uplift become favorable areas for Prospecting hydrocarbon recently. In addition, Luiian sagand Paotai uplift will act as successor domains from now on.
