Abstract: Based on the geological data and seismic information, the geological structures and fill characteristics in peripheral uplift belts of Junggar basin were analyzed and summarized, and the space allocations of traps, source rocks and transport systems were studied. It is pointed out that three vertical evolution types of continuous uplifting, depression followed by uplifting and repeated uplifting and depression occur with corresponding three geological structures. The continuous uplifting type is characterized by the space allocation of “trap beside source rock”, the others by “trap on source rock”, “trap together with source rock” and “trap beside source rock”, and the different trap-source rock allocations are of different transport systems. Under the effects of the development characteristics of trap, source rock, transport system and their space allocations controlled by different geological structures, the peripheral uplift belts have three types of hydrocarbon accumulation patterns. It is concluded that the southern Chepaizi, Hala’alat-Hongqiba and Mulei areas in the peripheral uplift belts of Junggar basin could be the favorable targets for petroleum exploration in the future
