Abstract: We consider that the oil source bed in the east of Junggar Basin is mainly of the upper Permian series. The oil and gas accumulation in front of the Kelameili Mountain of the northern Part of this basin is mainly of the P_2p³⁺³ controls the distribution of oil and gas abundance obviousty. In the southern part in front of the Bogeda Mountain. there are two oil and gasaccumulation zones can be predicted : 1) The east part: the Beisantai area has been confirmed; 2) The west part: the Fukang and Gumudi area have become exploration target already. Some new oil and gas fields can be discovered in the near futrue.
