It is shown that Junggar Basin has large exploration potential and the theories and methods for the basins’ exploration can be used for reference mutually. It is concluded that petroleum exploration of Junggar Basin should focus on the study of paleo-uplift, relationship between faults and hydrocarbon accumulation, simultaneous exploration of gas and oil, and Carboniferous volcanic reservoirs.ix = o ns = "urn:schemas-microsoft-com:office:office" />
