Abstract: Junggar Basin is abundant in natural gas resources, but the exploration degree of its resources is very low, which is only 3.48%, far under the average level of the whole country and all basins in western China, these indicate that enormous exploration potentiality in this basin. The break-through of natural gas exploration and fast growth of the reserves are the key and important guarantee that Xinjiang Oilfield Company will realize sustainable development. By analysis,author believed that the main target of natural gas exploration in the basin is to look for the large-medium gasfields. The abdomen and the south margin of the basin is favorable area to form the high-temperature pyrolysis gas reservoir and coal-type gas reservoir. On the basis of this research, risk analysis for natural gas exploration have carried on various areas in Junggar Basin, and guiding suggestions and measures on how to break through natural gas exploration and ensure fast growth of natural gas reserves in the future are proposed.
