Abstract: Mesozoic-Cenozoic foreland thrusting belts occurred in Kuqa and in the southern margin of Junggar Basin, distributed in both north and south sides of Tianshan orogenic belt, whose formation and evolution have heavily affected and controlled the basins distribution, basement property, the scale of sedimentary cover and texture feature of whole basin and late destroying distributed in its both sides. In the process of same one regional stress field, the tectonic evolution and oil and gas geologic condition of Kuqa foreland thrusting belt and the southern margin of Junggar Basin all show much similar characteristics, both of them developed multi-set mature source rocks, and formed multi-set high-quality reservoir-cover combinations, and developed various traps. Because the relation among source rock, reservoir and cover is well matched, providing the material basement for forming large oil and gas fields
