The authors apply finite element method to the digital simulation of Triassic-Tertiary tectonic stress field in Hongche fault belt, Northwest of Junggar Basin. It is indicate that all of the Triassic-Neogene is under the condition of tension. By exploration, the authors find that the exploration well usually have oil and gas in the strong tensile stress zones where are oil and gas accumulation areas and reservoirs. The strong tensile stress areas of Triassic-Cretaceous in Hongche fault belt is mainly distributed in the northwest edge of Junggar Basin where is located in the tectonic uplifts which develop multi-dimensional and complex fault systems, form a large number of local structural traps, develop a lot of tension and tension-shear fractures, they are ideal tectonic stress field for oil and gas accumulation.
