In southern margin of Junggar Basin, through a lot of cores of 13 wells describing, reservoir studies and some results of vitrinite reflectance analyzing, there are 3 different factors of reservoir at segmentations and zones in Tertiary. They are different porosity, permeability, compositional maturity and textural maturity. In different segmentations and zones as a research unit in thrust belt, the controlling factors of the different reservoir include: 1) different sedimentary feeders and sedimentary facies and different sandstone body that belonging at the same sedimentary facies; 2) different lapidofacies, clay and cement that located at inter-grain and dissolution in reservoir; 3) the main controlling reservoir is buried thermal effect and not the tectonic compression in Palaeogene; and 4) because of the Tianshan Mountain’s uplifting in Neogene the tectonic compression changes the main controlling factor of reservoir in southern margin of Junggar Foreland Basin.
