Abstract: In the light of the latest heavy oil exploration progress in the Permian formation of Huoyanshan central zone, TurpanHami basin, this study on heavy oil origin and reservoir formation is carried out based on geologic and geochemical data. It is concluded that Shengbei depression is the major source area for the central heavy oil zone, biologic degradation is the major cause of the oil thickening, and the Triassic heavy oil reservoir in Well H8 was formed at the end of Xishanyao depositional stage in MidJurassic epoch. In addition, the forming mode of this kind of reservoirs “secondary influx” is described through revealing the heterogeneity of the reservoir of Upper Permian and MidJurassic system in Well Y2 and Y4
