Abstract: The study of the structural features and the hydrocarbon distribution in Shixi oilfield of Junggar basin shows that the large?scale differential rising creates the stretching of the Jurassic, forming the drape anticline, at the same time, shaping extension normal faults at the transfer zones of its flanks. In the process of rising, the Jurassic system at relatively uplifting area tends to form high potential domain of flu?id under squeezing action, which leads to the fact that the hydrocarbons migrated by the faults/fractures opening are difficult to enter the traps for accumulation. By the end of the rising, the hydrocarbons migrating along updip direction of the slope are normally blocked by the closed faults/fractures. This could be the reason why the hydrocarbons are generally accumulated in the traps of downthrow blocks of the faults at relatively low structural positions in Shixi oilfield
