摘　　要：准噶尔盆地石西油田侏罗系构造特征和油气分布研究发现,大规模的差异隆升造成侏罗系引张,在形成披覆背斜的同时,背斜翼部转换带部位形成了张性正断裂,同时也是造成油气分布在构造相对低部位的重要因素。隆升过程中,相对隆起区的侏罗系在挤压作用下形成流体高势能区,导致断层开启时输导的油气难以进入圈闭成藏,隆升结束后断层封闭,遮挡沿斜坡带上倾方向运移的油气,从而使油气在相对低部位断层下降盘的圈闭内聚集成藏。The study of the structural fealures and the hydrocarbon distribution in Shixi oilfiehl of Junggar hasin shows that the large-scale differential rising creates the stretching of the Jurassic, forming the drape anticline, at the same lime, shaping extension normal fauhs at the transfer znes of its flanks. In the process of rising, the Jurassic system at relatively uplifting area tends to form high potential domain of fluid under squeezing action, which leads to the fact that the hydrocarbons migrated by the fauhs/fractures opening are diffieuh to enter the traps for aumulation. By the end of the rising, the hydrocarbons migrating along updip direction of the slope are normally hloeked by the closed fauhs/fractures. This could be the reason why the hydroearbons are generally accumulated in the traps of downthrow blocks of the faults at relatively low structural positions in Shixi oilficht.
