桑塔木地区位于塔里木盆地塔北隆起轮南低凸起的中部,是塔里木盆地重要的油气富集区和产油区之一。通过对该地区断裂发育史的解剖,发现桑塔木南断裂和桑塔木北断裂明显分段发育,在油藏形成的两大关键时刻即海西期和喜山期,断裂中、东段强烈活动,西段活动不明显,表明了断裂与油气运聚具有良好的匹配关系,据此提出了本地区油气聚集的规律,即平面上受差异聚集控制,垂向上为油气运移分馏作用所控制。

Sangtamu region,which locates in the central of Lunnan low salience of the Tabei uplift in Tarim basin,is an important area where petroleum enriched and produced.By anatomizing development history of rift in Sangtamu area,the south rift and the north rift development segment,which are different in the west,the middle,and the east.During Hercynian and Himalayan,which are zero hours of hydrocarbon accumulation,rift of middle part and the east part were heavy activity.
