摘　　要：为搞清汤原断陷油气藏的分布规律，指导下步油气勘探，从研究汤原断陷构造演化过程的研究入手，结合钻探情况，分析了断陷的构造演化过程及其对油气成藏的控制作用。认为该断陷在古近纪经历了初始断陷、强烈断陷、断凹转化和断陷消亡的过程，随之充填了多套生、储、盖组合，伴随断层的幕式活动，形成了逆牵引背斜、断块、断层遮挡和断层-岩性等多种类型油气藏。指出了逆牵引背斜油气藏主要分布在东部凹陷带控盆断裂附近，断块、断层遮挡和断层-岩性等油气藏主要分布在构造复杂的中央隆起带，对进一步加大汤原断陷油气勘探具有一定的指导作用。In order to make sure of hydrocarbon reservoir distribution laws in Tangyuan Rift and guide next oil/gas exploration, beginning with studying the tectonic evolution course in Tangyuan Rift, and combining drilling situations, this paper analyzes the tectonic evolution course in Tangyuan Rift and its control on hydrocarbon reservoirforming. It is believed that in Paleogene the rift has experienced the courses of initial rift, strong rift, rift-depres- sion conversion and rift consumption, soon afterwards multiple sets of source-reservoir-cap combination were filled, accompanying with the episodic action of faults, multiple types of hydrocarbon reservoirs, such as rollover anticline, fault block, fault barrier and fault-lithology were formed. It is pointed out that the rollover anticline hydrocarbon reservoirs mainly distribute near the faults controlled by the east hollow zone, the hydrocarbon reservoirs including fault block, fault barrier and fault-lithology mainly distribute on the central uplift belt with complicated structures, which has a certain guide action for strengthening oil/gas exploration in Tangyuan Rift.
