利用包裹体测温技术研究分析鄂尔多斯盆地渭北隆起耀县地区的热演化状况，恢复其热演化史，对油气勘探的进一步深入具有重要的理论意义。对目标区块的包裹体切片进行镜下分析，观察薄片中包裹体的形态，大小，包裹体类型及其出现的部位。通过对包裹体测温技术进行测试，测得下古生界背锅山组的均化温度主要集中在140℃~150℃区间内，推测该地区至少经历过一次油气运移与充注的过程。由均化温度的峰值区间结合渭北隆起的生烃史图，得到对应的生烃年限为170~200个百万年之间，即早侏罗世。

Using the inclusions thermometry technology to the Taoqu slope section in Yaoxian district in order to recover Weibei uplift’ s thermal evolution in Ordos Basin, To explore the history of hydrocarbon generation, which is beneficial to do theoretical guidance to prepare for next exploration. Firstly, it analyzes the inclusion slices of the target zones under the micro-scope, and observes the inclusions’ shape size type and its appearing parts in the slices. Then by adopting the inclusions ther-mometry, it gets the result that the homogenization temperature of Beiguoshan Zu of lower Paleozoic mainly is concentrated in the range of 140 -150℃. Therefore, we can speculate that the region has experienced the process of hydrocarbon migration and charge at least one time. Combined the homogenization temperature’ s peak value interval with the hydrocarbon generation history diagram of Weibei uplift, we can get the corresponding hydrocarbon generation period is from 170 million years to 200 million years. That is the early Jurassic.
