摘要
鄂尔多斯盆地是中国第二大沉积盆地,盆地研究程度已经较高,利用包裹体测温技术对鄂尔多斯盆地东部下古生界山西组进行研究,通过镜下分析,观察薄片所反映的成岩序列以及有机包裹体同期的盐水包裹体均一温度研究成藏时代。通过实验得出,研究区山西组均一温度主要分布在70℃～160℃,其峰值温度应为120℃～130℃。对比研究区的热史可以得出研究区山西组油气充注时间主要是晚侏罗世末期至早白垩世早期(150～130Ma)。
The Ordos Basin is the second large sedimentary basin in China. The paper is based on the inclusions homoge- nzation temperature techniques to study the Shanxi formation in the east Ordos Basin, and analyzes the target Block＇ s slice through microscopic, observes the diagcnetic phenomenon accumulation process. The coeval aqueous inclusions＇ homogeniza- tion temperature can provide a detailed statement about the stratum temperature when the inclusion is captured. The inclusions key homogenzation temperature of Shanxi formation are range from 120℃ - 130℃. It is indicated that the key time of inclu- sion were captured in early cretaceous.
