摘　　要：明确轮古地区流体包裹体特征与油气成藏过程.通过对轮古地区的岩心样品岩石学观察、流体包裹体系统分析测试和原油荧光测定,结合均一温度-埋藏史投影法,并模拟烃源岩生烃史,恢复油气成藏过程.结果表明,轮古地区奥陶系发育三期油包裹体,分别发黄褐色、黄绿色和蓝色荧光,伴生的盐水包裹体均一温度范围分别是70~100℃、80~110℃、100~120℃.全区三期油包裹体对应3个充注期,分别是加里东晚期-海西早期、海西晚期和喜山期.轮古西部地区的原油的主充注期为加里东晚期-海西早期,轮古中部地区的原油的主充注期为海西晚期,轮古东部地区的原油的主充注期为喜山期.The fluid inclusion characteristics and hydrocarbon accumulation process in Lungu area were clarified.Based on the petrological observation of core samples in Lungu area,the analysis and testing of fluid inclusion system and the fluorescence measurement of crude oil,combined with the homogeneous temperature and burial history projection method,the hydrocarbon generation history of source rocks was simulated to restore the hydrocarbon accumulation process.The results show that there are three stages of oil inclusions in the Ordovician in Lunku area,which are yellow brown,yellow green and blue fluorescence,respectively.The homogenization temperature of the associated saline inclusions ranges from 70℃to 100℃,80℃to 110℃,and 100℃to 120℃,respectively.The three stages of oil inclusions in the whole area correspond to three charging periods,which are Late Caledonian-Early Hercynian,Late Hercynian and Xishan.The western region of Lungu is dominated by Late Caledonian and Early Hercynian oil,the central region of Lungu is dominated by Late Hercynian oil,and the eastern region of Lungu is dominated by Himalayan oil.
