摘要
根据昌参 2井 2 0 1 0 8m和 2 0 1 5m两个含油样品多项地球化学分析资料综合判断 ,上侏罗统九佛堂组原油属于成熟原油 ,具有六高、七低、一轻的地球化学特征。应用本井各组段油、岩族组成 ,饱和烃色谱 ,甾、萜生物标志物 ,碳同位素等项资料数据对比结果 ,认为该原油与阜新组、沙海组及九佛堂组下部烃源岩不相关 ,而与九佛堂组上部湖相烃源岩有良好的亲缘关系 ,属于自生自储 。
Based on the geochemical analyses of two oil sa mp les from intervals at 2010.8 m and 2015 m of Well Cangcan 2, the oil from Jiufot ang Formation of Upper Jurassic is classified as a matured oil with the charact eristics of'six highs', 'seven lows', and 'one light'. According to the co rrelation results of oil aod rock group compositions,chromatography of saturated alkanes, biological markers of steroid and terpinoid, and isotopes of Carbon, t he oil is believed to have little relation with the source rock of Lower Jiufota ng Formation but much in common with the lacustrine source rock of Upper Jiufota ng Formation. It is originated and accumulated in place with short-distant migr ation.
