| 摘 要： | 介绍了流体包裹体分子成分 (MCI)分析技术及其特点 ,以塔里木盆地英南 2气藏为例 ,利用 MCI技术及其研究方法进行油气成藏期次的研究。对塔里木盆地英南 2现今气藏储层中的烃类 (凝析油与储层沥青 )以及气藏志留系与侏罗系储层成岩矿物中的含油包裹体分子进行了地球化学成分分析 ,对比研究含油包裹体分子地球化学成分和现今气藏中的烃类的分子地球化学成分。研究表明油包裹体分子成分与原油和储层沥青分子成分相似 ,反映它们来源相同 ,是同一期烃类充注的产物 ,英南 2气藏油气成藏期次为一期

| Abstract: | The analysis method of molecular composition of inclusions(MCI) and its characteristics are introduced,and the MCI analysis method is applied to the determination of the charging episodes of the Yingnan2 gas reservoir in the eastern region of Tarim Basin. The molecular geochemical characteristics of the condensate oil and reservoir asphalt in the present gas pools of the well Yingnan2 are described,and the molecular composition of the oil-bearing inclusions in the diagenetic minerals of the Silurian and Jurassic gas reservoir is analyzed and compared with that of the oil and hydrocarbon in sandstone reservoir rock. The results show that the geochemical characteristics of both hydrocarbon inclusions and hydrocarbon in sandstone reservoir rock are similar and they accumulated all in one time. |
