【摘要】 以塔里木盆地英南2井气藏为例,用流体包裹体进行油气成藏期次的研究。镜下观察流体包裹体,并对与烃类共生的盐水包裹体进行均一化温度和冰融点测试,进行油气藏成藏期的分析。流体包裹体分析表明英南2井气藏多为气态烃包裹体,大部分存在于石英次生加大边中,共生的盐水包裹体的均一化温度集中且接近现今井温,对比埋藏史得出:天然气是在近10Ma时一次性充注成藏。更多还原

【Abstract】 Taking Yingnan-2 oilfield in the eastern region of the Tarim Basin, the paper focuses on the application of fluid inclusions to determination of times and stages of hydrocarbon accumulation history. Besides microscopic analysis of fluid inclusions, measurement and analysis of the homogenization temperature and the melt temperature have been carried out for times and stages analysis of hydrocarbon accumulation history. The results show that most of fluid inclusions are aqueous fluid inclusions with high maturity and the homogenization temperature is centralized, which means hydrocarbon are accumulated all at one time. Combined with the burial history, it is concluded that hydrocarbon is accumulated within 10 Ma.更多还原
