| 摘 要： | 依据英南2井天然气组分特征、碳同位素特征及成藏时间等方面的研究,对英南2气藏成因进行了探讨,认为英南2气藏为一经后期调整的次生气藏.天然气为奥陶纪晚期一志留纪早期生成并保存在志留系和奥陶系上部储层中的凝析气、原油伴生气和加里东末期生成的干气的混合气,也可能有一些原油裂解气的混入.石油伴生气和凝析气是英南2井天然气高氮、...

| Abstract: | According to the study on components and its isotopes of natural gas in Yingnan 2 gas reservoir and the formation time,the paper discuss the genesis of Yingnan 2 gas reservoir,and reckon that it is a secondary gas pool formed by adjustment in the geologic history.The gas in Yingnan 2 gas pool is commixed by condensate gas,associated gas,kerogen cracking gas,and oil cracking gas.The condensate gas and associated gas are the main components and the key cause of high N2 and fixed hydrocarbon contents. |
