摘要
CO2 气是一种特殊类型的天然气 ,其成因和富集规律与烃类气有着显著的差别 .运用CO2 气碳同位素、伴生气等地球化学资料 ,探讨了松辽盆地CO2 气的成因 ,分析了CO2 气藏分布与深断裂带、区域盖层、深部侵入岩、火山岩分布关系 ,指出了长期活动的深断裂带、深部热流底辟、良好盖层是CO2 气藏的成藏条件 ,给出了CO2 气藏成藏模式 ,进而指出松辽盆地CO2
CO 2 is a special kind of gas. It is distinctly different from hydrocarbon gas in the genesis and accumulation. On the one hand, the genesis of CO 2 gas is discussed by the information of C isotopic and associated gas of CO 2 gas; On the other hand, the formation condition of CO 2 gas pool is discussed by analysing the relationship of CO 2 gas pool distribution and many geological aspects, such as deep fault belt, regional cover rock, deep intrusive rock and volcanic rock. Deep fault, regional cover rock and deep hot\|fluid diapir body are three main factors that CO 2 gas pool forms. Then, CO 2 gas pool modeling is established and the more exploration direction is pointed out.
