It can be established the relationship model between the methane carbon isotope and resource maturity if the gas pool has the same charging period and accumulation effect. 对于天然气充注历史和累积效应大体相同的气藏,通常可以建立天然气甲烷碳同位素(δ13C1)与其成熟度(源岩)的关系模式。
Based on the radioactivity of Kalium which generates 40 Ar in source rock through radioactive decay with geologic time passing by, the age accumulation effect of Argon isotope in natural gas pool is founded. 指出天然气藏中的氩同位素年代积累效应是建立在源岩中放射性钾随时间的放射性衰变产生40Ar的基础上;
On the basis of the component content of natural gas, carbon isotope ratios of methane and ethane, and isotope composition of rare gas, the geochemical characteristics of Ake-1 gas pool were studied in this paper. 根据天然气组分的含量、甲烷和乙烷碳同位素值及稀有气体同位素数据,分析了阿克1气藏天然气的地球化学特征。
