摘要：

主要根据气体组分和同位素资料,本文讨论了三水盆地烃气和CO2、N2、He等非烃气的成因.CO2主要来自地球深处,N2由生物化学作用生成,He为放射性元素蜕变产物,烃气有生化烃与热解烃两类.

Abstract:

Based on chemical composition and stable carbon isotope data, this pa-per discusses the origin of CO2N2,He and gaseous hydrocarbon in SanShuiBasin, Guangdong Province. The CO2 mainly comes from deep-earth,N2 is the product of biochemical process and He is the product of the decay of radio-element. Gaseous hydrocarbon includes biochemical methane and thermodegr-adation hydrocarbon gas.
