摘　　要：对芳深 9、芳深 7、芳深 6井的天然气组成及甲烷同位素分析表明 ,松辽盆地北部昌德CO2 气为幔源无机气 ,该CO2 气是以由徐家围子连锁断层系下延与局部岩浆房相接作为通道 ,幔源热流底辟体中的CO2With the analysis of the constitution of natural gas and methane isotope of Fengshen 9, Fengshen 6 and Fengshen 7 wells,it indicates that the carbonate dioxide gas is mantle\|derived inorganic in Changde in the north of Songliao basin. Through the channel way of the connnection of the base of Xujiaweizi linked system of faults with partial chamber,the carbonate dioxide gas in the mantle\|derived heat flow diapris move up into appropriate volcanic rock encirclement along the faults, and form gas pool.
