摘　　要：松辽盆地昌德气藏是目前世界上发现的唯一有充分地球化学依据,以产烷烃气为主的无机成因气藏。加强对昌德无机气藏的解剖,对于拓展我国天然气的勘探领域,具有重要意义。在昌德气藏上方,布置了一条贯穿芳深1井和芳深2井的地球化学剖面,通过研究不同地球化学指标在气藏上方的显示特征,确定了昌德气藏有效地球化学方法组合及异常识别标志。同时,结合甲烷碳同位素的分析,可以从一定程度上判断下伏气藏的无机成因属性。The Changde gas reservoir in the Songliao Basin is the only inorganic gas reservoir in the world which mainly produces alkane gas with a full geochemical complement. Therefore,the study of Changde inorganic gas reservoir has a great significance for the development of China＇s natural gas exploration. We designed a geochemical profile crossing wells Fangshen1 and Fangshen2 above the Changde gas reservoir,studied the near-surface display of different geochemical indicators,and selected effective geochemical methods and abnormal indicators. The analysis of methane carbon isotopes can help judge the inorganic origin of the reservoir.
