| 摘 要： | 大庆兴城地区天然气组分和碳同位素具有“杂、干、重、反”4个基本特征，即天然气组分复杂多样，烃类气体中甲烷含量高，碳同位素重，烷烃碳同位素普遍出现反转序列.甲烷气体碳同位素重和烷烃碳同位素普遍出现反转序列是无机烃的特征，但并非其独有的特征.与烃类气体伴生的非烃类气体CO2、He的高含量与同位素分析表明具幔源成因特征，结合大庆兴城地区地质背景，认为不但非烃类气体具无机成因气，而且烃类气体中也有无机成因气的存在，反映出兴城地区天然气为有机成因与无机成因的混合气体.无机气体是岩浆与火山活动的产物.

| Abstract: | The natural gases in Xingcheng area of Daqing,Heilongjiang Province consist of hydrocarbon,CO2,N2,H2,He etc,among which the hydrocarbon,especially the CH4 is the dominating component.The carbon isotopes of the natural gases are commonly heavy and most of the hydrocarbon series are abnormal,which are characteristics of inorganic hydrocarbon gases.The chemical composition and isotopes of CO2 and He gases show that mantle-derived gases exist in the area.Together with the geological setting of Xingcheng area,it is considered that inorganic matter occurs in both non-hydrocarbon and hydrocarbon gases in the area,showing mixed natural gases of organic and inorganic origin.The inorganic gases are mainly caused by magmatism and volcanism. |
