摘要：

黄桥地区4口井的天然气以CO2为主,伴有烃气和氢、氦等气体。CO2的δ13C值为-5.88‰至-2.874‰,甲烷的δ13C值为-40.10‰至-37.643‰。气藏可能是多源混合气藏。

Abstract:

Natural gas is discovered in 4 wells in Huangqiao region, north Jiangsu.The gas is composed mainly of CO2 with small amount of hydrocarbon, helium and argen. The δ13C-values of CO2 range from -5.88 to -2.874‰, and that of methane ranges from -40.10 to -37.643‰. The pool may propably be mixed one of multisource.
