摘要: Abstract Natural gases from the Qiudong and Hongtai gas fields in Taibei sag Turpan-Hami Basin of China were analyzed for stable hydrogen carbon isotopic characteristics, to investigate origin gas-source correlation. two are dominated by alkane with methane content varying 81.61% 92.57%. Dryness ranges 0.76 0.93, indicating an abundance wet gas. The compositions vary − 39.8‰ − 42.6‰ − 263‰ − 279‰ field, respectively, − 37.7‰ − 39.0‰ − 250‰ − 257‰ respectively. All have a characteristic distribution pattern among C1–C5 alkanes, which δ13CCH4
