    Abstract
  • There are over ten gas producing beds and six main gas-generating rock intervals in the Sichuan Basin in the middle of China. In this paper, carbon isotopic data of natural gas from different regions and reservoirs were studied. The δ13C value of most gas samples show the pattern of δ13C1<δ13C2<δ13C3<δ13C4, indicating their biogenic origin. Samples with δ13C1>δ13C2 might be a mixture of gases from different source rocks or of different maturity. The δ13C value of humic gas is more negative than that of sapropelic gas. The δ13C value of the analyzed CO2 indicates it is of biogenic origin.
