英文摘要: Abstract(#br)Anyue gas field is a large gas field located in the central Sichuan Basin, China. Although many studies have been carried out previously, the formation mechanism of this field is unclear and currently under debate. To better understand the accumulation history, the role that groundwater plays in transporting hydrocarbons within sedimentary basins and water-gas interactions, stable and noble gas isotopes were measured in thirteen free gas samples from the Anyue gas field. In addition, nine formation water samples and five reservoir bitumen samples were analyzed for stable carbon isotopes. δ 13 C(CH 4 ) values in the gas samples range from −35.0 to −32.6‰, showing evidence of thermogenic origin. δ 13 C values among three different types of samples (free gases, water-dissolved...
