Abstract

Based on the analysis of the components and carbon and hydrogen isotopes of gases from the Triassic Xujiahe and other formations in the Sichuan Basin,the gas origin,gas source and significance of hydrogen isotopes are studied by combining previous research results and regional geological background. The results show that gas from the Triassic Xujiahe Formation in the Sichuan Basin is mainly hydrocarbon gas. The content of methane is 67.89%-98.05%,and the content of heavy hydrocarbon (C₂+) is 0.42%-16.62%. The content of non-hydrocarbon gas (CO₂,N₂) is low. Except the relatively high content of N₂ and CO₂ in the Well Yue121,the average content of N₂ is 0.82% and the average value of CO₂ is 0.26%. Gas from the Xujiahe Formation in Yuanba has average dryness coefficient as high as 0.991,which indicates the gas belongs to dry gas. While,gases from the Xujiahe Formation in other areas in the Central Sichuan Basin have dryness coefficient less than 0.95,indicative of wet gas. The δ¹³C₁value varies from -43.8‰ to -29.2‰,δ¹³C₂ value ranges from -33.5‰ to -20.7‰,δ¹³C₃ value is from -33.6‰ to -19.3‰ and δ¹³C₄value is from -27.2‰ to -22.2‰. The δD₁value is from -191‰ to -148‰,δD 2value is from -165‰ to -115‰ and δD₃ value is from -153‰ to -107‰. Methane and its homologues (C_2-4) become more enriched in ¹³C and D with increasing carbon number (δ¹³C₁<δ¹³C₂<δ¹³C₃<δ¹³C₄,δD₁<δD₂<δD₃),which are consistent with the carbon and hydrogen isotopic characteristics of thermogenic gases. The thermal maturity R_Oof natural gas from Xujiahe Formation in Yuanba is 1.09%-1.78%,and the R_O of the natural gas from Xujiahe Formation in other areas of Central Sichuan Basin is 0.64%-0.92%. Natural gas from the Xujiahe Formation in the central Sichuan Basin is mainly from the coal measure source rocks of the Xujiahe Formation. Natural gas from the 2^nd member of Xujiahe Formation in Yuanba is mixed gas,a mixture of the high-mature coal-derived gas from the coal measure source rock of Xujiahe Formation and the Lower Cambrian (Lower Silurian) oil-cracked gas. The δD of methane from the Xujiahe Formation in the Sichuan Basin is relatively high,higher than -200‰. Compared to the coal-derived gas from the source rocks formed in limnetic facies with freshwater in the Taibei Sag,Turpan-Hami Basin,though at similar thermal maturity,the difference of the δD of methane can be as high as 90‰,indicating that the source rock of Xujiahe Formation is formed in an environment with water salinization.
