| 英文摘要 | The Tarim, Qaidam, and Ordos basins, located in Northwest China, are recognized as three significant oil and gas reservoirs, and a comprehensive geochemical analysis of the crude oils sourced from these basins has been conducted to elucidate the various factors, that influence the concentrations and distribution patterns of carbazole compounds. The average concentration of carbazole compounds in fresh lacustrine facies crude oil is significantly higher compared to those from salt lake facies and marine facies. Furthermore, salinity exerts a significant influence on the alkylation of methylcarbazole, whereas its effect on dimethylcarbazole alkylation is comparatively less pronounced. Under the premise of fully correcting the migration distance, the sedimentary environment (salinity, redox conditions) plays a dominant role in the distribution of carbazole compounds. Sedimentary facies and depositional environments also affect the total nitrogen concentrations and maturityrelated parameters, such as the 1-MC/4-MC ratio. However, these factors minimal influence on migration indicators, such as the ratios of 3-MC/4-MC, 1,8-DMC/2,7-DMC, 1,3-DMC/2,7-DMC, and [a]/([a] + [c])-BC, which serve as reliable diagnostic tools for inferring the sedimentary environment. These findings indicate that carbazole compounds can serve as valuable tools for oil-source correlation studies. |
