  • The maturity of lacustrine oils in Huqing oilfield is low, and the role of biodegradation is poor. Rich carbazole compounds, including carbazole, alkylcarbazole and benzocarbazoles were detected by GC/MS in lacustrine oils from Huqing oilfield. The results indicate the maturity plays an important role on the concentration of carbazole compounds and its relative contents, and the biodegradation plays weak role on the carbazole compounds. The concentration of carbazole compounds, the ratio of alkylcarbazole/benzocarbazole and the benzocarbazole ratio are not suitable to be the indicator of the oil migration, which are mainly controlled〖KG*2〗by the maturity of lacustrine oils, and the isomer ratio of dimethycarbazole is still a good parameter of the oil migration.

Abstract: The maturity of lacustrine oils in Huqing oilfield is low, and the role of biodegradation is poor. Rich carbazole compounds, including carbazole, alkylcarbazole and benzocarbazoles were detected by GC/MS in lacustrine oils from Huqing oilfield. The results indicate the maturity plays an important role on the concentration of carbazole compounds and its relative contents, and the biodegradation plays weak role on the carbazole compounds. The concentration of carbazole compounds, the ratio of alkylcarbazole/benzocarbazole and the benzocarbazole ratio are not suitable to be the indicator of the oil migration, which are mainly controlled〖KG*2〗by the maturity of lacustrine oils, and the isomer ratio of dimethycarbazole is still a good parameter of the oil migration.
