Abstract: Rich carbazole compounds, including carbazole, alkylcarbazoles, benzocarbazoles and alkylbenzocarbazoles, were detected by GC/MS in lacustrine oils from Beisantai area, Junggar Basin. Changes in contents of carbazoles and its isomers indicate that there exists an obvious migration fractionation. From Fukang depression to Beisanta uplift, the concentrations of carbazole compounds and its benzocarbazoles have decreased during oil migration, but the relative contents of carbazole, methylcarbazoles and isomers with shield effects have increased. The results indicate that the distributions of carbazole compounds in oils of the same origin are mainly controllted by the oil migration, and they have potential significance in reseaching oil migration.
