生物标志物的绝对浓度以凝析油最低，生物降解原油最高，正常原油介于两者之间。

For the concentration of biomarkers, the biodegraded oil is highest, the condensate is lowest, and the normal oil in between.

沥青质钌离子催化氧化技术对于强烈生物降解原油的油-油对比、油-源对比提供了一种新的途径。

Ruthenium-ions-catalyzed oxidation of the asphaltene provided a new pathway for the oil-oil correlation and oil-source correlation of heavily biodegraded oil.
