The origin and accumulation mechanism of the marine oils in the Tarim Basin has long been a disputed issue. Compound specific isotope, fluid inclusion technique and age-indicating biomarkers have been used in investigating hydrocarbons generation and migration in this study. It is observed that most of the oils in the Tazhong and Lunnan uplifts correspond well with the Middle-Upper Ordovician source rocks according to biomarkers, suggesting their good genetic relationship.  The opinion of intensive oil mixing in the Tarim Basin suggests great deep petroleum potential in the basin, and unraveling hydrocarbons-accumulation mechanism is significant for further petroleum exploration.
