In this paper, the origin of immature oil, biodegradation of crude oil, sources and episodes of oil charging have been investigated to reveal the origin and accumulation processes of heavy oils in the Qingdong Sag of Jiyang Depression, Bohai Bay Basin. Some indicators with highly resistant to biodegradation together with stable carbon isotopic compositions were used for oil-source correlation. Furthermore, the main factors controlling formation and distribution of heavy oils in the study area are discussed.
