摘要
Based the previous research, this paper takes the Santai-Beisantai area of the Junggar Basin for an example, and analyzes the dependability of Ts/Tm. It is pointed out that Ts/Tm increases with maturity and is hard to be biodegraded, and can be used to distinguish the maturity of different type of crude oil. The bitumen and heavy oil derived from the result that the crude oil at low evolutionary stage suffered from loss and strong biode-gradation. The medium density oil comes from the result that oil at mature evolutionary stage suffered from loss and moderate biodegradation.
