摘要
The mathematical models of biodegraded mixed-source oils’ biomarkers change along with the mixed proportion and the calculation method for the contribution rate of oil sources were established by mathematical demonstration and artificial oil-mixing experiment, and in addition, the effect of biodegradation on the mixed proportion is illustrated. However, the situation will appear more complicated if use normal crude oils rather than biodegraded end-member oils in varying degrees, the contribution rate of crude oils of the high biomarkers ratio will be overestimated or underestimated.
