摘要: 根据原油的生物标志物和碳同位素等特征,论述了吐哈盆地台北凹陷西部弧形构造带混源原油存在的依据。按照物质平衡法原理,利用相混合两类原油(煤系油和湖相油)的αααRC27百分含量,建立了混源原油混合比例数学模型。利用混合原油的生物标志物参数和数学关系式,计算了西部弧形构造带两种原油的混合比例。对混合原油甾烷、萜烷谱图进行了数值模拟,与实际的混合原油的甾烷、萜烷谱图和参数进行了比较,得出了令人满意的结果。最后确定了该构造带各类原油的分布特征。

Abstract: The existence of mixed crude in western arc structural belt of Taibei Depression in Turpan-Hami Basin is explained,according to some characteristics of crude oil such as biomarkers and carbon isotope ratio.On the basis of the principle of material balance,a mathematical model for hybrid scale of mixed crude was established by the use of αααRC27 percentage of two kinds of crude oils including crude oil derived from coal measures and crude oil originated from limnic shale.The hybrid scale of mixed crude was calculated by using the mathematical model and the parameters of biomarkers of two kinds of crude oil.The spectrums of sterane and terpane were simulated and compared with some parameters and spectrums of actual mixed crude.A satisfactory result has been obtained.The distribution characteristics of different kinds of crude oil in this structural belt were determined.

Key words: Turpan-Hami Basin, arc structural belt, mixed crude, numerical modeling, crude oil distribution
