摘　　要：通过空气与原油在油藏温度和一定压力下低温氧化过程的模拟实验,对反应前后气体与原油的组成进行分析.结果表明,实验条件下低温氧化反应后原油芳烃含量减少,胶质含量增加,饱和烃含量和沥青含量基本不变,正构烷烃轻重组分比增加;原油黏度有所增加.Simulation experiment temperature oxidization（LTO） at was carried out on composition changes of air and crude oil in lowreservoir temperature and reservoir pressure. The results demonstrated that after oxidation, the aromatics content was decreased, the resins content was increased, the saturates content and the asphahents content were unchanged, the ratio of light composition to heavy composition in the aikane was increased, and the viscosity of crude oil was increased.
