摘　　要：在模拟地下油藏条件下,加入催化剂进行重质原油低温氧化反应实验研究,对氧化前后的气体组成及含量变化、原油组分变化进行分析.结果表明,加入催化剂后在150℃以下显著提高了原油低温氧化效率,且与未加入催化剂的低温氧化反应对比,加入催化剂后氧气消耗更多,生成二氧化碳含量增加.200℃以下原油重质组分含量下降,饱和烃、芳香烃轻质组分含量增加.The crude oil combined with catalysts was used to simulate low -temperature oxi‐dation（LTO） under the simulative oil reservoir condition ,and the effect of the catalysts on LTO was studied .The gas and oil composition after the reaction were analyzed .The results show that the efficiency of the L T O reaction has been significantly increased below 150 ℃ , and the more oxygen consumed ,the more carbon dioxide generated compared with the condi‐tion without catalysts .The heavy compositions of the crude oil were reduced and the light compositions with saturated hydrocarbons and aromatic hydrocarbon included were increased below 200 ℃ .
