摘要(Abstract)：

针对稠油在火驱过程中原油燃烧量大，火驱前缘推进不稳定的问题，选取金属氧化物（α-Fe_2O_3）开展稠油催化火驱实验。采用动力学实验管，测定动力学参数，计算反应阶段的活化能，通过一维燃烧管实验，分析α-Fe_2O_3对燃烧前缘推进和峰值温度的影响。结果表明：添加α-Fe_2O_3催化剂后，稠油火驱过程中氧气利用率从0.75增加至0.8，驱油效率从85.1%增至88.0%，燃烧前缘趋于均匀地向前推进，燃烧效果有所改善，火线温度普遍高于500℃，α-Fe_2O_3是一种适用于火烧油层开采稠油的催化剂，值得进一步研究完善及应用。
In view of problems of large heavy oil combustion volume and unstable front progress during in-situ combustion(ISC) process, metal oxide(α-Fe_2O_3) is selected in catalytic ISC experiment of heavy oil. Kinetic tube is used to determine kinetic parameters and calculate activation energy during reaction stage. 1D combustion tube experiment is performed to analyze the influence of α-Fe_2O_3 on combustion front progress and peak temperature. The results show that after addition of α-Fe_2O_3 catalyst, oxygen utilization rate during heavy oil ISC process increases from 0.75 to 0.8, and displacement efficiency increases from 85.1% to 88.0%. Combustion front tends to progress forward uniformly and combustion effect is improved, with combustion front temperature higher than 500 °C. α-Fe_2O_3 is a suitable catalyst for heavy oil ISC production, which is worth further study, improvement and application.
