摘　　要：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_(2)O_(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_(2)O_(3)对燃烧前缘推进和峰值温度的影响。结果表明:添加α-Fe_(2)O_(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_(2)O_(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 com-bustion(ISC)process,metal oxide(α-Fe_(2)O_(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 ex-periment is performed to analyze the influence ofα-Fe_(2)O_(3) on combustion front progress and peak temperature.The re-sults show that after addition ofα-Fe_(2)O_(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_(2)O_(3) is a suitable catalyst for heavy oil ISC production,which is worth further study,improvement and application.
