针对部分稠油油藏火驱过程中低温氧化诱导期长和燃烧效率低问题，设计开发了一套多孔介质热效应监测装置，系统评价了催化剂种类、催化剂质量分数、复配催化剂和环境温度对稠油燃烧的影响。结果表明，该热效应监测装置能够高效快速地评价催化剂对原油燃烧表现的影响，从而筛选出合适的催化剂体系。复配体系[环烷酸钴（0.5% Co）+环烷酸锰（0.5% Mn）]能够将新疆油田A油藏稠油的燃烧起始温度降低60℃，在催化该稠油燃烧具有良好的应用前景。环境温度的升高能够明显促进燃烧的发生，但环境温度对燃烧强度的影响有限。

To solve the problems of long low-temperature oxidation induction period and low combustion efficiency during insitu combustion of some heavy oil reservoirs, a set of porous medium thermo-effect cell (PMTEC) was designed and developed, and the effects catalyst type, mass percentage of catalyst, mixed catalyst, and environment temperature on heavy oil combustion were systematically evaluated using this cell. The results indicated that PMTEC could efficiently and quickly evaluate the influence of the catalyst on the combustion performance of crude oil, so as to screen out a suitable catalyst system. The mixed system [cobalt naphthenate (0.5% Co) + manganese naphthenate (0.5% Mn)] could reduce the initial temperature of combustion of heavy oil in A reservoir of Xinjiang Oilfield by 60 ℃, which meant that this catalyst system had good application prospects in catalyzing heavy oil combustion. The increase in environment temperature could significantly promote the occurrence of combustion. However, the influence of environment temperature on combustion intensity was limited.
