Abstract: 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.
