Conventional recoverable oil reserves have been greatly reduced in our country. Alternatively, heavy oil was nearly a large proportion of oil and gas resources, so it had become a hot spot of research how to exploit heavy oil and how to enhance heavy oil recovery recently. Industrial application shows that it is very difficult to significantly improve the recovery ratio of heavy oil using with any single heavy oil recovery technology. A new heavy oil recovery technology as well air-injection soft catalytic oxidation technology was presented in the paper while its feasibility was discussed in theory and techniques. The recovery technology compromises the merits of many methods of heavy oil recovery, such as thermal recovery, catalytic oxidation, oxicracking, hydrothermal cracking, flue gas flooding, surfactant water flooding etc, which is a high efficiency composite oil recovery technique. The catalytic oxidation operation condition for heavy oil was selected through experimental study. Finally, the change of O2 content in produced gas was measured and the mechanics of air-injection catalytic oxidization oil displacement were further confirmed through simulating the catalytic oxidation course below stratum. The results of experiment showed that the viscosity of Liaohe heavy oil was decreased from 382.6Pa·s to 0.023Pa·s , which nearly approaches viscosity of light oil, under the experimental conditions(mSp-1=0.2％, mR=1.4％, mH20=60％, 200℃, 0.5MPa and 36h). The content of N2, O2, CO2 and others hydrocarbons gas in produced gas was separately 95.37％, 1.63％, 1.53％ and 1.47％ after oxidating heavy oil for 5 days under the condition of simulated formation which the content of O2 was lowered from 21％ in air to 1.63％ in tail gas. Thus it can be seen that the catalytic oxidation effect for heavy oil is obvious.
