Abstract:The ignition process has a significant influence on the success of in-situ combustion at heavy oil reservoirs. During this process, oxidation reactions between crude oil and injected air mainly occurred. In this paper, a series of oxidation experiments were performed at different reaction temperatures and air-oil ratios to investigate the heavy oil oxidation characteristics at different stages of the ignition process. The results revealed that heat release and production of CO and CO
