摘要：
Focusing on the air injection development mechanism of light and heavy oil reservoirs, typical light and heavy oil samples were selected for thermogravimetric experiments, and the thermal behavior and kinetics characteristics of crude oil at three oxidation stages were comparatively analyzed by the conversion method of Ozawa- Fynn-Wall, and the effect of surface effect on the oxidation reaction of light and heavy crude oil was also discussed. The results showed that: ①There is a transition zone between each oxidation stage, and the accurate selection of conversion rate is very important for kinetic parameters. ②The oxidation characteristics of light and heavy crude oil at different oxidation stages are obviously different. Light crude oil is mainly oxidized at low temperature, while fuel deposition and high temperature oxidation are not significant. Moreover, the initial temperature of low temperature oxidation, fuel deposition and high temperature oxidation stage of light oil is lower, which is more likely to induce oxidation reaction. Fuel deposition and high temperature oxidation of heavy oil are significant, and the oxidation reaction rate is faster. ③The surface area effect causes the low temperature oxidation activation energy of light oil to decrease by more than 15%, and the peak temperature decreases by 7-17℃. The deposition and high temperature oxidation of heavy oil fuels are significantly enhanced, and the burn-out temperature drops by 10-17℃. © 2021, Editorial Board of CIESC Journal.
