The exothermic oxidation reaction between the oil and oxygen is emerged, the oxygen is consumed and carbon oxide is produced, and the heat can make the reservoir temperature increase and make the light component evaporate.
空气注入油藏后,氧气和原油发生放热氧化反应,消耗氧气生成碳的氧化物,而且反应产生的热量还会使油层温度升高,促使轻质组分蒸发。

油藏初始温度对火烧油层驱油效果影响较大，而油藏初始压力则影响较小。
The influence of initial temperature of reservoir is fairly important, and the initial pressure of reservoir is little important.
地层温度、压力皆南高北低，超压主要发育于南部葡萄花以下油层。
Formation temperature and pressure is all high in south and low in north. And overpressure mainly develops in the south below Putouhua oil layer.
实验结果表明，温度下降、原油组分改变、流速变化均能促进有机垢的形成，导致油层渗透率显著下降。
The result shows that these parameters' changes are the main factors that cause the reservoir permeability to drop obviously.
