摘 要:针对轻、重质油油藏注空气开发机理,选取典型轻、重质油样进行热重实验,采用改进的Ozawa-Flynn-Wall等转化率法对比分析了不同性质原油三种氧化阶段的热行为和动力学特征,同时探讨了表面积效应对轻、重质原油氧化反应的影响。研究表明:①各氧化阶段之间存在过渡区域,转化率的准确选取对动力学参数至关重要。②轻、重质原油不同氧化阶段的氧化特征存在明显差异,轻质油以低温氧化为主,燃料沉积和高温氧化不显著,且低温氧化、燃料沉积、高温氧化阶段的起始温度更低,更易诱发氧化反应;重质油燃料沉积和高温氧化显著,氧化反应速度更快。③表面积效应导致轻质油低温氧化活化能降低15%以上,峰值温度降低7~17℃。重质油燃料沉积和高温氧化显著增强,燃尽温度下降10~17℃。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℃.
