Through analyzing the effect of temperature and nitrogen on crude oil viscosity the influences of different nitrogen injection volume and injection modes on steam displacement are contrasted , the mechanism of nitrogen - assisted steam stimulation is clarified , which includes : heat carrying capacity is raised , the saturation of remaining oil is reduced after nitrogen - assisted injection is made ; crude oil flow is enhanced because of nitrogen compression and dispersion and the change of oil flow shape ; water back - production rate is improved by expanding the steam sweep volume and compensating in - situ energy ; steam distillation effect is enhanced
通过分析温度、氮气对原油粘度的影响，对比不同注氮量、不同注入方式等对蒸汽驱油效果的影响，弄清了氮气辅助蒸汽增产的机理主要表现在：氮气辅助后增加携热能力，降低残余油饱和度，氮气的压缩膨胀作用分散和改变了原油流动形态，增强了原油流动性；扩大蒸汽的波及体积，补充地层能量，提高回采水率，强化蒸汽蒸馏效应。
