  2. 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

    通過分析溫度、氮氣對原油粘度的影響，對比不同注氮量、不同注入方式等對蒸汽驅油效果的影響，弄清了氮氣輔助蒸汽增產的機理主要表現在：氮氣輔助后增加攜熱能力，降低殘余油飽和度，氮氣的壓縮膨脹作用分散和改變了原油流動形態，增強了原油流動性；擴大蒸汽的波及體積，補充地層能量，提高回採水率，強化蒸汽蒸餾效應。
