摘　　要：本文综述了泡沫驱油过程中原油对泡沫稳定性的影响。运用热力学方法分析了原油与泡沫相互作用的强弱，将原油存在下泡沫的稳定性与液膜数相关联。微观模型观察结果表明，原油对泡沫稳定性影响的程度与原油性质有关，一般来说泡沫在轻质原油存在下的稳定性小于在重质原油存在下的稳定性。This paper presents a recent review on the destabilization of foams by crude oil in relation to improved oil recoveries. The topics involved are: ① foams and foam stability; ② interaction between crude oil and foam; ③effects of crude oil on foam stability. Two thermodynamic criteria, spreading coefficient S and entrance coefficient E, were suggested in 40s for crude oil/foam interactions in equillibrium. Recently a new determinable criterium, lamella number L, is suggested and lg L is shown to vary linearly with varying f b, the frequence of foam lamella breakdown, in a large amount of experiments. The stability of foam is more enfluenced by light crude oil.
