用量子场论方法计算了固液界面的吸附自由能，导出了油、水、石英叁相体系的润湿系数与温度的关系。计算表明，当系统的温度升高时，石英的亲水性增强，降低了多孔介质的残余油饱和度，这对热力采油机理研究有参考价值。
The influence of temperature on wetting properties of mineral surface is described by calculation of free energy of adhesion and the quantum field theory. The results show that the wetting coefficient increases, and the residual oil saturation decreases as temperature increases. The calculation is in agreement with the experimental results.
