用量子場(chǎng)論方法計(jì)算了固液界面的吸附自由能，導(dǎo)出了油、水、石英三相體系的潤(rùn)濕系數(shù)與溫度的關(guān)系。計(jì)算表明，當(dāng)系統(tǒng)的溫度升高時(shí)，石英的親水性增強(qiáng)，降低了多孔介質(zhì)的殘余油飽和度，這對(duì)熱力采油機(jī)理研究有參考價(jià)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.
