摘要
构建了天然气-水-活性剂混合体系与α-石英晶面构成的界面超分子结构模型,采用分子动力学方法研究了温度为350 K和325 K,活性剂为甲醇的情况下,岩石对天然气分子以及水分子的界面吸附行为的影响。研究发现甲醇分子可降低水分子与α-石英表面的结合能从而起到降低水锁的危害,并从分子动力学的角度解释了解除水锁危害的微观机理。
Gas-water-surfactant mixed system and alpha quartz crystal interface supramolecular structures model was constructed. Using the method of molecular dynamics, the adsorption behavior of quartz crystal-water and quartz crystal-gas under the temperature of 350 K and 325 K were studied with methanol as the surfactant. The result showed that methanol molecules in a certain extent remove water-blocking harm through reducing water molecules and alpha quartz surface binding-energy. The microscopic mechanism of removing water-blocking hazard from molecular dynamics was explained.
