摘要
岩石的润湿性是控制油藏中油（气）水分布的重要因素，影响润湿性的因素很多，主要研究了原油成分，注入水pH值对润湿性的影响，认为，在pH值低于12的情况下，岩石湿润性不胡PH值升高而改变，当PH值达到13时，亲油岩石亲油性减弱，亲水性增强，其变化程度与注入流体中碱的浓度以及原油中酸质成分有关。
Wettability of rock is an important factor that controls distribution of oil(gas) and water in reservoir.This paper resents laboratory results of effect of oil composition and injected water pH on wettability.When the pH is below 12,rock wettability will not change with increase of pH,and when the pH reaches 13,oil wetness will decrease and water wetness will increase in oil wet rocks,with these changes′ magnitude dependent on alkality of injected water and acid composition in oil.
