摘要
讨了原油极性组分（非烃、沥青质）的吸附机理及其吸附性、润湿性特征；介绍了ＮＳＯ极性化合物与润湿性的关系。极性化合物的吸附可能是多种机理共同作用的结果。吸附作用可导致储层润湿性反转，润湿性是决定原油采收率的主要因素。通过改变储层润湿性，可能有利于提高原油采收率。极性化合物的吸附等特性在储层润湿性研究、油田开发管理中具有重要意义。
The adsorption mechanisms of polar fractions(nonhydrocarbon,asphaltene) and their characteristics of adsorption and wettability are discussed and the relation between NSO polar compound and wettability is introduced.There are several possible mechanisms for polar fractions'adsorption.Adsorption may lead to the reversion of reservoir wettability.Wettability is the main factor for determing the recovery of crude oil.The recovery of crude oil may be enhanced by changing the wettability of reservoir.Therefore,the adsorption of polar fractions accounts for wettability change which has significant effects on oil recovery.The adsorption of polar fractions can't be excluded from improving reservoir management.
