摘　　要：在模拟地层条件下 ,通过室内实验 ,研究了油田所用调剖剂对岩石润湿性的影响 .结果表明 :注入调剖剂后 ,亲水岩石的亲水程度增强 ,而亲油和中性岩石的润湿性变为亲水或强亲水 ;岩石润湿性的变化与调剖剂质量浓度、矿化度、pH值有关 ;岩石润湿性的变化主要是调剖剂在岩石表面的吸附造成的 ,并且在岩石表面吸附的物质具有亲水性 。An experimental study was conducted about the effect of pro file control agent on reservoir rock wettability in modeling the conditions of s tratum. The results show: the degree of wetting water increase for the rock of w etting water and the wettability change into wetting water for the rock of wetti ng oil and middle wettability after injecting profile control agent; the altera tion of wettability is related to the concentration of profile control agent、mi neralization concentration and pH; the cause of variations of rock wettability i s absorption of profile control agent in the surface of rock, and the absorbed m aterials in the rock have the properties of wetting water, making the wettabilit y of rock change into wetting water or strongly wetting water.
