摘　　要：采用微观渗流模拟实验、岩心驱替实验、CT成像分析等方法 ,对中原油田马寨地区离子调节法处理污水进行了注入地层渗流模拟实验研究。结果表明 :在室温与地层温度 (75℃ )下处理水不沉淀结垢 ,对渗透率没有明显影响。For several years the produced water at Mazhai Oil Fields, Zhongyuan, has been treated by using an ions adjusting technology and the treated water of higher pH value has been used for reservoir flooding. Thus problem of scaling might occur. In this work the existance of scale in cores and the changes in core permeability are studied through flow experiments on micromodel and reservoir and artificial cores and CT imaging technique. It is concluded from the experimental results that the ions adjucted water does not tend to scaling and reduce core permeability notable.
