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。
The microscopic seepage simulation experiment, core flooding experiment and CT imaging analysis were used to simulate the seepage formation of ion-treated sewage in Mazhai area of Zhongyuan Oilfield. The results show that water does not precipitate and deposit at room temperature and formation temperature (75 ℃), and has no obvious effect on permeability.
