用聚合物驱采出水在不同渗透率天然岩心上进行注水实验，结果表明，采用常规污水处理方法处理后的聚合物采出水，当悬浮固体含量１５ｍｇ／Ｌ左右、含油量１５ｍｇ／Ｌ、悬浮颗粒直径小于５μｍ的悬浮固体颗粒体积占悬浮颗粒体积的百分数大于７０％时，完全可满足中、高渗透层注入水水质指标的要求。为降低水处理工艺的成本，提高经济效益，对于高渗透层还可将悬浮固体含量、油含量的水质指标进一步放宽为３０ｍｇ／Ｌ。
Water flooding experiments on natural cores with different permeability by polymer flooding showed that when the suspended solids content was about 15mg / L, the oil content was 15mg / L, the suspended particles When the volume of suspended solid particles less than 5μm in diameter accounts for more than 70% of the suspended particle volume, it can fully meet the requirements of water quality index of medium and high permeable layer. In order to reduce the cost of water treatment process and increase economic benefits, the water quality index of suspended solids content and oil content can be further relaxed to 30 mg / L for the high permeability layer.
