The compatibility of polymer-bearing produced water and corrosion inhibitor, bactericide has been explored from the angle of suspended solids content (ssc) of produced water from water treatment process of a station in Shengli Oilfield. The results show that cationic corrosion inhibitor and bactericide can interact with negatively charged suspended solids and polymers in produced water, resulting in the increase of ssc of produced water. Therefore, the use of cationic agents should be avoided for polymer-bearing produced water, therefore non-ionic and zwitterionic agents should be alternatives. Experiments show that the zwitterionic bactericide not only effectively controls SRB, but also hardly effect on the ssc of produced water.
