Abstract: Water flooding and process scheme in Cainan oil field, Zhunggar basin，Xinjiang were introduced. Based on the quality of produced water and the technical standards of re-injected water, the bacteria, oil content, suspension, sulfide, corrosion rate of produced water were investigated. The treatment reagents were tested and screened in the laboratory and the reagents of Sanda Company PAC, JM-300, the reagents of Keli company KL-0308, KL-0305 were used in field application. After treatment the produced water quality met the standards for re-injection.
