Considering the extra-heavy crude oil SAGD produced water with high temperature,high pressure and high oil content in Liaohe oilfield,a water purifying agent,which is suitable for treating extra heavy crude oil produced water,is synthesized with polyhydric alcohol,epichlorohydrin and dimethylamine solution. The structure and thermal stability of the product were analyzed through the testing methods of IR,DTA. The ability of removing oil of the product is studied under various conditions using special temperature-tolerant and pressure-tolerant equipment designed by the authors. The results show that both the oil removal efficiency and oil removal speed is satisfactory considerably. Under the conditions of temperature 180 ℃,sedimentation time 30 min and dosage 300 mg/L,the final oil content is reduced from 70 053 mg/L to 453 mg/L,the oil remove rate could reach 99％.
