It shows good corrosion protection property to neutral or sour sewage in oilfields. When the concentration of corrosion inhibitor is 10～20 mg/L, the corrosion protection rate is about 90%, and the corrosion rate is less than 0.076 mm/a. Due to the low-priced raw materials and good corrosion protection property of the product, SF-103 corrosion inhibitor revealed a good application forecast.
