A Study on the Corrosion and Scale Buildup of Produced-Water Reinjection Pipeline in Dawangzhuang Oilfield

In the light of the corrosion and scale deposit in the produced-water reinjection pipeline in Dawangzhuang oilfield, the operation condition of produced-water reinjection pipeline is analyzed. To solve this problem.a room experiment on synthetic.formula and field test to determine a corrosion inhibitor have been carried out. A corrosion inhibitor, called HZl2.is selected. The site test results indicate that this inhibitor has a good effect in corrosion resistance and scale deposit resistance to the produced-water reinjection pipeline.
