摘要：

The N80 steel corrosion behavior of the produced water in Huabei oil field on behalf of NaCl/ NaHCO3 solution were studied by the corrosion weight loss method, and the fitted chart board involved salinity and anion content was built based on the least squares principle. Results show that influenced by Cl- and HCO3- control the corrosion curve involves three parts: passivating area, activated area and high corrosion area. The corrosion behavior shows that the area when Cl-% content in 16.7 similar to 37.5% was HCO3- passivating control; in 37.05 similar to 90.9% was HCO3- and Cl- coordinated control; in 90.9 similar to 100% belong to Cl- perforation control. The fitted chart board considered water salinity and anion content could determine whether the corrosion occur or not, thus may provide theoretical foundation and guidance for the next support design of anticorrosion measures with carbon steel.
