Abstract

The effect of the thiourea base imidazoline quaternary ammonium salt corrosion inhibitor on the corrosion performance of X80 pipeline steel in three simulated oil-field waters with different pH was assessed by means of polarization curve measurement, electrochemical impedance spectroscopy (EIS) and scanning vibrating electrode technique (SVET) as well as characterization of corrosion morphology and corrosion products. Polarization curve measurement showed that the corrosion current density was the lowest in the water of pH7.2, followed by pH10.5, while the corrosion current density was the highest in the water of pH3.5，and as the temperature increased, the corrosion current density also increased. The EIS results showed that the diameter of capacitive reactance arc was the largest in the water of pH7.2, accordingly, the R_ct in the fitting result was significantly higher than those in the other two waters. The SVET analysis revealed that the adsorption film formation on the surface of pipeline steel in the water of pH7.2 was better than in the other two waters, while the ion current density decreased with time, indicating that the corrosion inhibitor molecule is more suitable for the case in the water of pH7.2. The film formation by adsorption reduces the ion current density, thereby effectively reduces the corrosion reaction rate. In conclusion, the corrosion inhibitor is much suitable for use in neutral waters and it has good corrosion inhibition effect in the temperature range of 40~60 ℃.
