摘要：
The effect of flow velocity on the corrosion behavior of X100 steel in CO2-saturated produced water (CO2-SPW) was studied. Potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS) were used to study the corrosion behavior of X100 steel. X-ray diffraction (XRD), a metallurgical microscope, and a scanning electron microscope (SEM) were used to analyze corrosion product composition and morphology, respectively. The results show that the corrosion current density increases and impedance value decreases with the increase of the flow rate. The corrosion products are mainly FeCO3 and Fe3C. The corrosion degree of the bend segment is more serious than that of the straight segment. COMSOL simulation proposed the correlation between X100 corrosion behavior and material concentration and flow field distribution. A corrosion model was proposed, where the corrosion mechanism of X100 under simulated working condition was explained.
