Preliminary Study on Corrosion Behaviour of Carbon Steel in Oil-Water Two-Phase Fluids

The corrosion behavior of type 1045 (AISI) carbon steel (CS) in oil-water fluids was investigated by considering the surface wetting state as the breakthrough point. The surface water wetting percentage (SWWP) and corrosion weight loss of CS in different oil-water fluids were measured. The morphology and composition of the corrosion films were detected via scanning electron microscopy, electron-probe face-scanning technology and Fourier-transform infrared spectroscopy. The results indicated that the corrosion weight loss of CS in the oil-water fluids corresponded with SWWP and that the corrosion process was influenced by the participation of oil.
