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.
