Popis:	Sulfate reducting bacteria (SRB) is isolated from practical oilfield produced water and added to the oilfield produced simulating water to investigate the corrosion component of SRB on N80 steel. Oilfield produced simulating water was prepared to four mediums in order to research SRB corrosion component. Weight loss results showed that the corrosion rate component contributed by SRB was 0.0093 mm/a, which accounts for 7.93% of the total corrosion rate of oilfield produced simulating water. Polarization results indicated that the SRB corrosion mainly increased cathode reaction rate and produced cathode depolarization. And the surface of N80 steel in four mediums all present pitting corrosion.
