The results show that the predominating reason is bacteria corrosion and scale corrosion induced by sulfate reducing bacteria(SRB), secondly electrochemical corrosion of dissolved oxygen, carbon dioxide and high salinity formation liquid, furthermore paraffin deposition of oil well in.

The corrosion factors are soil corrosion,bacteria corrosion and the constru.
