Corrosion and Protection of Oil Tubes Inwall in Tahe Oilfield

Tahe oilfield was exploited in 1998.The crude oil of Tahe oilfield has strong corrosion to oil tubes due to the existence of H2S,CO2 and high mineralization water.With the oilfield exploitation,the corrosion of oil tubes is intensified with the increase of water content in the crude oil.In this paper,the corrosion situation and characters of the Tahe oilfield were analyzed.The corrosion reason and factors were discussed,and the protection measures were put forward.
