Progress research on deviating wearing - corrosion between the sucker-rod and oil tube

This paper discusses the mechanism, as well as influencing factors, prevention - cure measures of deviating wearing - corrosion between sucker - rod and tube in pumping system. In view of the progressive results from other oilfields in our country, better effectiveness has been found when adding the corrosion inhibition into oil wells or using the coating materials with strong wearing quality.
