Application of Rare Earth Titanium Nano Coating Pipe to Changqing Oilfield

The suitability of rare earth titanium nano coating pipe used in severely corroded blocks in Changqing area was investigated through field test. And the effect of rare earth titanium nano coating pipe in high temperature environment was investigated through heating test in laboratory. These tests were carried out to solve the problems of pipe corrosion (including threaded corrosion), partial wear, dirt plugging, sucker rod corrosion, partial wear off and others occurring in oil production. The test results show that the service life of pipe extended by 2-3 times after being coated with rare earth titanium nano coating, and the economic costs could be significantly saved.
