摘要

Failed oil tubes and the associated corrosion products from gas wells in the Zhongyuan oil field in China were studied by X-ray diffraction, X-ray photoelectron spectroscopy, and electron probe microanalysis. Results showed that CO2 and condensate were primary factors in the corrosion of the tubes. However, non-metallic inclusions in the steel played an important role in accelerating both localised corrosion and cracking in the CO2 containing environment. The possibility of using inhibitors in the gas wells to prevent this sweet gas corrosion was also investigated by means of corrosion tests in the laboratory.
