%X A failed oil tube used in natural gas well was examined by optical microscope,scanning electron microscope ,X-ray diffractometer and X-ray spectrometer.Corrosion behavior of 35CrMo steel samples of the oil tube was also investigated by means of salt spray tests in laboratory.The results show that CO_2 and H_2O are primary factors in the corrosion of oil tube.The corrosion product is FeCO_3,non-metallic inclusions in the steel and erosion of natural gas fluid played an important role in accelerating the corrosion.
