Gas tubes of Xujiahe gas reservoir in West Sichuan have serious corrosion problems, which cause a great loss. This paper studied the corrosion mechanism of gas well through indoor and field simulation test and made an analysis by CorrosionAnalyzer software. It＇ s found the corrosion was mainly caused by CO2 and the tube with 13Cr could be used to prevent corrosion in Xujiahe gas reservoir.
