| Abstract: |
| Through the methods of macroscopic detection, mechanical performance test and corrosion products analysis etc, the reasons of failure pipeline within some platforms in Weiyuan shale gas field were studied. The results show that the main factors causing corrosion are sulfate-reducing bacteria existing in water, carbon dioxide and chloride ions. |
| Key words: shale gas surface pipeline corrosion |
