英文摘要：

The corrosion mechanism of pipelines induced by muti-phase flow under the condition of CO2 and H2S coexistence and the main factors influencing corrosion process are discussed. Present researches and developments on CO2/H2S induced corrosion are reviewed. The demands and principles for material selection under CO2/H2S coexistence conditions are presented. The emphases trend of researches on CO2/H2S corrosion and CO2/H2S-corrosion resisting pipeline steels are also prospected.
