Effect of CO2 solution on Portland cement paste under flowing, migration, and static conditions

In this study, a dynamic corrosion device for cement paste was developed according to the underground conditions of oil and natural gas wells, which possess a largely dynamic and constantly migrating corrosive medium. Using CO2 as the corrosion medium, the effects of the three corrosion conditions, namely static non-migration, dynamic non-migration, and dynamic migration of the corrosion solution, on the corrosion process of cement paste were...
