The primary function of cement ring is to support and hang the casing, seal formation fluids and prevent interlayer channeling. However, in highacid oil and gas fields, the cement ring is susceptible to corrosion by acidic media such as CO 2 and H 2 S, which seriously shortens the production life of oil and gas wells and causes substantial economic losses.
