The cement sheath used in H2S-CO2 mixture gas storage and high-temperature and high-pressure (HTHP) production wells is easily corroded; thus the cement has strict requirements for corrosion-resistant properties. In this work, a new additive, HTHP-CRA, was used to improve corrosion-resistant propert...
