Abstract: Carbon dioxide capture and storage is the primary way to reduce greenhouse gas emissions on a large scale. Carbon dioxide storage is the critical link of this technology, and the way in which to achieve long-term storage is a problem to be considered. The elastic and anti-corrosion cement slurry is the key for the successful storage of carbon dioxide. In order to develop the cement slurry for carbon dioxide storage, the influence of resin with both elastic and anti-corrosion properties on the performance of a cement slurry was investigated. The dispersant, retarder, and filtrate reducer suitable for the cement slurry were studied, and the performance of the designed cement slurry for carbon dioxide storage was evaluated. The experimental results show that the resin can reduce water loss and improve the elasticity and corrosion resistance of cement paste. The elastic modulus and corrosion depth of the resin cement slurry were significantly lower than those of the non-resin cement slurry. By studying the dispersant and retarder, the performances of the cement slurry for carbon dioxide storage was found to be able to meet the requirements of the cementing operation. The water loss of the designed cement slurry was low, the thickening time was more than three hours, and the rheological property was excellent. The elastic modulus and corrosion depth of the designed cement slurry was very low. The cement paste had a strong resistance to damage and corrosion. The structure after corrosion was denser than the conventional cement slurry, and the characteristic peak of corrosion products was weaker. The designed elastic and anti-corrosion cement slurry was well suitable for the cementing operation of carbon dioxide storage wells.
