Self-healing mechanism of deposited carbonates in cement cracks under CO2 storage well conditions
In CO2 geological storage wells, the leakage of CO2 along the micro-cracks of the cement sheath of abandoned wells is one of the main risks of CO2 leakage. The chemical reaction between CO2 and oil well cement can realize self-healing of micro-cracks in the cement sheath. In this study, self-healing...
