Cementing material composition, cement slurry and preparation method and application thereof
The invention belongs to the technical field of well cementation cement, and particularly relates to a cementing material composition, cement slurry and a preparation method and application thereof. The cementing material composition provided by the invention comprises cement, phosphate, an early strength agent and a shrinkage reducing agent. Cement slurry prepared from the cementing material composition has the advantages of early strength, crack resistance and CO2 corrosion resistance, especially has supercritical CO2 corrosion resistance, and can ensure long-term storage of CO2.
本发明属于固井水泥技术领域，具体涉及一种胶凝材料组合物、水泥浆料及其制备方法和应用。本发明提供的胶凝材料组合物，包括：水泥、磷酸盐、早强剂和减缩剂。采用本发明的胶凝材料组合物制备的水泥浆料具有早强、抗裂、耐CO2腐蚀的优点，尤其是具有耐超临界CO2腐蚀能力，可以保证对CO2的长期封存能力。
