Anti-corrosion material for cement paste, carbon dioxide corrosion resistant cement paste and preparation method and application of carbon dioxide corrosion resistant cement paste
The invention relates to the technical field of oil and gas well cementing cement paste, and discloses an anti-corrosion material for cement paste, carbon dioxide corrosion resistant cement paste and a preparation method and application of the carbon dioxide corrosion resistant cement paste. The anti-corrosion material comprises a mixture A and a mixture B, wherein the mixture A comprises activated carbon, nano silicon dioxide and nano aluminum oxide; the mixture B comprises a component C and a component D; the component C is selected from diatomite and/or fly ash; the component D is selected from one or more of metakaolin, pumice and coal gangue. The anti-carbon dioxide corrosion cement paste prepared from the anti-corrosion material has good anti-corrosion capability in a CO2 corrosion environment, the compressive strength of set cement before corrosion is higher, the structure is compact, the compressive strength of the set cement after corrosion is not obviously reduced, the permeability is small, the mechanical property is good, the sedimentation stability is good, the rheological property is good, and the like. And the well cementation quality of the CCUS well is guaranteed, and efficient storage of CO2 is achieved.
本发明涉及油气井固井水泥浆技术领域，公开了用于水泥浆的防腐蚀材料、抗二氧化碳腐蚀水泥浆及其制备方法和应用。该防腐蚀材料包括混合物A和混合物B；其中，所述混合物A包括活性炭、纳米二氧化硅和纳米氧化铝；所述混合物B包括组分C和组分D；所述组分C选自硅藻土和/或粉煤灰；所述组分D选自偏高岭土、浮石和煤矸石中的一种或多种。采用该防腐蚀材料制成的抗二氧化碳腐蚀水泥浆在CO2腐蚀环境下具有良好的防腐蚀能力，腐蚀前水泥石抗压强度较高、结构致密，腐蚀后水泥石抗压强度无明显衰退、渗透率小、力学性能良好、沉降稳定性好、流变性好等综合性能，保障CCUS井固井质量，实现CO2高效封存。
