Cementing material additive composition, cement slurry and application of cementing material additive composition and cement slurry
The invention provides a cementitious material additive composition, cement slurry and application of the cementitious material additive composition and the cement slurry. The admixture composition comprises retarders, a fluid loss agent and latex, the retarders comprise a first retarder and a second retarder, the first retarder comprises hydroxycarboxylic acid and/or hydroxycarboxylate, and the second retarder comprises an unsaturated sulfonic acid monomer and a copolymer of an unsaturated carboxylic acid monomer and a cationic monomer. The admixture composition provided by the invention can ensure that the aluminate cement slurry does not crack under a hydrothermal condition while enabling the thickening time and slurry water loss of the aluminate cement slurry to meet working requirements, and can be used for oil well cementation and carbon sequestration well cementation.
本发明提供一种胶凝材料外加剂组合物、水泥浆料及其应用。本发明的外加剂组合物包括缓凝剂、降失水剂和胶乳，其中所述缓凝剂包括第一缓凝剂和第二缓凝剂，所述第一缓凝剂包括羟基羧酸和/或羟基羧酸盐，所述第二缓凝剂包括不饱和磺酸单体、不饱和羧酸单体与阳离子单体的共聚物。本发明的外加剂组合物可以使铝酸盐水泥浆料的稠化时间、浆体失水量符合工作要求的同时，保证其在水热条件下不开裂，可用于油井固井及碳封存固井。
