Superhigh-temperature cement paste suspension stabilizer as well as preparation method and application thereof
The invention provides an ultrahigh-temperature cement paste suspension stabilizer as well as a preparation method and application thereof. The suspension stabilizer comprises a polymer prepared from a 2-acrylamido-2-methylpropanesulfonic acid monomer, a vinyl polycyclic monomer, an unsaturated acrylamide monomer, an unsaturated cationic monomer and an unsaturated surfactant monomer. The preparation method of the suspension stabilizer comprises the following step: carrying out polymerization reaction on a 2-acrylamido-2-methylpropanesulfonic acid monomer, a vinyl polycyclic monomer, an unsaturated acrylamide monomer, an unsaturated cationic monomer and an unsaturated surfactant monomer in the presence of an initiator and a solvent to obtain the ultrahigh-temperature cement paste suspension stabilizer. The invention also provides application of the ultrahigh-temperature cement slurry suspension stabilizer as an additive of a cement slurry system for well cementation of deep wells and ultra-deep wells. The ultrahigh-temperature cement slurry suspension stabilizer can control the sedimentation stability of a cement slurry system at 240 DEG C to be 0.03 g/cm < 3 > or below.
本发明提供了一种超高温水泥浆悬浮稳定剂及其制备方法和应用。该悬浮稳定剂包括2‑丙烯酰胺基‑2‑甲基丙磺酸单体、乙烯基多元环单体、不饱和丙烯酰胺类单体、不饱和阳离子单体和不饱和表面活性剂单体制备的聚合物。该悬浮稳定剂的制备方法包括：使2‑丙烯酰胺基‑2‑甲基丙磺酸单体、乙烯基多元环单体、不饱和丙烯酰胺类单体、不饱和阳离子单体和不饱和表面活性剂单体在引发剂和溶剂存在下进行聚合反应，得到超高温水泥浆悬浮稳定剂。本发明还提供了该超高温水泥浆悬浮稳定剂作为深井、超深井固井用水泥浆体系的添加剂的应用。该超高温水泥浆悬浮稳定剂能够使240℃下水泥浆体系的沉降稳定性控制在0.03g/cm3以下。
