Solid-phase suspension stabilizer for cement paste as well as preparation method and application of solid-phase suspension stabilizer
The invention provides a solid-phase suspension stabilizer for cement paste as well as a preparation method and application of the solid-phase suspension stabilizer. The invention relates to a preparation method of a solid-phase suspension stabilizer for cement paste. The cement paste solid-phase suspension stabilizer is obtained by carrying out polymerization reaction on a reaction system comprising 15 to 20 parts by weight of 2-acrylamido-2-methylpropanesulfonic acid, 10 to 30 parts by weight of an acrylic acid compound, 55 to 60 parts by weight of unsaturated sulfonate, 1 to 5 parts by weight of mercaptan and 200 to 500 parts by weight of water. According to the preparation method, the raw materials are specifically selected, so that the solid-phase suspension stabilizer capable of improving the stability of the cement paste in the well cementation operation of the ultra-high-temperature and ultra-deep well complex stratum can be obtained.
本发明提供一种水泥浆固相悬浮稳定剂及其制备方法、应用。本发明的水泥浆固相悬浮稳定剂的制备方法，通过使包括15‑20重量份2‑丙烯酰胺基‑2‑甲基丙磺酸、10‑30重量份的丙烯酸类化合物、55‑60重量份的不饱和磺酸盐、1‑5重量份的硫醇以及200‑500重量份的水的反应体系发生聚合反应得到所述水泥浆固相悬浮稳定剂。该制备方法通过对原料进行特定的选择，能够得到在超高温、超深井复杂地层固井作业中改善水泥浆稳定性的固相悬浮稳定剂。
