Composition for preparing retarder and retarder
The invention relates to a composition for preparing a retarder and the retarder prepared from the composition. The composition for preparing the retarder provided by the invention comprises water, a stabilizer, itaconic acid, acrylic acid, 2-acrylamide-2-methylpropanesulfonic acid, a silane coupling agent, an alkaline substance and an initiator. The retarder provided by the invention has good temperature resistance, and can meet the requirement of 60-130 DEG C; in addition, the linear relation of the addition amount of the retarder is good, the strength of set cement is not influenced, and the retarder has good compatibility with other admixtures of oil well cement.
本发明涉及一种用于制备缓凝剂的组合物以及由其制备的缓凝剂。本发明提供的用于制备缓凝剂的组合物包括水、稳定剂、衣康酸、丙烯酸、2‑丙烯酰胺‑2‑甲基丙磺酸、硅烷偶联剂、碱性物质和引发剂。本发明提供的缓凝剂耐温能力好，能满足60‑130℃的要求；并且缓凝剂的加量线性关系好，不影响水泥石强度，和油井水泥其他外加剂相容性好。
