摘要
针对用普通硅酸盐水泥固井时早期强度低、水泥石收缩导致水泥环胶结不良及用氯化钙作为早强剂存在的一些缺点,研制了一种新型油井水泥早强剂SS—91。室内试验和现场应用表明,该早强剂能提高水泥石的早期强度,并随养护时间的延长,强度持续增长,配合其它外加剂使用,各种性能都合乎要求。
Based on the disadvantage of normal cement hardener , SS -91 oil well cement hardener was studied . It is indicated that SS -91 can increase the early strength of cement , and it is compatible with other cement additives .
