摘要 |
The present invention provides set retarding additives, set retarded hydraulic cement compositions and methods of using the set retarded cement compositions for cementing subterranean zones in wells. A preferred set retarding additive comprises an alkanolamine salt produced by the reaction of a hydroxy carboxy acid, such as tartaric acid, gluconic acid or glucoheptonic acid, with an alkanolamine, such as monoethanolamine, diethanolamine or triethanolamine.
