CE65S is a kind of set cement lattice expanding agent. It is used in oil well cement to prevent slight shrinkage of set cement, reduce permeability, cement off channeling path, slightly expand to increase interfacial cementation ability, and is slightly thixotropic to reduce free water. It can be used with other additives to function as gas block agent, reduce logging acoustic amplitude and thus achieve good cementing quality.
