ZOC-FlexCem™ Latex polymer cement slurry system is composed of ZOC-G81L and ZOC-G80L as basic additives, latex ZOC-GR5 and ZOC-GR6 as core additives, retarding agent, dispersing agent and other additives as auxiliary additives. Latex polymer cement slurry system not only has the advantages of wide range of temperature, high temperature and salt resistance and performance stable of the multi-functional system, but also has the latex system’s functions of strong impact toughness in cement sheath. The system has better performance of reducing water loss, compactness, strong toughness, low permeability of the cement paste through the combined action of polymer’s adsorption on cement particles and latex particles’ filling effect on cement gaps so as to improve cementing quality effectively and prolong the production life of oil well. The ZOC-Flex system is mostly used in liner cementing required good cementing quality, oil layer cementing and other well cementing operation with special requirements.
