VERWENDUNG VON CSH-SUSPENSIONEN IN DER BOHRLOCHZEMENTIERUNG
The use of a setting accelerator composition for inorganic binders, which comprises at least one water-soluble comb polymer suitable as plasticizer for hydraulic binders and calcium silicate hydrate particles in the development, exploitation and completion of underground petroleum and natural gas reservoirs and also for deep wells is proposed. The use according to the invention not only accelerates the setting and curing of cement slurries but also shortens the time in which the static gel strength of the cured cement slurries increases from 100 lb/100 ft2 (4.88 kg/m2) to 500 lb/100 ft2 (24.4 kg/m2).
