Disclosed is a cement composition comprising polymeric particles with inorganic fillers for application in oil well cementing. The fillers improve bonding between the polymeric particles and the cement matrix leading to improved mechanical parameters of the cement system. The filled particles may also lead to improved mixability and slurries that are easier to optimise.

L'invention porte sur une composition de ciment renfermant des particules polymères avec des charges inorganiques pour une application dans la cimentation d'un puits de pétrole. Les charges améliorent l'adhérence entre les particules polymères et la matrice de ciment, ce qui conduit à des paramètres mécaniques améliorés du système de ciment. Les particules chargées peuvent également conduire à une miscibilité améliorée et à des barbotines qui sont plus faciles à optimiser.
