Title
(EN) STRENGTH RETROGRESSION MITIGATION MATERIALS FOR CEMENT COMPOSITIONS
(FR) MATÉRIAUX D'ATTÉNUATION DE LA RÉTROGRESSION DE LA RÉSISTANCE MÉCANIQUE POUR LES COMPOSITIONS DE CIMENT
Abstract
(EN)
Cement compositions for use in subterranean wellbores that include a monophase amorphous hydraulic binder material (MAHBM). The MAHBM may include a plurality of particles having a silica core and an amorphous coating substantially surrounding the silica core. The coating may comprise a plurality of amorphous particles, such as α-dicalcium silicate hydrate nanoparticles or microparticles. The MAHBM may be used as a strength retrogression mitigating additive in a cement composition or used as a high temperature cement.
(FR)
L'invention porte sur des compositions de ciment destinées à être utilisées dans des puits de forage souterrains qui comprennent un matériau liant hydraulique amorphe monophase (MAHBM). Le MAHBM peut comprendre une pluralité de particules comportant un noyau de silice et un revêtement amorphe entourant sensiblement le noyau de silice. Le revêtement peut comprendre une pluralité de particules amorphes, telles que des nanoparticules ou des microparticules de silicate alpha-dicalcique hydraté. Le MAHBM peut être utilisé en tant qu'additif d'atténuation de la résistance à la rétrogression dans une composition de ciment ou utilisé en tant que ciment à haute température.
