Title (EN) FOAMED CEMENT COMPOSITIONS CONTAINING METAL SILICIDES USABLE IN SUBTERRANEAN WELL OPERATIONS
(FR) COMPOSITIONS DE CIMENT MOUSSÉ CONTENANT DES SILICIURES MÉTALLIQUES UTILISABLES DANS DES OPÉRATIONS DE PUITS SOUTERRAIN
Abstract:
(EN) Cement compositions containing a metal silicide such as an alkali metal silicide or an alkaline earth metal silicide. Upon mixing with water, the metal silicide reacts to generate hydrogen gas, a silicate, and heat - each of which is advantageous for the large variety of uses to which cements are put. The invention relates to a foamable cement composition comprising about 99.999 wt% to about 98.5 wt % of a cement, and about 0.001 wt % to about 1.5 wt% of a metal silicide or a mixture of metal silicides. Concretes and grouts containing the cement composition are also disclosed. Other embodiments provide methods for forming cement structures, including in subterranean formations and wells.
(FR) L'invention concerne des compositions de ciment contenant un siliciure métallique tel qu'un siliciure de métal alcalin ou un siliciure de métal alcalino-terreux. Lors du mélange avec de l'eau, le siliciure métallique réagit pour générer de l'hydrogène gazeux, un silicate et de la chaleur - dont chacun est avantageux pour la large diversité d'utilisations auxquelles les ciments peuvent servir. L'invention concerne une composition de ciment moussable comprenant environ 99,999% en poids à environ 98,5% en poids d'un ciment, et environ 0,001% en poids à environ 1,5% en poids d'un siliciure métallique ou d'un mélange de siliciures métalliques. L'invention concerne également des bétons et coulis de ciment contenant la composition de ciment. D'autres modes de réalisation concernent des procédés pour former des structures de ciment, y compris dans les formations souterraines et les puits.
