Title (EN) SLURRY COMPRISING AN ENCAPSULATED EXPANSION AGENT FOR WELL CEMENTING
(FR) BOUE COMPRENANT UN AGENT D'EXPANSION ENCAPSULÉ POUR LA CIMENTATION DE PUITS
Abstract: front page image
(EN) Methods to prepare a well cementing slurry include coating particles comprising an expanding agent with a component selected from the group consisting of a phenolic resin, a silica, a calcination product of a polysiloxane oil, and a combination thereof; and combining the coated particles with mix water and hydraulic cement to form a cement slurry for cementing a well.
(FR) L'invention concerne des procédés de préparation d'une boue de cimentation de puits consistant à enduire des particules comprenant un agent d'expansion avec un composant choisi dans le groupe constitué par une résine phénolique, une silice, un produit de calcination d'une huile de polysiloxane et une association de ceux-ci; et à combiner les particules enduites à un mélange d'eau et de ciment hydraulique pour former une boue de cimentation pour permettre la cimentation d'un puits.
