(FR) COMPOSITIONS DE CIMENT CHARGÉ COMPRENANT DES PARTICULES APTES À GONFLER DANS L'HUILE ET PROCÉDÉS CORRESPONDANTS
Abstract: front page image
(EN)A variety of methods and compositions are disclosed herein, including, in one embodiment, a method of cementing in a subterranean formation comprising: providing an extended cement composition comprising cement, water, an oil-swellable particle, and a set retarding additive, wherein the extended cement composition is capable of remaining in a pumpable fluid state for at least about 1 day; adding a cement set accelerator to the extended cement composition; introducing the extended cement composition into a well bore; and allowing the extended cement composition to set. Another embodiment comprises an extended cement composition comprising: cement; water; an oil-swellable particle; and a set retarding additive, wherein the extended cement composition is capable of remaining in a pumpable fluid state for at least about 1 day.
(FR)L'invention porte sur divers procédés et compositions, comprenant, dans un mode de réalisation, un procédé de cimentation dans une formation souterraine comprenant les opérations consistant à : se procurer une composition de ciment chargé comprenant du ciment, de l'eau, des particules aptes à gonfler dans l'huile et un additif retardateur de durcissement, la composition de ciment chargé étant capable de rester à l’état de fluide pompable pendant au moins environ 1 jour ; ajouter un accélérateur de durcissement de ciment à la composition de ciment chargé ; introduire la composition de ciment chargé dans un puits de forage ; et laisser la composition de ciment chargé durcir. Un autre mode de réalisation comprend une composition de ciment chargé comprenant : du ciment ; de l'eau ; des particules aptes à gonfler dans l'huile ; et un additif retardateur de durcissement, la composition de ciment chargé étant capable de rester à l’état de fluide pompable pendant au moins environ 1 jour.
