Title (EN) STORABLE LIQUID CEMENTITIOUS SLURRIES FOR CEMENTING OIL AND GAS WELLS
(FR) PATES DE CIMENT LIQUIDES, STOCKABLES, DESTINEES A CIMENTER DES PUITS DE PETROLE ET DE GAZ
Abstract:
(EN) In the method of the invention, a storable hydraulically-active cementitious slurry is made and used to cement within subterranean foundations for oil and gas wells. The slurry is made from hydraulically-active, cementitious material suitable for oil field purposes and can be stored until needed. During storage, the slurry remains liquid. The slurry is activated when needed for cementing. After pumping the activated slurry into the wellbore, the set cement has properties acceptable for well cementing.
(FR) Selon le procédé de l'invention, on fabrique et on utilise une pâte de ciment stockable, hydrauliquement active, pour cimenter l'intérieur des fondations souterraines des puits de pétrole et de gaz. La pâte de ciment est obtenue à partir d'un liant hydraulique, actif, approprié pour être utilisé dans les champs de pétrole et qui peut être stocké jusqu'au moment de son utilisation. Lors du stockage, la pâte de ciment reste liquide. La pâte de ciment est activée au moment nécessaire pour procéder à la cimentation. Après le pompage de la pâte de ciment activée dans le puits de forage, le ciment pris a des propriétés acceptables pour cimenter des puits.
