| description | Disclosed is a composition and a method for cementing a casing in a borehole of a well using an aqueous cementing composition comprising (a) water, (b) a cementing composition comprising (i) a hydraulic cement, (ii) a hydrophobically modified polymer, (iii) a dispersant, and optionally (iv) one or more other additives conventionally added to aqueous cementing compositions useful in cementing casings in the borehole of wells. Preferably the hydrophobically modified hydroxyethyl cellulose has an ethylene oxide molar substitution of from 0.5 to 3.5, a hydrophobe degree of substitution of from 0.001 to 0.025, and a weight- average molecular weight of from 500,000 to 4,000,000 Daltons and the dispersant is sulfonated polymer, melamine formaldehyde condensate, a naphthalene formaldehyde condensate, a branched or non-branched polycarboxylate polymer. Preferably, the aqueous cementing composition is pumped downwardly into said casing, pumped upwardly into the annulus surrounding said casing until said aqueous composition fills that portion of the annular space desired to be sealed, and then maintaining said aqueous cementing composition in place until the cement sets.
L'invention concerne une composition et un procédé pour cimenter un cuvelage dans un trou de forage d'un puits à l'aide d'une composition de cimentation aqueuse comprenant (a) de l'eau, (b) une composition de cimentation comprenant (i) un ciment hydraulique, (ii) un polymère modifié hydrophobiquement, (iii) un dispersant et, éventuellement, (iv) un ou plusieurs autres additifs généralement ajoutés aux compositions de cimentation aqueuses utilisées pour la cimentation des cuvelages dans les puits de forage de puits. De préférence, l'hydroxyéthylcellulose modifiée hydrophobiquement présente une substitution molaire d'oxyde d'éthylène de 0,5 à 3,5, un degré de substitution hydrophobe de 0,001 à 0,025, une masse moléculaire moyenne en poids de 500 000 à 4 000 000 de Daltons, et le dispersant est un polymère sulfoné, un condensat de mélamine formaldéhyde, un condensat de naphtalène formaldéhyde, un polymère de polycarboxylate ramifié ou non ramifié. De préférence, la composition de cimentation aqueuse est pompée vers le bas dans le cuvelage, il est pompé vers le haut dans l'espace annulaire entourant le cuvelage jusqu'à ce que la composition aqueuse remplisse la partie de l'espace annulaire que l'on souhaite sceller, puis la composition de cimentation aqueuse est maintenue en place jusqu'à la prise du cim |
