(FR) COMPOSITIONS DE GUAR AUTO-HYDRATANTES ET AUTO-RÉTICULANTES ET PROCÉDÉS CORRESPONDANTS
Abstract
(EN)
A self-hydrating, self-crosslinking dry composition is used to prepare a hydrated, crosslinked fracturing fluid upon addition of water, the composition comprising (A) guar powder or a guar derivative powder; (B) crosslinker selected from the group consisting of boric acid, borax, borate ore, boron ore, antimony compounds, aluminum compounds, zirconium compounds, and titanium compounds; and (C) slow dissolving alkaline buffer, wherein the crosslinker (B) is non-encapsulated.
(FR)
La présente invention concerne une composition sèche auto-hydratante et auto-réticulante qui est utilisée pour préparer un fluide de fracturation hydraté et réticulé après l'addition d'eau, la composition comprenant (A) une poudre de guar ou une poudre de dérivé de guar ; (B) un agent de réticulation choisi dans le groupe constitué par l'acide borique, le borax, un minerai de borate, un minerai de bore, des composés à base d'antimoine, des composés à base d'aluminium, des composés à base de zirconium et des composés à base de titane ; et (C) un tampon alcalin à dissolution lente, l'agent de réticulation (B) étant non-encapsulé.
