Title (EN) METHOD OF DELAYING CROSSLINKING IN WELL TREATMENT OPERATION
(FR) PROCÉDÉ POUR RETARDER LA RÉTICULATION LORS D'UNE OPÉRATION DE TRAITEMENT DE PUITS
Abstract: front page image
(EN)Crosslinking of a crosslinkable viscosifying agent and a crosslinking agent may be delayed in a well treatment fluid by incorporated within the fluid a glutamic-N,N- diacetic acid salt, such as a glutamic-N,N-diacetic acid sodium salt like tetrasodium glutamate diacetate. The crosslinking agent may be a zirconium containing crosslinking agent like zirconium (IV) acetyl acetonate. The viscosifying agent may be guar or a guar derivative such as carboxyalkyl guars and hydroxyalkylated guars like carboxymethyl guar, hydroxypropyl guar, hydroxyethyl guar, hydroxybutyl guar and carboxymethylhydroxypropyl guar.
(FR)Selon l'invention, la réticulation d'un agent rendant visqueux réticulable et d'un agent de réticulation peut être retardée dans un fluide de traitement de puits par l'incorporation, dans le fluide, d'un sel d'acide glutamique-N,N-diacétique, tel qu'un sel de sodium de l'acide glutamique-N,N-diacétique comme le glutamate-diacétate tétrasodique. L'agent de réticulation peut être un agent de réticulation contenant du zirconium comme l'acétylacétonate de zirconium (IV). L'agent rendant visqueux peut être le guar ou un dérivé de guar tel que des carboxyalkylguars et des guars hydroxyalkylés comme le carboxyméthylguar, l'hydroxypropylguar, l'hydroxyéthylguar, l'hydroxybutylguar et le carboxyméthylhydroxypropylguar.
