A cross-linking composition comprises (a) an aqueous liquid, (b) a pH buffer, (c) a cross-linkable organic polymer, (d) a cross-linking agent which comprises an organic titanate, an organic zirconate, or combinations thereof, and (e) a delay agent which is a hydroxyalkylaminocarboxylic acid. The composition provides flexibility in rate of cross-linking and can be used over a wide range of pH. The composition is used in oil field applications for hydraulic fracturing and plugging of permeable zones and leaks in subterranean formations.
La présente invention concerne une composition de réticulation comprenant (a) un liquide aqueux, (b) un tampon de pH, (c) un polymère organique réticulable, (d) un agent de réticulation comprenant un titanate organique, un zirconate organique ou des combinaisons de ceux-ci, et (e) un agent de retardement qui est un acide hydroxyalkylaminocarboxylique. La composition confère de la flexibilité à la vitesse de réticulation et peut être utilisée sur une large plage de pH. La composition est utilisée dans des applications relatives au pétrole pour la fracturation hydraulique et le colmatage de zones perméables et de fuites dans des formations souterraines.
