■ High temperature strength
■ Controllable crosslinking time
■ High crosslinking strength
The product is divided into two kinds of alkaline crosslinking and acidic crosslinking. The alkaline crosslinked organic zirconium is made by complexing inorganic zirconium with complexing agent under certain conditions, and the water-soluble plant gum polymer containing cis-ortho hydroxyl and carboxyl on the structural unit is crosslinked under weak alkaline conditions to form fracturing fluid gel. Acidic crosslinked organic zirconium is formed by complexing inorganic zirconium with organic coordination under certain conditions, and crosslinking reaction with polyacrylamide derivatives under weak acid conditions to form fracturing fluid gel.
