Acid thickening agent

Product features

This product is a kind of cationic or amphoteric copolymer solid powder, which is used in acidizing or acidizing fracturing process, for acid compression (chemical) transformation of carbonate reservoir, to delay the reaction rate and filtration rate of acid and reservoir rock. The product can quickly dissolve in acid, increase viscosity, with high temperature resistance (120-150℃), salt resistance, good compatibility, outstanding friction resistance, can effectively reduce acid/rock reaction speed and acid filtration speed, expand the acid treatment radius.
