Gelling Agent

Brief Introduction:

It has high molecular weight and good viscosifying effect.

GENERAL

AZVI-04High molecular weight polyacrylamide for EOR is prepared by using a unique formula and advanced process. The integrated indexes and performance of the product meet and even exceed those of the comparable product available at home and abroad. The product has been applied and propularized in tertiary recovery.

APPLICATION

AZVI-04 has high molecular weight and good viscosifying effect. It has short dissolving time, little water-insoluble residue and low filter coefficient and has better tolerance to temperature, salt and shear than those of the comparable products available.

 

PACKAGE

Packed in moisture proof sacks (25 kg for each), with PE film lining inside.
