■ Strong resistance to temperature and salt
■ Strong ability to reduce acid filtration
The product is a polyacrylamide derivative obtained by homopolymerization of a salt-resistant cationic monomer. It is white powder and has the characteristics of temperature resistance and salt resistance. It can be quickly dissolved in acid and water with high viscosity. In the acidification operation of oil and gas wells, it can effectively reduce the loss of acid fluid to the formation, slow down the reaction speed of acid and reservoir, increase the spread area of acid fluid, and improve the acidification effect.
