Temperature salt-resistant polymer

the use of water preparation EOR oil products to meet the mining out of water recycling

Temperature salt-resistant polymer is to address the use of water preparation EOR oil products to meet the mining out of water recycling ,in order to facilitate the environmentor to the high salt and high-temperature oil field for EOR polymer blocks, and resolve ASP flooding in the ternary system was developed to maintain a high viscosity products.
