When three oil flooding encounters new NuoerPAM products

China is already the country with the largest production and use of PAM, and the Nuoer Group is one of the representative manufacturers of large-scale production of PAM. According to the survey, most of China's PAM products are used in tertiary oil displacement, and a small part is used in papermaking, textile printing and dyeing, coal washing, chemical, municipal wastewater and other sewage treatment.

However, ordinary PAM encounters high temperature, has salt, and will decompose, reduce viscosity, and become thin when shearing. This is a short board in tertiary oil recovery. Because the formation temperature of the tertiary oil recovery is high and the salinity is large, a large shear force is generated during the process of transporting to the formation. This is not possible with ordinary PAM. It is very important to study new products resistant to high temperature and salt.

The temperature and salt-resistant polymer produced by Nuoer Group is a high-performance polymer oil-displacing agent prepared by adding functional structural units such as inhibiting hydrolysis, complexing high-valent cations, increasing rigidity of rigid molecular chains, and strong hydration ability in AM. The research and application of temperature and salt resistant PAM is of great significance for improving oil production and oil production rate.
