Abstract
Salt-resistant polymer is a functional polymer developed for high-temperature and high-salt reservoirs. The molecular structure and composition are the essential factors that determine its performance. The performance needs to be explained from the salt resistance mechanism. For salt-resistant polymers with unknown molecular structure and composition, clear molecular structure characterization and component analysis are important prerequisites for the analysis of their salt-resistant mechanism. In addition, the molecular size of the salt-resistant polymer is an important factor in determining its compatibility with the reservoir. In this paper, based on a series of characterization and analysis methods, the molecular structure characterization and component analysis of different unknown salt-resistant polymers were carried out, and the molecular sizes of different polymers were determined by dynamic light scattering, in order to provide a better understanding of the salt-resistant polymers of different salt-resistant polymers. Mechanism analysis and polymer reservoir matching analysis provide theoretical basis and reference.
