In this article, the viscosifying abilities, rheological properties, and flow characteristics of hydrophobic association water-soluble polymer with high association ability were studied using technical methods of viscosity measurement, rheological and core flow experiments. The results illustrate that hydrophobic associated polymers with low molecular weight rely on a strong hydrophobic interaction, the intermolecular and intramolecular micellar structure formed in solution with a strong ability to increase viscosity. Hydrophobic association water-soluble polymer, comparing with partially hydrolyzed polyacrylamides polymer with low molecular weight, presents a better ability of shear stability under the condition of shearing and the solution structure strengthens gradually so as to increase viscoelasticity remarkably. The hydrophobic association water-soluble polymer with high association ability take on greater injectivity and mobility control ability in low permeability porous media solving the problem of low injectivity and poor control ability in mid-low permeability reservoirs, which improves polymers flooding effect in such reservoirs and underlie the reasonable design of polymer molecular structure.
