Abstract

Abstract: In view of the practical problem of choosing the medium-low molecular weight salt-tolerance polymer for Changqing Jurassic reservoir with low permeability and high salinity, this paper systematically analyzed the influence of ion concentration and composition on the salt-tolerance behavior of three different medium-low molecular weight salt-tolerance polymers. The measurement results of viscosity, relaxation time, fluorescence and environmental scanning electron microscopy showed that, compared with the conventional salt-tolerance polymer SAV55 and the associative polymer EY-131 with lower molecular weight, the associative polymer BHXF-850 with higher molecular weight and associative monomer content had better viscosifying capacity. However, with the addition of Na⁺, Ca²⁺ and Mg²⁺, the viscosity retention rate, relaxation time and solution structure number of BHXF-850 were the lowest and the structural strength was also the weakest, and the solution microstructure was significantly affected by the addition of ions. At the same time, the salt-tolerance behavior of the polymer had no obvious difference between the addition of mono-valent and divalent ions. The findings can provide reference for the optimization of medium-low molecular weight salt-resistant polymers used for chemical flooding in reservoir fields.

Key words: Jurassic reservoir, ion composition, medium-low molecular weight, salt-tolerance polymers, relaxation time, solution structure, micro-structure
