A Study on Shear Resistance Characteristic of Hydrophobically Associated Water-Soluble Polymer

Abstract

Abstract: The characteristics of shear recovery and resistance of hydrophobically associated polymer (AP4) in lab fresh water and simulated reservoir brine are tested. The experimental results show that AP4 in both conditions has good behaviors for shear thinning and shear resistance compared with partially hydrolyzed polyacrylamide (HPAM), more indicating that the hydrophobical association effects greatly on shear resistance behavior, and this polymer for oil-gas recovery can be allowed to implementation and application of it for oilgas recovery.

Key words: polymer, shear velocity, quality concentration, shearing degradation
