Abstract:

The shear degradation and recovery characteristics of amphiphilic polymers with various structure and concentration have been described, and the shear-resistance and viscosity-recovery performances of the supramolecular systems based on amphiphilic polymers have been introduced. Considering the actual oilfield factors, such as injection rate, temperature, salinity, and aging time, the shear characteristics and viscosity-recovery performance of amphiphilic polymers under the influence of various factors have been summarized. Finally, the development trend of anti-shear amphiphilic polymers has been prospected, which can provide theoretical and technical basis for the design and application of anti-shear amphiphilic polymers.

Key words: amphiphilic polymer, shear degradation, shear recovery, influencing factor
