METHOD FOR STABILIZATION OF POLYMER SOLUTION Russian patent published in 1995 - IPC

Abstract SU 1716861 A1

FIELD: oil producing industry; polymer flooding of oil fields. SUBSTANCE: introduced into polymer solution is polyhexamethylene guanidine with molecular mass of 20-50 thou. Concentration of polyhexamethylene guanidine in polymer solution is 10-100 mg/1. EFFECT: higher stabilization of polymer solution due to preservation of polymer solution viscosity in formation conditions. 3 tbl
