Rheology and Stability of IOR Produced Liquid in Daqing Oilfield

摘要

Rheology and stability of some polymer flooding andrnASP(alkaline, surfactant, polymer) flooding produced liquidrnwere studied in this work. Rheology of the produced waterrnplays an important role in the stability of polymer flooding andrnASP flooding produced liquid. The stabilizing effect ofrnresidual polyacrylamide in produced water on o/w emulsionrndepends mainly on its influence on the bulk rheology ofrnproduced water, i.e. the viscosity and elasticity modulus of thernwater phase.
