摘　　要：通过室内实验 ,研究了聚合物驱和三元复合驱采出水流变性及采出液的稳定性。实验结果表明 ,水相流变性对聚合物驱和三元复合驱采出水和采出液的稳定性有显著影响。聚合物对O/W型原油乳状液的稳定作用 ,主要是通过增强原油乳状液水相的流变性 (如视粘度、弹性模量和屈服值 )The water-phase rheology and stability of the produced liquid from some polymer flooding and ASP(alkaline,surfactant,polymer)flooding were studied.The water-phase rheology plays an important role in the stability of the produced liquid.The stabilizing effect of residual polyacrylamide in water-phase on the O/W emulsion depends mainly on its influence on the bulk rheology of the produced water-phase,ie.,the viscosity and elasticity modulus of the water-phase.
