摘要
鉴于对石油羟酸盐－碱－部分水解聚丙烯酰胺（ＨＰＡＭ）二元复合体系的流度控制未曾有过探讨，在实验室内研究了这种三元复合体系在有残余油和无残余油时通过多孔介质渗流的特性。通过实验确定了其阻力系数及有效粘度。结果表明，能与原油产生超低界面张力的石油羟酸盐三元复合体系在有残余油时的阻力系数以及阻力系数与残余阻力系数的比值明显减小；该复合体系在有残余油和无残余油时通过多孔介质渗流的有效粘度均低于粘度计测定的粘度。
It has been showed by laboratory research that the resistance factor and the effective viscosity of a petroleum carboxylate/alkaline/HPAM flooding system flowing through porous media both in and without presence of residual oil have been investigated.The resistance factor and the ratio of the resistance factor to residual resistance factor of the flooding system in presence of residual oil are decreased substantially. The effective viscosity of the system flowing through porous media both in and without presence of residual oil is lower than the viscosity measured by viscometer.
