摘　　要：采用恒速法进行物理模拟岩心驱替试验,分别测定多功能型聚合物驱油剂(FPS剂)、普通中分聚合物、超高分聚合物的滞留吸附特性,阻力系数及残余阻力系数,传导性能。试验结果表明,FPS剂具有较高的阻力系数及残余阻力系数,较强的可注入性,达到了控制流度比的目的;具有较好的传导性能,采用梯度式注入方式具有较好的调剖和"挖潜"驱油双重功能,有利于提高油层的波及体积,扩大波及效率,提高了原油采收率。The property remained adsorption,resistance factor and residual resistance factor and conducting characteristics of different Functional Polymer Surfactant(FPS)agents,medium molecular weight polymer and ultra-high molecular weight polymer were measured by the constant speed method based on core displacement experiments,oil displacement efficiency was studied by heterogeneous core model.The test results show that resistance factor and residual resistance factor of FPS agent are higher than medium molecular weight polymer.The injectivity of FPS agent is stronger enough for controlling the mobility ratio,FPS agent has better conductivity,and gradient injection method is used for tapping the potential of remaining oil,improving reservoir sweep volume,expanding swept efficiency and enhancing oil recovery.
