摘　　要：聚合物溶液的残余阻力系数是指当其通过多孔介质时,因为滞留或堵塞造成多孔介质对水渗透率下降的度量。残余阻力系数越大,油层渗透率下降就越大,如果残余阻力系数过大,就会造成油层的阻塞,不利于聚合物驱。通过推导数学公式以及开展流动实验等,对于聚合物溶液流经岩心后的残余阻力系数进行了预测,对于在驱油过程中聚合物的选取有一定的指导意义。The residual resistance coefficient of polymer solution is the decline level of water phase permeability of porous media caused by detention or blocking of polymer solution after it flowing through porous media. The bigger the residual resistance coefficient is, the greater the declining degree of reservoir permeability is. If the residual resistance coefficient is too big, the oil layer will be blocked, which is bad for polymer flooding. In this paper, a mathematical formula was derived, and flow experiments were also carried out. The residual resistance coefficient of the polymer solution after it flowing through the core was predicted.
