在聚合物驱油过程中，注入液体沿着高渗透带或大孔道渗透，长期无效循环，低渗透带未被波及，导致聚驱后仍有相当一部分储量未被动用。为了提高剩余油的动用程度，可采收调剖的方法，利用高分子聚合物堵住高渗透带或大孔道，使注入液体向低渗透带波及，搞高波及体积，进而提高采收率。本文主要从物理实验和数值模拟两个方面来研究调剖对后续提高采收率的可行性。

In the process of polymer flooding, the injection of liquid along high permeability zones or large hole penetration, inef ective circulation for a long time, low permeability zone has not been affected, cause there are stil quite a number of reserves after polymer flooding has not been used. In order to improve the use of residual oil, can harvest the method of profile control, the use of polymer block the high permeability zone or big channel, make the injection liquid to low permeability zone affected, high reflection and volume, and then improve oil recovery. This article mainly from two aspects of physical experiment and numerical simulation to study the feasibility of profile control on subsequent improve recovery factor.
