But polymer solution is viscoelasticity and non-Newtonian fluid,routine water drive separate injection technology is about forming orifice pressure difference and controlling influx through decreasing open area,so the problem of high viscosity loss factor（40～70%）and the affection on displacement effectiveness is existence.
但对于聚合物溶液这种粘弹性非牛顿流体,如果采用常规水驱分层注入技术(即通过减小过流面积来形成节流压差、控制注入量)进行分层注入,存在着粘度损失率高(40～70%)、影响驱替效果的问题。
