本文根据交联聚合物溶液的流变性及聚合物滞留引起的油层渗透率的降低,应用流体力学及平面径向流的理论,提出一个预测注入压力的计算方法,为分析具有较高粘度的流体向油层注入的可行性提供了理论依据。
In this paper, based on the rheology of crosslinked polymer solution and the decrease of reservoir permeability caused by polymer retention, a new method for predicting injection pressure is proposed by applying the theory of fluid mechanics and radial flow. In order to analyze the effect of fluid with higher viscosity The feasibility of injecting into the reservoir provides the theoretical basis.
