摘要
在总结水驱控制程度计算方法的基础上,提出了运用体积法计算聚合物驱控制程度的方法。该方法既考虑了油层平面上的连通状况,又考虑了聚合物分子能够进入的孔隙体积大小。对于聚驱开发油层来说,使用聚驱控制程度方法要比沿用传统的水驱控制程度方法更能体现油层地质条件对聚驱效果的影响程度。
A method to calculate control degree of polymer flooding is described in this paper.This method is established on the basis of the method to calculate control degree of water flooding.Characteristics of polymer flooding in Daqing oilfield,the connectivity of the oil layer,and the porous volume that the polymer molecules can enter are considered in the method.Control degree of a polymer- flooding pilot can be better described with this method than that of the traditional water flooding control degree. According to the numerical simulation,the control degree of polymer flooding has great effect on the change of water cut and the enhanced oil recovery of polymer flooding. The control degree of polymer flooding is very important to design the injection plan and to predict the effect of polymer flooding.
