摘要
针对目前复杂边界、平面非均质、不规则井网条件下水驱面积波及系数一直缺乏准确计算方法的现状，结合油藏工程方法，利用动态数据得到水驱曲线反求能够代表复杂边界、平面非均质、不规则井网条件下的相对渗透率曲线，进而计算出水驱面积波及系数。结合油藏数值模拟结果，对理论计算结果进行了对比。结果表明，提出的计算方法在数学上比较简单，计算结果较为可靠。
At present, the accurate calculation methods for the areal sweep efficiency of water flooding under the conditions of complex boundaries, areal heterogeneity and irregular well pattern are absent. This paper proposes a new method to calculate the areal sweep efficiency of waterflood. With the application of reservoir engineering meth- od, the water drive curves can be obtained based on dynamic data, and the relative permeability curves that can re- present the conditions of complex boundaries, areal heterogeneity and irregular well pattern will be got, and then the areal sweep efficiency for water flooding can be calculated. The method is verified by comparing the results of reservoir numerical simulation with theoretical results. From the comparison, the method presented in this paper is quite simple with satisfactory accuracy.
