摘 要: | 采用数值比较,利用反解需洛伦兹曲线建立数学模型,通过对数据的分析总结非均质油藏开发的规律。结果表明:均质油藏的划分标准是当渗透率变异系数小于或等于0.2时;当含水率剖面与渗透率剖面相同的时候,无论是正韵律油藏还是反韵律油藏其注入水的方式都是通过高渗透层,正韵律油藏比反韵律油藏的含水率剖面坡度更大。

Abstract: | In this paper, numerical comparison is used to establish a mathematical model by using the reverse solution of the Lorentz curve, and the law of heterogeneous reservoir development is summarized by analyzing the data. The results show that when the permeability variation coefficient of homogeneous reservoir is less than or equal to 0.2, when the water cut profile is the same as the permeability profile, both positive rhythm reservoir and reverse rhythm reservoir inject water through the high permeable layer, and the water cut profile gradient of positive rhythm reservoir is larger than that of reverse rhythm reservoir. |
