基于油藏数值模拟技术的渗透率级差组合界限研究

摘要：为了减小不同渗透率油层组合开发时层间干扰对于开发效果的影响。本文利用ECLIPSE数值模拟软件，通过概念模型，研究了渗透率级差与开发效果之间的关系，给出了渗透率的级差界限。结果表明：对不同渗透率油层组合开发时，固定最小渗透率，渗透率级差上限为3；固定最大渗透率时，渗透率级差上限为8。

Research on the boundary of Permeability Max-min Ratio Based on Numerical Simulation Technology

Abstract: In order to reduce the influence of Layer interference to development effectiveness when the layers which have different permeability are developed combined. In this paper, the numerical simulation software---ECLIPSE is used to study the relationship between permeability Max-min Ratio and development effectiveness. The boundaries of the permeability max-min ratio are also given. The results show that when the layer which has lower permeability is fixed, the upper boundary of permeability Max-min Ratio is 3; when the layer which has higher permeability is fixed, the upper boundary of permeability Max-min Ratio is 8.
