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

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。

In order to reduce the influence of layer interference to development effectiveness when the layers which have different permeability are developed combined.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.
