双渗分形油藏动态数学模型的精确解

ACCURATE SOLUTION TO THE DYNAMIC MATH MODEL OF DUAL PERMEABILITY FRACTAL RESERVOIR

将非线性分形理论应用于描述油藏非均质渗流中 ,通过分析和考虑油藏的实际渗流情况 ,引入分形维数Df 和分形指数θ来描述油藏的分形特征和油藏非均质性 ,在此基础上 ,建立了双渗分形油藏的渗流数学模型 。

The non linear fractal theory was applied to fluid flow in heterogeneous reservoir. Through analyzing the fluid flow in real reservoir, the fractal dimension df and fractal index were introduced to describe the fractal characterization and reservoir heterogeneity, according to which the dynamic math model of dual permeability fractal reservoir was established. Consequently, the math model accurate solution was presented by using orthodox transform method.
