针对碳酸盐岩的多孔储层试井解释,建立了三重介质非牛顿-牛顿流体复合油藏渗流模型,得到了Laplace空间的解析解,并通过Stehfest数值反演算法,利用Matlab绘制了各种参数影响下的无因次压力及压力导数的典型曲线,最后分析了各个参数在典型曲线上的压力响应特征。
Aiming at the well test interpretation of carbonate reservoirs, a triple-media seepage model of non-Newtonian-Newtonian compound reservoir was established. Analytical solutions of Laplace spaces were obtained. The Stehfest numerical inversion algorithm and various Matlab The typical curves of dimensionless pressure and pressure derivative under the influence of parameters are analyzed. Finally, the pressure response characteristics of each parameter on typical curves are analyzed.
