双重孔隙

The flow problem of fluids flow in a fractal reservoir with double porosity
双重介质分形油藏渗流问题
The pseudosteady state flow problem of coalbed gas in deformed media with double porosity
变形双重介质煤层气拟稳态渗流问题
In the paper each mathematic model of seepage in fractured rock masses is summarized . finite element analysis simulation equations of non - double porosity system model - equivalent continuum media model and discrete fracture network model are given , furthermore a coupling uniform model is formed which integrated with the merit of the two former models
本文综述了裂隙岩体渗流分析的各类数学模型，对于非双重介质模型? ?等效连续介质模型和离散裂隙网络模型分别给出了它们的有限元模拟公式，还进一步提出了结合上述两种模型优点的适用于复杂裂隙岩体的耦合统一模型。
