通过调研国内外相关文献,列举出三种典型的双重介质渗流数学模型。针对每种模型的特点及适用性作出相应评价,同时比较各双重介质模型的优缺点。根据实例,比较各模型下压力及压力曲线示意图。对比分析可知,De Swaan渗流模型能更好地适用于页岩气藏。%Through the study of the related literatures at home and abroad, the paper enumerates three traditional dual medium flow models. The paper compares each model＇s advantages and disadvantages, also makes evaluations about the applicabilities and features of the flow models. According to the calculation example, the pressure and pressure curves are compared. Through the anlysis, we come to a conclusion that the de Swaan model is better for the shale gas reservoir.
