| 摘 要： | 建立光滑可渗透平行板单裂隙新模型,以此为基础分析介质间流体交换对基质岩块渗透性和单裂隙导流能力的影响,推导出两者的等效渗透率修正公式,并对不同裂隙开度和间距下的裂隙介质渗透性进行分析,研究介质间流体交换对裂隙介质渗流的影响.结果表明,当裂隙开度大于250μm或裂隙间距大于1.36 cm时,可忽略介质间流体交换对裂隙介质渗流的影响.

| Abstract: | A new single fracture model was set up,namely a smooth parallel plate model with permeable rock matrix.Based on this model,the impact of fluid exchanging process on the permeability of the rock matrix and the flow conductivity of single fracture were analyzed.And then the equivalent permeability formulas of rock matrix and single fracture were obtained.The permeability of fractured porous medium with different fracture aperture and spacing was analyzed,and the influence of fluid exchanging process on the se... |
