众所周知,阿尔奇公式F=a/φ~m (1)已应用多年。但是,其中指数m 的物理意义究竟是什么?以往涉及这个问题的文献(如[1]、[2])认为,只要通过理论导电模型的推导、岩心实验室分析或实际测井资科统计找出若于个影响m的因素,诸如孔隙度φ、渗透率K、孔道曲折度L_w/L、截面孔隙度A_w/A等,便可写出表达式 As we all know, Archie formula F = a / φ ~ m (1) has been used for many years. However, what is the physical meaning of the exponent m? In the past, the literature (such as [1], [2]) on this issue argues that as long as it is derived from the theoretical conductive model, core laboratory analysis or actual well logging statistic If a factor affecting m, such as porosity φ, permeability K, tortuosity L_w / L, cross-sectional porosity A_w / A, etc., we can write out the expression
