摘要
用于非均质油藏产量计算的Joshi公式,不适用于水平渗透率各向异性的油藏上,建议采用将水平渗透率乘以校正系数(α=(K_x/K_y)^-n)的方法,对Joshi公式进行修正,该方法简便可行,适于常规应用.
Joshi formula for calculating production rate in heterogeneous reservoir doesn't adapt for reservoir with anisotropy horizontal permeability. It is suggested that Joshi formula should be corrected by multiplying horizontal permeability by correction factor(d = n Kx/Ky).This method is simple and feasible for application.
