依据达西定律，推导出计算地层渗透率公式，并列举现场实测资料进行了计算。结果表明，其方法和霍纳分析法比较，计算误差很小，为现场在进行ＳＦＴ测试后计算地层渗透率提供了一种简便、快速、实用的方法
Based on Darcy’s law, the formula for calculating the permeability of formation is deduced, and the field measured data are listed. The results show that compared with the method of Horner, the method has very small calculation error and provides a simple, rapid and practical method for calculating formation permeability after on-site SFT testing
