摘　　要：在试井分析中,通过特种识别曲线和图版拟合确定井筒储集系数,特种认别曲线理论上计算精度高,但对实际测试数据进行解释时,往往需要两种计算方法相互参考。而霍纳曲线则通常用来分析中晚期径向流阶段,对早期数据解释较为无力。现对霍纳曲线的半对数直线段进行研究,避开了早期实测数据波动的问题,提出了求取井筒储集系数的新方法,该方法对解决现场实际问题具有积极意义。In the well testing,the wellbore storage coefficient is often determined by the special identi-fication plate and matching curves,the former is higher accuracy in theory,but the best is often required to reference all the methods.the Horner plot is often used to analyze the radial flow in the late stage,more able to explain the early data.this paper studys the Semi-logarithmic straight line,and gives a new method avoiding the early undulatory date for well storage coefficient.
