在现代试井解释中，典型曲线拟合技术是一个很有用的方法。当透明纸的实际数据图和理论典型曲线图达到一个最佳拟合时，我们可以任进一个拟合点（M），而拟合点的四个数据（P_D，t_D/C_D，ΔP和Δt）可在两张图上读得。直到目前为止，典型曲线拟合技术仅能用于计算相应的地层有效渗透率（K）、井筒储集常数（C）和表皮系数（S），而不能确定地层压力，在本文中提出了一个利用典型曲线图确定地层压力的方法。这样，典型曲线图在实际中的应用范围将会得到扩大。
In modern well interpretation, the typical curve fitting technique is a very useful method. When the actual chart of the transparent paper and the theoretical typical curve achieve a best fit, we can fit in a fitting point (M) and the four data of the fitting point (P_D, t_D / C_D, ΔP and Δt ) Can be read in two pictures. Up to now, the typical curve fitting technique can only be used to calculate the corresponding effective formation permeability (K), wellbore storage constant (C) and skin factor (S), but can not determine the formation pressure. In this paper, The method of using typical graphs to determine formation pressure. In this way, the typical application of the curve will be expanded in practice.
