By this method, it is capable for calculating the initial rock stress, i. e., vertical stress, average horizontal stress, maximum and minimum horizontal stress, in any depth below surface.
该方法弥补了以往各向同性球壳模型的不足，可计算出任意深度的原岩应力状态：铅垂应力、平均水平应力、水平面内最大及最小正应力。
By use of minimum quadratic multiplication the inflexion depth to temperature curve can determined that can interpret the vertical crack height.
通过逐一确定井温曲线拐点达到确定裂缝高度的目的。利用最小二乘法可以确定井温曲线拐点深度，从而可以解释垂直裂缝高度。
