| 摘 要： | 简要介绍用正交偶极声波计算地层应力的方法原理，并给出一段计算应力剖面的实例。通过计算表明该方法与过去相比不同。在泥岩段水平最大与最小主应力基本相等或相差甚小，在砂岩段才呈现较大差异。对该方法计算结果与技术发展给出粗浅的看法。

| Abstract: | A method for in-situ stress calculation using cross-dipole acoustic logs is described in this paper. This method has been applied to a shale formation. Calculation results show differences between this method and prior ones. Horizontal maximum and minimum principal stresses are nearly equal in shale formation, and very different in sand formation. The results of this method and its developing trend are discussed. |
