角度作为描述裂隙走向的参数, 在各向异性研究中是非常重要的, 利用它可以有效地分离快慢横波, 求取各向异性参数。提出了一种利用三分量资料求取裂隙走向的方法———角度谱, 阐明了角度谱的概念、原理及求取方法, 最后给出了参数选择和质量控制方法。

Angle, a parameter that is used to describe fracture strike, is a key parameter in anisotropic research. With angle information, the fast and slow shear waves can be effectively separated, and anisotropic parameters can be determined. This paper proposes a method called angular spectrum to estimate fracture strike on three-component seismic data. The concept, principle, and calculation method of angular spectrum is discussed. The methods for parameter selection and quality control is also presented.
