针对任意排列的三维地震记录,假设一个横向和纵向不均匀的各向同性宏观速度模型,我们提出一种保幅地震反射成像的综合法。方法由二部分组成:(1)将地震反射数据从测量的时间域变换(偏移)到模型深度域的加权克希霍夫绕射叠加积分;(2)将偏移
For arbitrary arranged 3D seismic records, assuming an isotropic macro-velocity model with lateral and longitudinal heterogeneity, we propose a synthetic method for amplitude-preserving seismic reflection imaging. The method is composed of two parts: (1) a weighted Kirchhoff diffraction superposition integral of the seismic reflection data from the measured time domain transform (offset) to the model depth domain; (2)
