摘要
地震波速度参数贯穿于地震数据采集、处理和解释的整个过程,是地震勘探中最重要的参数之一。主要对叠加速度分析、偏移速度分析和速度层析反演三大类典型的速度分析方法的基本原理、发展及应用条件等作简要的回顾与介绍。在复杂地质构造及低信噪比资料情况下,提高速度分析的精度和计算效率是当前及未来研究的重点。
Seismic velocity is one of the most important parameters in seismic exploration,because it is used in the whole course of seismic exploration,including seismic data acquisition,pro- cessing and interpretation.This paper reviewed the theory,de- velopment and applications of 3 typical velocity analysis tech- nologies,stack velocity analysis,migration velocity analysis and tomographic inversion.To cope with complex geology and low S/N data,it will be the focus of research to improve the computation precision and efficiency of velocity analysis at present and in the future.
