金属矿地震勘探技术方法研究综述 ——散射波地震勘探方法

介绍了地震波散射的概念、散射波特征、散射波与反射波的区别等散射波地震方法的基础内容，分析了金属矿地震波场复杂的散射特征。对散射波地震方法研究和应用现状进行了评述，指出散射波资料采集和成像技术是目前散射波地震方法技术研究的主要内容，总结了散射波资料采集的要求和处理难点。特别强调了已有的较为成熟的反射波成像技术不能直接用于散射波地震资料处理，应开展有针对性的散射波成像技术研究。研究表明，基于等效偏移距的偏移方法(EOM)在速度分析和偏移成像方面具有独特的优势，为散射波成像方法研究提供了思路。

Review of seismic survey in mining exploration: Part 2 Scattered wave seismic exploration

This paper reviewed the definitions of seismic wave scattering,and investigated the characteristics of scattered wave,its differences with reflected wave,and the complex scattering behaviors of metallic ore seismic wave field.Studies and applications of scattered wave method were summarized.Acquisition and imaging techniques are the key contents in research on scattered wave seismic.Requirements and difficulties in scattered wave data acquisition and processing were presented.The author pointed out that the mature reflection imaging techniques are not suitable for imaging scattered wave,and scattered wave imaging approaches are yet to be developed.Equivalent offset migration(EOM)method,which has particular advantages in velocity analysis and imaging,provides ideas for scattered wave imaging.
