摘要:

起伏地表是地震数据的采集、处理和解释中普遍遇到的难题.起伏地表下的地震波传播数值模拟,对起伏地表观测的地震资料处理解释有重要意义.地震波场模拟和地震波走时场分别描述地震波的动力学和运动学信息,为研究地震波传播理论的两种重要途径.本文从地震波场和地震波走时场两方面回顾和总结了起伏地表下的地震波传播数值模拟方法的研究进展,并展示了该领域的一些最新研究成果,为使读者能从中找到突破点,为起伏地表这一勘探领域的经典难题做出贡献.

Abstract:

Rough topography is very common and we have to deal with it during the acquisition, processing, and interpretation of seismic data. Modeling of seismic-wave propagation in medium with irregular topography is beneficial to process and interpret seismic data acquired by active and passive source seismology conducted in areas of interest such as mountain ranges and basins. Seismic wavefield and seismic wave traveltime field are two important ways to describe seismic wave propagation. In this paper, we try to give a basic review on the research progress of seismic wave propagation simulation method through the above two aspects, and show some new research results in this field, in the meaning of supplying a initial material so as to enable readers get some basic knowledge of the development obtained in the past and current, and find some breakthroughs then may make some contributions to the development or applications of new methods and technologies themselves.
