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.
The fluctuating surface is a common problem in the collection, processing and interpretation of seismic data.The numerical simulation of seismic wave propagation under undulating surface is of great significance to seismic data processing and interpretation of fluctuating surface observation.Seismic wave field simulation and seismic wave walking time field respectively describe seismic wave Dynamics and kinematics information are two important ways to study the theory of seismic wave propagation.This paper reviews and summarizes the research progress of numerical simulation methods of seismic wave propagation under undulating surface from two aspects of seismic wave field and seismic wave walking time field, Some of the latest research results in the field, in order to allow readers to find a breakthrough point for the ups and downs of the surface of the exploration of classical problems to contribute.
