摘要
本文对一个盐丘侧翼模型的VSP数据成像进行了理论试算和分析,试算的结果表明了VSP数据波动方程偏移方法的可行性,展示了该方法的效果和潜力。
Migration is a process whereby events in image space are mapped into their correct positions in 'object space'. The wave equations associated with this mapping may be defined and solved, numerically either in image space or in Object space.This paper describes a reverse—time migration(RTM) method whereby VSP data are analysed and computed by the author. Based on the results of the Computation, it is shown that the RTM method is computationally efficient.
