波动方程叠加偏移及应用中的几个问题—关于波动方程偏移之一

SOME PROBLEMS CONCERNING THE WAVE EQUATION MIGRATION AND ITS APPLICATION

本文略述波动方程叠加偏移有限差分法在国产一五○电子计算机上的实现,着重讨论实际资料处理过程中的几个问题,即差分格式稳定性问题,速度参数对偏移结果的影响,剖面中的弧形干扰现象.

This article deals with the realization of the finite difference method of the wave equation migration by use fn the model 150 computer made in China. Special attention has been paid to the discussion of the problems concerning the processing of the practical materials, namely, the stability of the difference scheme, the influence to the results of the migration owing to the velocity and the arc interference on the profile.
