叠后射线深度偏移与剩余偏移校正

RAY DEPTH MIGRATION AFTER STACK RESIDUAL MIGRATION CORRECTION

四川省地质调查处

本文介绍叠后射线深度偏移的计算方法,并提出利用现有偏移程序对时间偏移剖面作所谓剩余偏移校正的方法来完成深度偏移。

This paper aims at the computing technique for ray depth migration after stack. The depth migration is accomplished through what we called residual migration correction using existing migration programs for time migration sections.
