多种地震资料处理软件中的速度分析

Velocity analysis in different seismic data processing software

速度分析是地震资料处理中的重要一环,速度分析的质量直接影响动校正继而影响叠加成像以及偏移归位。本文论述了不同的处理软件(以PROMAX、FOCUS、CGG软件为例)中速度分析的方法,并比较了它们的优劣,这对我们处理不同品质的资料具有很大的帮助。

Velocity analysis is a very important moveout and static correction and further on the step in seismic data processing. Its quality influences the stack imaging and migration. This article discusses velocity analysis methods in different processing software （take PROMAX,FOCUS,CGG software as example）, and compares their advantage and disadvantage, which help us to process different quality seismic data.
