利用正演模型研究VSP处理
|
摘要
VSP是一种井中地震观测技术,其独特的观测方式,决定了VSP处理也有别于常规地震,最明显的就是VSP资料必须经过波场分离,才能利用下行波或上行波信息对资料进行解释和反演。除波场分离外,VSP还有许多其它独特的处理环节。基于PC-VSP系统,进行了VSP模拟,在正演数据的基础上,研究了VSP处理,取得了较好的效果。
VSP is a borehole seismic survey technology.Because of its special survey way,VSP processing is quite different from conventional seismic survey,and the most different is that it is necessary for VSP data to be processed with wavefield separation, after which,downgoing wave or upgoing wave can be used for interpretation and further inversion.Besides,VSP has many other special processing steps.With PC-VSP system,VSP modeling has been done and further research on VSP processing has also been finished on the basis of forward modeling data,obtaining good final processing results.
