3 d seismic volume data

Because of influence of aperture of migration operator, the image of 3-d seismic data volume in space is smeared after migration, which is unfavorable for detecting the faults.

但由于偏移算子的孔径影响，经偏移得到的三维地震数据体在空间上被模糊了，不利于进行断层检测。

Sub-volume coherence is one of seismic coherence resulted from the coherence calculation of one sub-volume of any size with another sub-volume in 3-D seismic data volume.

子体相干技术以三维地震资料中任意尺寸的子体为基本计算单元，求取与其他子体之间的地震属性相干结果。

The method can readily get access to the aribitry cross sections from the 3-D seismic data volume and display it.

该方法便于访问和显示三维地震数据体任意方向的剖面。
