d volume data

The processing has been done on the basis of 3-D migrated data volume with 48 well-connecting lines being selected.

本次处理工作是在三维偏移数据体的基础上，抽取48条连井线进行。

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。

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。
