相干能量梯度与属性比例融合在断裂构造解释中的应用

相干能量梯度体现了相干数据的振幅变化，它比较有利于突出一些细小的地质特征变化，其属性比例融合是将两个数据体按照一定比例融合在一起生成新的数据体，而新数据体能更好的反映地质特征。实例表明，与相干属性相比，相干能量梯度属性对一些细小构造更敏感，而且可以根据不同方向、时间的切片对不同走向的断层进行追踪；与常规地震时间剖面相比，属性比例融合后的属性剖面，可以在剖面中显示两种属性体的断裂构造特性，减少单一属性体的不确定性。

Application of Coherent Energy Gradient and Attribute Proportional Integration in Faulted Structure Interpretation

The coherent energy gradient has embodied amplitude variation of coherent data,propitious to carry out some small geologi-cal features variation;the attribute proportional integration is to integrate two data volumes in certain proportion into a new data volume that can reflect geological features better. Case studies have demonstrated that compared to coherent attribute ,coherent energy gradi-ent attribute is more sensitive to minor structures,also can carry out tracing faults with different strike according to slices of different direction,different time. Compared with conventional time section,attribute section after attribute proportional integration can reflect faulted structural characteristics of two kinds of attribute volume on section,reduce uncertainty of single attribute volume.
