Research and Application of Coherent Attribute Fusion Technology Wavelet Transform Coherency

由于小波变换在图像融合领域中具有良好的效果,同时基于地震体属性的相干技术在识别断层、微裂缝、岩性和岩相变化等特征方面具有优势。论文将小波变换和相干技术进行结合,对相干属性的图片进行融合。通过实践证明,基于小波变换的相干属性融合技术可以突出特定频带的信息,可反映不同层次的地质特征,在检测断层和裂缝方面有着较好的应用前景。

In view of the excellent effects of wavelet transform in the image fusion field,coherent techniques based on seismic body properties are superior in identifying features such as faults,micro-cracks,lithology and lithofacies.In this paper,the wavelet transform and coherence techniques are combined to fuse the pictures of the coherent attribute.It is proved by practice that the co⁃herent property fusion technology based on wavelet transform can highlight the information of specific frequency bands,reflect the geological features of different levels,and has a good application prospect in detecting faults and cracks.
