摘要
将三维地震数据体用图像的形式表达,储层裂缝信息表现为图像的边缘特征,通过边界保持滤波技术与基于构造属性约束滤波技术相结合对数据体进行去噪处理,提高信噪比、突出边界信息,在此基础上应用Laplacian边缘检测算法实现对小断层的精细识别与刻画,解决了以往相干技术识别裂缝模糊的问题,为地震解释提供了新方法、新思路。
When 3D seismic data volume is expressed by image form, reservoir fracture information will display as image edge fea-ture. The combination of boundary filtering technology and constraint filtering technology based on structural attribute will be used to denoise data object, improve signal noise ratio （SNR）, highlight boundary information. On this basis, Laplacian edge detection al-gorithm can realize fine identification and depiction of small faults, thereby resolving the problem of recognizing fracture fuzzy and providing new methods for seismic interpretation.
