【摘要】 纹理分析是图像处理中的一种常用技术,通过构建地震纹理基元和灰度共生矩阵,可以将此项技术推广到地球物理领域,并可在断层识别,边缘检测和沉积相划分等方面得到应用。这里通过算法研究和程序开发,结合JJD工区应用实例,得到了有一定理论意义和研究价值的结论:①基于灰度共生矩阵提取的纹理属性,是一种很好的凸显断层和裂缝信息的地震属性;②可以根据实际地质问题,提取不同方向的纹理属性,并用RGB技术进行多属性的融合;③地震纹理基元的窗大小取9×9×9为好;④要根据具体情况选取合理的灰度级别,对于常规三维地震数据,灰度级别取16或32比较理想。更多还原

【Abstract】 Texture analysis is a common technology in image processing,which can be extended to the field of geophysical prospecting by constructing seismic texture primitive and gray level co-occurrence matrix.It can be used in fault identification,edge detection and sedimentary facies delineation.Through the algorithm research,programming and practical application,we get some conclusions which has theoretical meaning and valuable ①The texture attribute which based on gray level co-occurrence matrix is a good attribute in highlighting the information of faults and fractures,② According to actual geological problems,we can extract texture attributes of different directions,and use RGB technology for the integration of multi-attributes,③ The window of seismic texture element we should adopt is 9×9×9,④ We should select a reasonable level of gray of different conditions,and commonly selection is 16 or 32 for conventional three-dimensional seismic data.更多还原
