基于谱分解与信息融合的生物礁有利相带识别技术

摘要

通过讨论连续小波变换和RGB融合技术的原理,提出将地震数据通过谱分解变换到频率域,提取振幅谱和相位谱属性,并利用RGB融合得到的综合属性识别生物礁有利相带.结合研究区实际资料处理,结果表明:综合属性具有较高的图像显示清晰度,特征明显、细节丰富,能更清楚地刻画生物礁有利相带的边界.%This paper introduces the continuous wavelet transformation and RGB fusion technique, and proposes transforming seismic data into frequency domain through spectral decomposition and then extracting amplitude spectrum and phase spectrum, and identifying reef favorable facies belt with comprehensive properties by RGB. The research indicates that comprehensive properties have a high image definition, evident characteristics and great details, which clearly depicts favorable facies belt boundary of organic reef.
