在分析常规利用RGB混频显示技术整合分频信号的应用效果及局限性基础上,提出将三参数小波频谱成像技术与信息融合技术结合应用来预测地质异常体空间展布的新方法。该方法首先构造三参数小波进行地震资料的频谱分解从而得到不同频率小波域的高精度地震信号。在此基础上利用基于模糊逻辑理论的信息融合算法来整合得到的分频信号,最终结果以概率的形式对地质异常体的展布特征进行精细定量刻画,实际资料的应用效果证明了该方法的有效性和实用性。
Based on the analysis of the application effects and limitations of conventional RGB mixing display technology to integrate the frequency-divided signals, a new method of combining the three-parameter wavelet spectral imaging technology and information fusion technology to predict the spatial distribution of the geological anomalies is proposed. The method first constructs a three-parameter wavelet for spectral decomposition of seismic data to obtain high-precision seismic signals in different frequency wavelet domains. On the basis of this, we use the information fusion algorithm based on fuzzy logic theory to integrate the obtained frequency-divided signals. The final result gives a detailed and quantitative description of the distribution features of geological anomalies in the form of probability. The application results of actual data prove that Validity and practicality.
