摘要
基于非平稳信号时频分析及其地震时频属性技术应用的有关研究成果,对地震信号时频分析、分频解释与频谱分解及其在地震沉积学与地震储层成像中的应用进行系统总结与阐述.从时频分析的基本原理出发,探讨地震分频解释和频谱分解的实现方法及其在地震沉积学与储层成像中的应用策略与效果.分析指出,发展高精度时频分析理论和算法,一体化统筹谋划地震资料叠前与叠后处理解释,针对不同地质条件探索相应的时频响应规律等,是分频解释技术及其在地震沉积学和地震储层成像研究中有效应用中值得深入研究的问题.
Based on the practice and knowledge of non-stationary signal processing, the seismic time-frequency analysis, interpretation with frequency decomposition and spectrum decomposition with the applications to seismic sedimentology and reservoir imaging research are surveyed. After introduction on the fundamentals of the seismic nonstationary analysis algorithms, the applied schemes to the seismic sedimentology and reservoir imaging are summarized. Then it is pointed out that there are some worthy subjects which should be focused on, including the time-frequency analysis method improvement, seismic processing and interpretation integration and the test under various geological conditions, so the time-frequency schemes and effects could be promoted greatly.
