【摘要】 传统复地震道方法提取的地震瞬时属性存在物理意义不明确、对噪声敏感等不足,本文探讨基于经验模态分解的地震瞬时属性提取方法,得到不同尺度下的地震瞬时属性,由此得到的瞬时频率在数值上与地震主频对应较好.将该方法提取的属性应用到海上地震数据中,显示出较好的效果.更多还原

【Abstract】 The seismic attributes from the traditional complex seismic trace method are lack of clear physical meaning and sensitive to noise.A new method of extracting seismic instantaneous attributes based on empirical mode decomposition is discussed in this paper.Seismic instantaneous attributes on different scales are gained and the instantaneous frequency accords with seismic dominant frequency well.The new method for seismic attributes is applied to marine seismic data and exhibits good performance.更多还原
