摘要
常规的倾角扫描大多在时间—空间域进行,本文利用地震剖面的时间—空间坐标与其二维傅里叶变换之间的对应关系,对常规频率—波数域滤波方法进行改进,在频率—波数域进行倾角扫描。通过理论模型计算和实际地震资料的处理,该方法在压制噪声干扰的同时,实现了在频率—波数域的倾角拾取,表明该方法是一种具有实用价值的方法。
The conventional dip-scanning is mostly used in the time-space domain.Using corresponding relationship between the time-space domain of seismic section and its 2-D Fourier transform,the paper improved the conventional filtering method in frequency-wavemumber domain and implemented dip-scanning in frequency-wavemumber domain.It is shown by theoretical model computation and processing of practical seismic data that the method realized the dip pickup in frequency-wavemumber domain while suppressing interferenc...
