| 摘 要： | 应用二维正交小波包技术对地震信号进行压缩，压缩的效果与选择的正交小波、地震数据以及阈值有关。地震信号压缩２０倍左右，从视觉上是可以接收的，不会引起较大的失真。恢复的剖面是一个小波滤波剖面，比原剖面有更好的信噪比，此方法能同时达到压缩数据和提高信噪比的目的，且计算速度快，稳定性好，自适应性强，能对各种地震数据进行压缩。

| Abstract: | The compression of a seismic data by means of two-dimensional orthogonal wavelet packet algorithm is discussed. Computation results show that it is an efficient method. Compression ratio generally is between 15 and 30. Restored section can be acceptied from the visual view.In fact, it is a wavelet filtered section. Compared with original section, the signal-noise ratio is improved evidently. |
