| 摘 要： | 提高地震信号的分辨率是地震勘探要解决的一项主要任务,而提高地震信号的信噪比是提高地震信号分辨率的先决条件。要提高地震资料的信噪比,需要去除地震资料中的相干噪声和随机噪声。本文介绍了平稳小波变换结合阈值压制面波干扰的方法,通过实际地震记录的处理证实了该方法的有效性。

| Abstract: | Improving the resolution of seismic signal which should be solved in a seismic exploration is a major task,and improved signal to noise ratio(SNR) of seismic signal is the prerequisite to improve seismic signal resolution.To improve the SNR of seismic data,the coherent noise and random noise in seismic data will need to be removed.This paper introduces the suppress ground-roll jamming methods based on the stationary wavelet transform combined with threshold.The processing results of real data show that the ... |
