基于递归滤波的工频噪声压制方法研究OA北大核心CSCDCSTPCD
Industrial noise suppression method based on recursion filtering
在老油区地震勘探中,工频噪声干扰严重影响了地震资料的品质.压制工频噪声的常规方法是陷波处理,该方法在压制噪声的同时对有效信号损伤很大.另一类基于正弦或余弦函数逼近的工频噪声压制方法,通常假设工频噪声的振幅、频率和相位保持固定不变,在实际资料处理时其适用性受到很大限制,并且计算量较大,算法效率不高.在分析已有方法的基础上,提出了一种基于递归滤波的工频噪声压制方法,利用工频噪声的周期性,导出递归滤波器,并对递归滤波算子作适当修改,保证了滤波器的稳定性…查看全部>>
The quality of seismic data is often influenced by industrial noise in old oilfield exploration. Notch-filtering is commonly used for removing industrial noise and leads to damage the effective signal. Methods based Cosine or Sine function approach is only adaptable to the cases that the amplitude, frequency and phase of industrial noise are stable. The adaptability of the method was limited during actual data processing and it has the disadvantage of large …查看全部>>
