混合相位子波处理一直是地震信号数字处理中的一个重要课题。对此，国内外学者进行了许多研究，并提出了不同的解决方法。本文在分析已有各种子波处理方法优缺点的基础上，提出了一种新的估算剩余混合相位子波相位的算法。利用这种方法对地震信号子渡进行相位校正，可使子波接近或达到零相位，从而消除了剩余相位的影响，提高了地震记录的分辨率。经理论模型及实际资料的试算结果，证实了此方法是行之有效的。
Hybrid phase wavelet processing has been an important issue in the digital processing of seismic signals. In this regard, scholars at home and abroad conducted many studies and proposed different solutions. Based on the analysis of the advantages and disadvantages of various existing wavelet processing methods, a new algorithm for estimating the phase of residual mixed-phase wavelet is proposed. Using this method, the phase of seismic sub-crossing is corrected, and the wavelet can approach or reach zero phase, so as to eliminate the influence of residual phase and improve the resolution of seismic record. The theoretical model and actual data of the trial results, confirmed that this method is effective.
