摘　　要：合成地震记录的精度直接影响地震地质层位的准确标定,精度较高的地震记录必须要有准确度较高的子波。主要介绍了多道统计法提取子波的具体实现步骤,并且利用实际地震资料用多道统计法提取子波后,合成地震记录以及进行层位对比,实际资料处理结果表明了该方法的正确性和有效性。The accuracy horizon labeling of seismic and geologic position was affected directly by the precise of synthetic seismogram;however,the high precision seismic records should have a higher accuracy wavelet.the specific steps of multi-track statistical method was mainly described for extracting the wavelet and taking the advantage of the method for synthetic seismograms and layer correlation.The result shows that the method is accurate and valid.
