Firstly, the amplitude spectrum of the seismic .wavelet is fitted by least squares method according to the relationship between the autocorrelation of the seismic records and the autocorrelation of the seismic wavelet, and then the autocorrelation of the seismic wavelet is computed anew. Secondly, a minimum phase filter is designed by using computed autocorrelation of the seismic wavelet, a delay is added to the dominant diagonal of the autocorrelation function, a minimum phase filter is decomposed into a short filter and is convoluted with a longer filter, resulting in a series of mixed phase wavelets and a mixed phase filter. Finally, the resulted mixed phase filter is convoluted with raw seismic traces, and an optimal mixed phase filter and an associated mixed phase wavelet are selected. The model test and the real data processing show that the mixed phase deconvolution is better than the minimum phase deconvolution., authors=null, authorsList=null, authorCompany=null,

articleAbstract=实际地震资料处理中的子波是混合相位，对此提出一种改进的混合相位反褶积流程。在地震道中抽取一个标准道，利用谱模拟的方法求出地震子波的自相关；利用计算子波的自相关，设计了一个最小相位的滤波器，增加一个延迟量于自相关函数主对角线上，将最小相位滤波器分解为一个长度很短的滤波器和一个长度较长滤波器的褶积，得到一系列混和相位的子波和混和相位滤波器；将这些混和相位滤波器与原始地震道进行褶积，选出最佳的混和相位滤波器。通过理论模型与实际地震资料对比，证明混和相位反褶积优于最小相位反褶积。,
