摘要: 针对石油地震勘探中信号的时变性,提出了一个新的时变地震信号反褶积方法.在分析地层时变滤波特性的基础上,构造多尺度地震子波,分别用每一尺度的地震子波作确定反褶积,并基于信息最小熵准则设计检测函数,综合多尺度反褶积结果。理论数据和实际资料处理表明本文提出的方法具有较好的效果。Abstract: The multi -measure seismic wavelet is established through analysis of stratigraphic time - varing fitering characteristics, and the deconvolution is determined by cach wavelet, then, based on minimum entropy criterion,the detection function is established, the integrated multi - measure result is obtained. the real datas processing show that the method has good effect.
