地震资料处理中子波的有效提取和反褶积计算

The Algorithm about Wavelet and Deconvolution in the Seismic Data Processing

提取地震子波是数据分析和处理的关键,采用不同的子波提取计算方法,比较不同算法求取子波同原始子波间的差异,分析其原因和问题所在;另外通过反褶积获取新的地震记录,对比剖面分辨率的变化情况。其主要目的是提供相关处理参数的算法,比较之间的差异和优劣,寻求最佳匹配算法,计算精度是本文的重点。

The seismic wavelet extraction is a key factor to the seismic data analysis and process.In the paper,the wavelets appear different among the value through several operation methods to get to wavelet.Therefore,the analysis of relative reason and suggestion will be done further.What＇s more,the important algorithm will be operated how to gain new seismic records after deconvolution.At the same time,the contrast analysis of the profiles resolution change will be made.To achieve the best matching algorithm and to improve operation precision,the operation methods of relative procession parameters will be offered for reference,and it will be clear to know the differences between them.
