高分辨率资料处理与高信噪比资料

目前有很多提高地地震资料分辨率的方法，如谱白化，外推展谱和小波变换等等。但不论何种方法，制约提高分辨率的主要因素是地震资料的原始信噪比，而不完全依赖所使用的处理方法。高分辨率地震勘探是一项系统工程，需要野外采集，室内处理等各方面的共同的努力才能实现，其中高质量的数据采集是最基础性的工作，是目前所有处理方法无法替代的，在处理方法上如何绕过线性滤波范畴和克服常规叠加中非同相叠加因素的影响，是进一步提高

High-resolution data processing and high signal/noise ratio data

There are many methods for raising the resolution of seismic data,such as spectrum whitening, extrapolated spectrum , wavelet transform, and so on. In anymethod,seismic resolution essentially depends on signal/noise ratio of raw seismicdata,but has something to do with the processing methods we use. High-resolutionseismic exploration involves good data acquisition,advanced data processing and soon, of which good data acquisition is the most important. In the data processing,both avoiding the.use of linear filtering technique and eliminating the influence dueto outphase stacking are necessary to improving the signal/noise ratio of seismic data and to achieving high-resolution seismic exploration.
