Deconvolution is a principal technique to compress seismic wavelet for the enhancement of vertical resolution.Seismic data can be described by a convolution model,i.e.seismic data are the convolution of a reflection coefficient series with a seismic wavelet.The impulsive response of earth is the primary information for seismic exploration.Therefore,it is important to extract reflection coefficient series from seismic data.

Deconvolution is a principal technique to compress seismic wavelet for the enhancement of vertical resolution.Seismic data can be described by a convolution model,i.e.seismic data are the convolution of a reflection coefficient series with a seismic wavelet.The impulsive response of earth is the primary information for seismic exploration.Therefore,it is important to extract reflection coefficient series from seismic data. The blue filter operator can be calculated through the simulation of coloured components of the reflection coefficient series.Convolving to seismic data processed with deconoolution,a result achieved is better than a simple deconvolution process.The synthetic tests and real data applications show the method works better in high resolution processing.

反褶积是通过压缩地震子波以提高地震数据纵向(时间)分辨率的过程。地震数据可以用褶积模型来表示,即地层反射脉冲与地震子波的褶积。而地震脉冲(反射系数)包含了石油勘探和地震研究中必不可少的有关大地地球物理性质的信息,因此,从地震数据中得到反射系数就变得非常有意义。蓝色滤波通过对反射系数有色成分的模拟,得到与反射系数有色成分有关的蓝色滤波算子。然后对经反褶积处理后的地震数据进行褶积运算,就能获得比常规反褶积方法好得多的结果。通过对合成地震记录和实际地震数据的试验,证明了本方法在高分辨率处理方面具有较好的效果。

The raw seismic data from the center of Tarim desert are low in signal-to-noise ratio, resolution, and fidelity. Effective waves are smeared due to their low energy, therefore they are poor in continuity and difficult to identify on seismic sections. A series of measures has been taken. The raw seismic data were preconditioned to eliminate the effects of interference waves and varied altitude. Poststack data were further refined by data processing method such as coherency enhancement, polynomial fitting, radial...

The raw seismic data from the center of Tarim desert are low in signal-to-noise ratio, resolution, and fidelity. Effective waves are smeared due to their low energy, therefore they are poor in continuity and difficult to identify on seismic sections. A series of measures has been taken. The raw seismic data were preconditioned to eliminate the effects of interference waves and varied altitude. Poststack data were further refined by data processing method such as coherency enhancement, polynomial fitting, radial predictive filtering, dip filtering, elimination of random noise, poststack deconvolution, frequency compensation, time-variant spectral whitening, blue filtering, amplitude compensation, which increase the dominant frequency of effective waves from 20 Hz to 40 Hz. Proper work flow of data processing and processing parameters were determined by test.

塔中沙漠地区地震原始资料的信噪比、分辨率、保真度低,有效波不突出,能量弱,连续性差,在叠加剖面上难以追踪。针对这些问题,采取了一系列有效措施。首先,通过预处理对原始资料进行净化,消除由各种干扰波和地表高差大给资料造成的影响,使单炮记录的信噪比、分辨率和保真度得到了提高;然后,通过速度分析和选择合适的叠加方式得到具有较高信噪比、分辨率和清晰度的叠加剖面;最后,对叠后数据体进行细化处理,采用相干加强、多项式拟合、径向预测滤波、倾角滤波、随机噪声衰减、叠后反褶积、频率补偿、时变谱白化、蓝色滤波和振幅补偿等处理手段,使最终的叠加剖面有效波主频从20Hz提高到40Hz。通过大量的试验分析,制定了适合于塔中地区地震资料的处理流程和参数。
