摘要
用地震子波对时移地震非一致性造成的影响进行了模拟。将影响因素概括为 4种形式 ,即时移、相位变化、振幅量级不一致、频宽不一致。采用互均衡技术对以上 4种情况进行校正 ,达到了理想的效果 ,为实际资料的处理和方法研究奠定了理论基础。
In the paper, we stimulatd the effects of time lapse seismic non repeatability through seismic wavelet. The effect factors can be classified into four categories: time shift, phase variation, difference of amplitude magnitude, difference of frequency width. Cross equalization processing is adopted to eliminate the differences and satisfactory results have been achieved. This study forms a foundation for practical data processing and method studying.
