开展了基于小波分频技术的地层Q值补偿方法研究.首先应用小波分频技术将浅层、中深层和深层地震数据分成不同的 频率段,得到不同目标层频率区间的地震数据,然后利用地层Q 值提取技术提取Q 值,最后分别进行地层Q 值振幅补偿和相位 补偿.该方法针对不同的目标层将地震资料分成不同的频率段,避免了不同频率成分地震信号的相互影响,同时特殊对待目标 层的频率信息,提高了地层Q 值提取的稳定性.模型试算和实际资料应用表明,该方法能够有效补偿不同目的层地震数据,使 浅、中、深层反射波形基本一致,主频提高,频带展宽,从而提高了地震数据的质量.

英文摘要：

The method of formation Q value extraction based on wavelet frequency division technology mainly divides seismic data into different frequency segments for the different target layer, to avoid the interaction of different frequency component in seismic data. By specifically treating the frequency information from target layer,the stability of the formation Q value is improved. Based on this, we aim at the shallow,middle and deep,deep target layer,using wavelet frequency division technology to divide the data in-to different frequency bands？obtain seismic data with different frequency interval of the target layer.Then we use the extraction technology of formation Q value to extract Q value and finally amplitude compensation and phase compensation are carried out re-spectively using the Q value. The results of model test and example analysis show that the method can effectively compensate the seismic data from different target layers,which makes the reflection wave shape consistent,the main frequency improved,the fre-quency band broadened, thus improving the quality of seismic data.
