本文论述了最大熵原理在地震资料处理中三个方面的应用。最大熵频谱计算所产生的频谱很尖锐,在短时窗时,它比傅氏变换频谱的分辨率要高得多。最大熵反褶积具有很好的时适应性,尤其是把它用于经过最小相位转换以后的地震记录,可以获得最佳的分辨率。用最大熵方法恢复波阻抗时,只适用于地层反射很稀疏6号情况,它的实用价值尚待进一步检验。
This paper discusses the application of maximum entropy principle in three aspects of seismic data processing. The spectrum generated by the maximum entropy spectrum calculation is very sharp, and its resolution is much higher than that of the Fourier transform spectrum in short time windows. Maximum entropy deconvolution has good temporal adaptability, especially when it is applied to the seismic record after the minimum phase shift to obtain the best resolution. When using the maximum entropy method to restore the wave impedance, it is only suitable for the situation that the formation reflection is very sparse, and its practical value needs to be further tested.
