摘要
相比较早的小波变换和傅氏变换,广义S变换具有更好的时频局部性,但也存在低频信息易损失、弱反射层易丢失等问题。对基于广义S变换的地震高分辨率处理方法进行了改进,提出了新的处理思路。这种基于广义S变换的高分辨率处理技术,在提取并补偿高频信号的同时,也对低频信号进行了有效的保持。该项技术在流花11-1油田取得了良好的应用效果。
Compared with the earlier wavelet transform and Fourier transform, generalized S transform is better in time-frequency locality, but is easier to lose low frequency information and to miss weaker reflections. Therefore, the method of sesmic high-resolution processing based on generalized S transform was improved and a new idea of processing was developed. Using this improved method based on generalized S transform, high frequency signals can be extracted and compensateed, and simultaneously low frequency signals are effectively maintained. This improved method was applied in LH11-1 oilfield, resulting in good effects.
