基于广义S变换的地层吸收补偿

广义S变换是一种新的非平稳信号时频分析方法。广义S变换的反变换与傅立叶变换有直接的联系，是无损变换；线性变换保证其不存在交叉项；时频分辨率与信号的频率有关；基本小波不必满足容许性条件；尺度性质使得广义S变换有很好的频率聚集能力。基于广义S变换的特点和优势，进行地层吸收补偿。通过对实际二维叠后地震数据进行地层吸收补偿处理，结果表明，提高了地震反射层的分辨率，改善了地震资料的品质，而且无需知道地层的Q值。 

Stratigraphic absorption-compensation based on the generalized S-transform

The generalized S transform is a relatively new time-frequency analysis method for non-stationary signal, which has the following characteristics and advantages:S transform inverse transform and Fourier transform are directly linked to ensure that it is the non-destructive transform; linear transform ensures that there is no cross-terms; time-frequency resolution and the signal frequency-related; basic wavelet does not have to meet the permitted conditions; scale makes the generalized S transform have good aggregation ability for frequency.This paper uses this method for stratigraphic absorption-compensation based on these characteristics and advantages.Through the processing of stratigraphic absorption-compensation for actual two-dimensional poststack seismic data, results show that this method can do well on absorption-compensation, improve the resolution of seismic reflection without the Q value of the Strata.
