| 摘 要： | 不同于用品质因数Q的方法来对地层吸收特性和地震波衰减规律进行研究，采用的方法为，首先把对象确定在近地表层，然后把近地表层当成一个系统，并在此基础上利用工区内的微测井资料设计一个能消除近地表衰减吸收的反滤波器，在求出工区内每一口微测井所对应的反滤波器后，利用所有反滤波器在不同平面位置以及不同深度上的百分比振幅谱信息来研究近地表层的吸收衰减规律。

| Abstract: | Different from the method that uses Q-factor to study formation absorption features and seismic wave attenuation rules,the method in this paper is firstly to fix target at near surface,then treat near surface as a system.Based on this,an inverse filter that can eliminate near surface attenuation absorption is designed by using micro-logging data in work area.After each micro-logging corresponding inverse filter in work area is determined,the percentage amplitude spectrum information of all inverse filters at different planimetric positions and depths are used to study near surface absorption attenuation rules. |

| Keywords: | seismic wave attenuation rule micro-logging data inverse filter frequency spectrum |
