风化层对地震波的吸收十分强烈，补偿风化层对地震波的吸收，可以提高地震记录的分辨率。反演风化层的品质因数Q是补偿吸收作用的重要一步。现今有很多反演Q值的方法，但各种方法求出的Q值的可靠性均与信噪比有关。当记录信噪比较低时，没有任何一种现行方法能求出可靠的Q值。本文提出一种考虑噪声干扰近地表风化层的Q值反演方法，并用理论记录和实际记录作了实验，得到了较好的效果。
Weathered layer of the seismic wave absorption is very strong, to compensate for the weathering layer of seismic wave absorption, can improve the resolution of seismic records. The quality factor Q of the inverted weathering layer is an important step in compensating for the absorption. There are many methods of inverting Q values today, but the reliability of the Q values obtained by various methods is related to the signal-to-noise ratio. When the recorded signal-to-noise ratio is low, no current method yields a reliable Q value. In this paper, we propose a Q-value inversion method to consider the near-surface weathered layer with noise interference. Experiments with theoretical recording and actual recording have been done and good results have been obtained.
