在连续介质情况下的真振幅恢复

THE TRUE AMPLITUDE RECOVERY IN CONTINUOUS MEDIA

作真振幅恢复时,若所用的数学模型是建立在均匀介质的基础之上,则由于这种假设与复杂的地下实际情况相差甚远,真振幅恢复往往是不理想的。 本文所述是基于连续介质情况下比较精确的数学模型。文中述及的几项试验,说明采用此方法的依据。 最后,我们用这种数学模型处理了一些地震剖面,并做了简单的效果分析。从分析结果看来是取得了初步的效果。这就说明了这种数学模型是可取的。

The mathematical models used while conducting true amplitude recovery were mostly based on homogeneous media. There is a world of difference between the assumption and actual situation underground which is assumed to be quite complicated. Therefore, the result is usually far below expectation whenever amplitude recovery with such kind of model is applied.This paper deals with the available mathematical medel resorting to continuous media. The experiments mentioned hereinabove have proved the scientific basis for the adaptation of the method being discussed.In conclusion, some seismic sections were processed by means of the mathematical model and its accuracy has been verified. As a result of verification, we can see the first fruits have been reaped. So the results show clearly that the mathematical model is recommendabe as well as desirable.
