过去,在处理深海域的地震资料时,一般是采用“反向消去法”或“深水波形预测反褶积法”来消除鸣震。但是,当鸣震和反射波互相干涉时,这些方法的效果不理想。为了改善这类资料的处理效果,本文提出一种新的“深海预测反褶积法”。与上述两种方法比较,这种方法所要求的前提条件少,应用的范围更广泛。理论分析和模型试验的结果表明,这种方法的效果是令人满意的。
In the past, when dealing with seismic data in deep-sea areas, it is common to eliminate the squawkhts using either the “reverse cancellation method” or the “deep-water waveform predictive deconvolution method.” However, these methods do not work well when the sonic and reflected waves interfere with each other. In order to improve the processing effect of this kind of data, this paper proposes a new “deep sea prediction deconvolution method.” Compared with the above two methods, this method requires fewer preconditions and a wider range of applications. Theoretical analysis and model test results show that the effect of this method is satisfactory.
