消除水层鸣震问题是海洋地震资料处理的重要课题之一。本文提出用反向消去法,即用一种相关分析法消除深海鸣震现象。我们在DJS-11计算机It对理论模型做了多次试验,效果较好。本方法的优点是所要求的前提较少,缺点是当鸣震与其它波形叠加在一起时,处理效果不理想。本方法是参考国外有关资料,作了相应改进后提出的,文中具体介绍了实现本方法的各个步骤。
Eliminating the issue of the ringing of the water layer is one of the most important topics in ocean seismic data processing. In this paper, the reverse elimination method is proposed, that is, a correlation analysis method is used to eliminate the deep-sea loud-earthquake phenomenon. We did a lot of experiments on the theoretical model at DJS-11 computer, which worked well. The advantage of this method is that fewer prerequisites are required. The disadvantage is that when the acoustic shock and other waveforms are superimposed together, the processing result is not satisfactory. This method is based on the relevant foreign information, made after the corresponding improvements made, the paper describes in detail the steps to achieve this method.
