山东海洋学院

折射波叠加是折射波法地震勘探的一种新方法, 它利用共接收点多次复盖方法和数字处理技术对资料进行自动分析和解释, 最后输出时间剖面和深度剖面。从而提高了折射波法勘探的灵敏度、信噪比和分辨率。本文阐述了折射波叠加偏移的基本原理和处理方法, 并给出了模拟试验的结果。

The stacking of refraction is a new technique in seismic refraction exploration. By using the technique of multiple coverage of common receiver point and the technique of digital processing, the data analysis and interpretation could be carried out automatically and the time as well as depth sections output could thus be obtained in the end. Consequently, better sensitivities, S/N ratios as well as resolutions were achieved.In this paper, the idea, the basic theory as well as the processing technique about the stacking and migration of seismic refraction were expanded. The results of modelling were given.
