海洋地质综合研究大队计算站

本文在地震道复数道分析的理论基础上,介绍了复数道计算的一种方法,提出了解释层位上平均能量谱、平均频率谱及峰-谷宽度剖面的制作方法。并应用类似于光谱分析的显示方法,显示了上述几种计算结果。还采用了彩色叠合显示手段将触释层位上的能谱剖面与地震剖面用不同色彩叠合显示于一张剖面上,因而十分利于地震资料的岩性解释工作。

Based on the complex trace analysis, the ways of calculating the three instantaneous modules were presented. The techniques of calculating the average energy and frequency spectrum as well as the width between the crest and the trough were put forward. Results were displayed by the techniques as those adopted in optical spectrum analysis. Besides, the average energy spectrum of the horizon being interpreted and the seismic traces could be displayed on the same section by the colour-overlapping display, so, the technique recommended is actually very favourable to the interpretation of lithology.
