从地震资料中提取频率信息在岩性分析上有广泛的用途。目前,一些提取频率信息的工作通常在大计算机上进行。为了适应生产实际的需要,南阳油田地调计算站使用TQ-16小型计算机,研制成功四种提取和显示频率信息的程序:连续频谱图可提供某炮、某道、某段的频谱分析图件,也可提供相邻道、炮,或在一固定的时窗内沿一个目的层连续追踪频谱的变化。平均加权频率-时间图像它能把频率信息附加在地震记录的波形之中,频率的等级用颜色的浓淡表示,现有五个等级。频率-时间剖面它可在不同颜色的背景上描绘地震波形,兼有通常的时间剖面和特加
Extracting frequency information from seismic data has a wide range of uses in lithology analysis. At present, some work of extracting frequency information is usually performed on a large computer. In order to meet the practical needs of production, Nanyang Oilfield Geographic Computing Station using TQ-16 small computer, developed four successful extraction and display of frequency information procedures: continuous spectrum can provide a gun, a road, a section of spectrum analysis map , But also to provide adjacent tracks, guns, or continuously track changes in the spectrum along a target layer within a fixed time window. Average weighted frequency - time image It can be frequency information attached to the waveform of the seismogram, the level of the frequency of color shades, there are five levels. Frequency-Time Profile It depicts the seismic waveforms on different colored backgrounds, with both common time profiles and special effects
