| 摘 要： | 在野外地震数据采集参数试验中,激发因素的选择主要通过分频扫描、能量、信噪比或频谱等单一因素的定性或定量分析来实现,但这种分析的结论往往因人而异。本文基于同一震点激发、同排列接收、不同炮激发子波相位相同的假设,利用相关原理,对试验点不同激发因素获得的地震数据进行相关分析,再依据相关系数和叠加相关系数的大小,判别、确定最佳激发因素。文章最后给出的应用实例验证了该方法的应用效果。

| Abstract: | During parameter tests for seismic data acquisition in the field,source parameters determination are made mainly through qualitative & quantitative analyses to frequency scan,energy,signal to noise ratio or frequency spectrum.Analysis results are often different because of different analyzers.The paper discusses parameter optimizing on the following assumptions: with repeated shootings at the same position,receiving with the same spread and same wavelet phase of different shots,and adopting correlation theo... |
