在地震勘探中,组合检波对压制干扰波突山有效波有明显的效果。近一、二十年来,地震勘探尽管在野外施工技术、仪器和资料处理等方面有了飞速发展,但组合检波却不是越来越简单,而是越来越复杂了。其根本原因在于,组合检波仍然是提高讯噪比的主要手段之一。多次迭加代替不了组合检波。今后,在构造复杂,干扰严重地区的工作中,检波器的组合个数、组合形式将越来越复杂。这里有一个突出的问题:大量的检波器组合,检波器之间应该怎样连接?不同连接方式对检波器性能有什么影响?本文就这个问题提出一些肤浅的看法。
In seismic exploration, the combination of detection of interference wave interference effect of the mountain waves have a significant effect. In the past one or two decades, despite the rapid development of seismic exploration in the field of construction technology, instruments and data processing, the combination detection is not simpler and more complicated. The fundamental reason is that combined detection is still one of the main means to improve the signal-noise ratio. Multiple superimposed can not replace the combination of detection. In the future, in the construction of complicated and serious interference areas, the combination of geophones will be more and more complex. Here is a prominent issue: a large number of detector combinations, the detector should be how to connect? Different connections on the performance of the detector What is the impact? This paper put forward some superficial views on this issue.
