地震勘探中振动问题分析
|
摘要
地震勘探中的激发和接收分别是产生振动和感应振动的过程 ,因此地震勘探中振动问题的研究就是从根本上研究激发接收技术 ,这将有助于提高地震勘探的技术水平。分析了激发产生振动的过程、震源的耦合谐振特点和接收感应振动的过程、检波器的耦合谐振问题 ,分析了近地表振动系统产生的振动干扰。这些分析结果对于地震勘探方法研究具有较大的指导作用。
The shooting and receiving in seismic exploration corresponds respectively to the processes of vibration generation and vibration detection. Therefore, the study of vibration problem in seismic exploration is basically the study of excitation and receiving technology that helps to improve the overall level of seismic exploration technology. This paper examines the course of vibration generation and coupling resonance of sources, as well as the course of vibration detection and the coupling resonance of geophones. The interference to vibration caused by near surface vibration system is also discussed. The results will help to guide the method study in seismic exploration.
