地震勘探中检波器组合特性研究
|
摘要
本文基于组合的基本原理和方法,分析了两种情况下检波器组合问题.以前在这方面做的研究分析工作很少,但实际上它对地震资料的分辨率影响很大.通过模型计算,从组合后的频率特性曲线上,可以看出在不同的地形条件下,检波器组合个数、检波器间距对地震资料质量和分辨率以及精度有很大的影响.
Based on the theory and method of geophone array,we analyze the question of geophone array under two conditions.Previous researches are little on this issue,but in fact,it affects greatly the resolution of seismic data. Through the calculation of the model,we find that the number and spacing of the geophone array under different ground conditions impose large effect on the quality and resolution and precision of seismic data seen from the frequency curves.
