摘要
涡流检波器因具有较好的高频特性等优点,在高分辨率地震勘探中获得推广应用,同时对涡流检波器的精确测量也愈加迫切.文章概述了涡流检波器的工作原理,介绍了有关参数和测量方法.将当前的测量方法分为两类,一类是基于4参数模型辨识的稳健测量,一类是基于7参数模型辨识的精密测量.通过理论分析和实验研究,建立了检波器4参数和7参数的转换关系,综合了二者的优点,提出了一种涡流检波器的稳健精密测量方案.仿真结果显示本文方法可获得更好的测量结果.
Eddy acceleration geophones have been widely used in higher resolution seismic exploration owing to its better performance in high frequency together with other virtues, the accuracy measurement of geophone becomes more and more urgent. In this paper, the principle of the eddy acceleration geophone is summarized, the parameters systems responding to the working principle is introduced. The current measurement methods could be divided into two class, one is the robust measurement based on 4parameter model identification, the other is the precision measurement based on 7-parameter model identification. Combined the theoretic analysis with experiment research. The relationship between 4-parameter model and 7-parameter model is set up, each virtue is integrated, a new measurement scheme is proposed, with which a robust and precision measurement for an eddy acceleration geophone is achieved. It is illustrated by simulation experiment that an even better result can obtain with our method.
