地震检波器抗温变技术研究

Temperature against fluctuation technologies of seismic geophones

目前地震勘探中使用的地震检波器绝大部分是磁电式检波器,磁电式检波器参数随着环境温度改变会产生温变效应。这种温变效应改变检波器工作模态,从而对采集产生影响。文章从检波器工作原理和制造原理入手,提出了具体的解决方案,为研制抗温变检波器提供理论和技术基础。

Currently most geophone used in seismic exploration is magnetelectric type geophones,as environmental temperature changes,the magnet-electric type geophone parameters will produce the temperature change effect.The temperature change effect will change the work modal of geophone,thus influencing acquisition.From the geophone working principle and manufacturing principles,This paper puts forward specific solution,and provides theory and the technology base for the development of temperature-to-resistance change geophones.
