摘要
通过对国内外各种检波器的类型及型号 ,从工作原理、工作目标、工作对象和工作特点等几个方面进行系统的分析 ,对各类检波器影响地震勘探精度的因素进行归纳 ,对检波器今后的发展方向 ,提出了明确的看法。常规动圈式检波器还会在降低失真 ,减小参数误差 ,消除假频和提高可靠性方面继续发展。但突破动圈式检波器工作原理的光纤数字检波器 。
This paper reviews various seismic geophones made in China and abroad from aspects of operational principles, objectives, and working features. By analyzing factors on each type of geophone that affects acquisition precision, the author discussed the development trend of seismic geophones. Conventional moving coil geophones will still make progresses in reducing distortion, decreasing errors in parameters, eliminating aliasing, and improving reliability, whereas digital optic fiber geophones that are not restricted by the operational principle of moving coils will certainly inject new vigor into the exploration technology.
