摘　　要：地震仪作为地球物理勘探开发的专用核心设备,应用于地球物理勘探开发过程中地震信息的记录和采集,其性能的好坏直接影响监测结果的可靠性。近60年来随着数字电路和计算机技术的发展,地震勘探仪器已经从最初的光点记录发展到当下的全数字遥测记录,地震仪的性能在不断提升,同时随着资源勘探需求、地球科学研究、地下深部空间等不同目标、不同比例尺的探测方法而不断发展。本文通过内蒙古大青山短周期密集台阵野外地震数据采集观测项目,列举了几款常见的短周期地震仪,对比了相关工作参数,整理了地震仪野外采集工作方法,对提高采样数据质量,为下一步数据分析提供可靠保障。As a special core equipment for geophysical exploration and development,seismic instrument is used to record and collect seismic information in the process of geophysical exploration and development.Its performance directly affects the reliability of monitoring results.For nearly 60 years with the development of the digital circuit and computer technology,the seismic exploration instrument has developed from the initial points record to today s digital telemetry,the performance of the seismograph has improved at the same time as the exploration requirements,earth science research and other different goals,such as underground deep space detection methods in different scale and continuous development.This paper lists several common short-period seismographs through the field seismic data collection and observation project of daqingshan short-period intensive array in Inner Mongolia,compares the relevant working parameters,and sorts out the field seismic data collection methods,so as to improve the sampling data quality and provide reliable guarantee for the following data analysis.
