摘要
我国于2008年至2012年开展"深部探测技术与实验研究专项(SinoProbe)",其中大地电磁参数标准网是该计划的重要组成部分,大地电磁参数标准网建设需要大量的高质量的观测数据,本文分析了国内外主流的大地电磁仪器设备,野外数据观测方法和资料处理技术手段,并简述了西北区域大地电磁网建设方法。在此基础上,对新疆石河子地区45-86标准点进行了野外观测,对采集的宽频数据和长周期数据进行了深入的处理,新疆地区该标准点噪声干扰较小,野外观测数据质量较高。形成了大地电磁标准点建设中辅助观测站与中心主观测站布置、数据采集方法与时间和资料处理技术手段等一套流程规范,为后续标准点的建设提供了一个参考样本。
The special SinoProbe ＂deep-earth exploration techniques and experimental study＂ has been carried out in China in 2008-2012 and an important part of this project is the establishment of MT parameters standard network,which needs high-quality field observation data.This paper has analyzed the domestic and international mainstream magnetotelluric equipment,field data observation method and data processing technique,and described how to construct magnetotelluric network in the Northwest Region.Based on this,we have conducted field observations of 45-86 standard points in the Shihezi region and further processed the acquired broadband data and long-period data.Because little noise lies in the standard point of the Xinjiang region,field observation data has higher quality.What＇s more,the standard process from the distribution of the main and secondary observation stations to data acquisition method and data processing technique provides a reference sample for the future construction.
