地震勘探野外施工中,人们习惯把仪器车内的仪器及相应连线叫内线,把车外的大线、小线、炮线、信号线、井口线、检波器等通称为外线。施工中,在仪器各项技术指标合格的情况下,原始记录上出现感应,多数由外线引起。感应,对地震波产生干扰,严重影响原始资料的质量和施工的进度。对于感应,目前人们还无统一的认识。一般认为,凡不是由于检波器机电转换而得到的记录信号都称为感应。在鉴别原始资料上是否存在感应时,应注意几点:(1)应把感应与地震工作中的各种规则、不规则干扰波相区别;(2)检波器埋置不好,动植物骚动,机
In the field of seismic exploration, people are accustomed to calling the instruments and their corresponding connections inside the instrument vehicle and calling the outside lines such as the large lines, small lines, gun lines, signal lines, wellhead lines, and geophones outside the vehicle. Construction, the instruments in various technical indicators of qualified cases, the original records appear on the induction, the majority caused by the outside. Induction, the earthquake wave interference, seriously affecting the quality of the original data and construction progress. For sensing, people do not yet have a unified understanding. It is generally believed that all recorded signals that are not due to the electromechanical transducers of the detector are called inductances. When identifying whether there is sensing on the original data, several points should be paid attention to: (1) The rules of induction and seismic work should be distinguished from those of irregular interference; (2) The geophone is not well embedded and animal and plant turbulence ,machine
