摘要
428XL-G型仪器是法国SERCEL公司推出的400系列新一代千兆地震勘探仪器系统。2019年3月,笔者首次采用G型主机在XJ沙漠较高海拔地区开展了超多道三维井炮作业施工。施工中发现该型号主机的辅助道会产生随机尖脉冲干扰现象。本文针对这一问题,在现场进行了多种条件下的模拟测试,最终找到了问题,并提出了解决方法。实践证明该方法可有效避免随机尖脉冲干扰对地震采集资料记录质量的影响。
The 428 XL-G type instrument is a new generation of gigabit seismic prospecting instrument system in 400 series produced by SERCEL Company of France.In March 2019,the author used G-type system to carry out ultra multi-channel three-dimensional in the high altitude area of XJ desert for the first time.During the construction,it is found that the auxiliary channel of this type of interference system will produce random sharp pulse.Aiming at this problem,this paper has carried out simulation tests under various conditions in the field,and finally found out the problem and proposed solutions.It has been proved that this method can effectively avoid the influence of random sharp pulse on the quality of seismic data.
