摘要
地震仪器的系统同步性能直接决定着地震数据的准确性,当有线系统和节点系统等不同类型、不同厂家的仪器混合施工时,这种情况表现得尤为突出。在掌握不同仪器同步原理的基础上,评估同步性能对地震资料的影响程度是进行混合施工的基础。本文主要分析了428XL仪器的采集触发原理和同步性能。
The system synchronization performance of seismograph directly determines the accuracy of seismic data.This case is particularly prominent when doing hybrid operation by using cable system and node systemwhich are different types ormade by different manufacturers.On the basis of understanding the synchronization principle of different instruments, evaluating the influence of synchronization performance on seismic data is the basis of hybrid operation.This paper mainly analyzes the acquisition trigger principle and synchronization performance of 428 XL instrument.
