摘要

地震数据采集系统的带道能力,也就是最大采集接收道数,是一个反映地震仪器硬件性能的重要指标。本文分析了408XL仪器实时采集道数受限制的原因,提出了在可控震源施工中仪器最大接收道数的计算方法及根据施工设计中采集道数和仪器带道容量确定仪器硬件配置的方法,对可控震源施工中观测系统设计、排列连接、仪器设备硬件配置具有借鉴和指导意义。
Channel capacity,which is the largest channel number to receive seismic data,is an important indicator of the hardware performance of seismic instruments.At first,this paper analyzes the reasons for restricted channels of 408XL instrument during real-time data acquisition.Then,this paper introduces the way about how to calculate the maximum channel number of seismic instrument for seismic exploration with vibroseis operation.Finally the authors propose a method to determine the hardware configuration based on the channel capacity of instrument and the construction design.This method proved to be beneficial to observing system design,array arrangement and hardware configuration of seismic instruments.
