两种井炮激发类型在节点仪器施工中的对比

Comparison of two types of dynamite in node instrument operation

随着长庆探区三维地震勘探项目规模越来越大,节点仪器施工成为趋势。节点仪器施工需要授时分割数据,使用单纯的ShotProII编码器激发已无法实现授时。本文介绍了在节点仪器施工中两种井炮激发类型的授时方式,利用VibPro编码器外置GPS授时和Pro PakV3授时器给仪器主机授时。本文就两种井炮激发类型在软硬件方面做一对比。

With the increasing scale of 3 D seismic exploration projects in Changqing area,node instruments have become a trend.Due to the time division data needed in the operation of node instrument,the time service cannot be realized by using the si mple ShotProII encoder.This paper introduces two kinds of time service methods of dynamite types in the operation of node instrument,using the external GPS timing of VibPro encoder and the time service of ProPakV3 timing system to the main machine of the instrument.This paper makes a comparison between the two kinds of dynamite types in terms of software and hardware.
