摘要
在山地地震勘探中,时断信号的准确性是资料采集量化分析和地震记录质量评价的重要方面。基于BOOMBOX数字爆炸机和SSS300模拟爆炸机的原理分析,采用多踪存储示波器对两种爆炸机的钟时断信号、回复验证时断信号和实际验证时断信号进行了监控测试,对验证时断信号准确性影响因素进行了量化分析,研究结果为提高验证时断信号的准确性、正确判断与评价地震记录的质量提供了依据。
For seismic exploration in mountainous areas, the accuracy of time break (TB) signal is vital for the quantitative analysis of seismic data acquisition and quality control of seismic record. Based on the principles of confirmation TB signal generation, clock TB signal, feedback confirmation TB signal, and actual confirmation TB signal were monitored by multiple-trace storage oscilloscope for BOOMBOX digital blaster and SSS300 analog blaster, and quantitative analysis of the factors that affect the accuracy of the confirmation TB signal was carried out. The results can be used for the basis of improving the accuracy of the confirmation TB signal and quality control of seismic records.
