摘要
仪器操作员在使用G3i仪器与Vib Pro电控箱体进行可控震源施工中的质量控制基本依靠PSS报告。相位指标如果过大,将直接影响原始数据进行相关运算的准确性,故在生产中仅依靠PSS报告中的数字指标进行质量控制是不够的。相位指标的计算方法、超标标志、超标原因、校正方法等都需要技术人员熟悉掌握。本文从仪器操作员日常应用的角度介绍了可控震源质量控制中相位指标的原理分析和控制要点。
Working with G3i Vib Pro acquisition system and Vib Pro control box, the observers depends on the PSS report for quota data and quality control. But if the quota data were far away from controlling limits, it will directly influence the original data and, sure, influence the accuracy of correlation progress. Thus for the observers, they must be very familiar with the calculation method of the phase index, the standard mark, the cause of exceeding, the correction method and so on. Based on the observer＇s daily operation, this paper simplifying introduced the principle of vibroseis phase control and key points managed.
