摘要

石油地震勘探仪器是实施地震数据采集的核心装备,通常为了匹配输入地震信号的振幅和频率,需在地震仪器中设置一系列的工作因素。在这些工作因素当中,就对地震信号的作用而言,前放增益、采样间隔应该是最为关键的采集因素。本文从地震仪器采集因素的物理意义、主要作用及其对地震信号的作用等几个方面入手,系统地讨论了地震仪器采集因素与地震仪器工作效果之间的关系以及采集因素的一般选择原则和方法,以便为更有效地发挥地震仪器的应有作用提供参考。
Seismic prospecting instrument is core equipment for seismic data acquisition. In order to match amplitude and frequency characteristics of the input seismic signals, a set of working parameters are set. Among the parameters the sample interval and pre-amplifier gain are the most important ones. In this paper several important aspects, such as the physical meaning of the seismic instrument acquisition parameters, main functions, and their impacts on seismic signals, were studied first, then the relationship between seismic instrument acquisition parameters and seismic instrument operation performance, and the selection principles and methods of the seismic data acquisition were systematically discussed, as a result the reference can be provided for more efficient use of the seismic acquisition instrument.
