在可控震源地震勘探野外施工过程中,不同的地质条件需要设置不同的激发参数,如何选择合适的激发参数便成了野外施工所必须关注的问题.笔者介绍了可控震源的震源台数、扫频大小、振动次数、扫描长度、扫描斜坡、振动幅度参数对地震记录质量的影响,并通过在九里山的激发试验,研究如何正确选择激发参数,以最大限度地提高可控震源地震勘探分辨率及地震记录的信噪比.

Vibroseis exploration, as an important method of seismic exploration, has become increasingly valued by geologists. During the field work, different geological conditions need different parameters, and the choice of suitable excitation parameters has become a very important problem. This paper mainly introduces six kinds of parameters, namely numbers of controlled seismic source, scanning bandwidth, vibration period, scanning length, scanning slopes, and vibration rate. The influence of these parameters on the quality of seismic records was studied in detail, and the simulation of the proper parameters was performed in Jiulishan area to enhance the resolution of vibroseis exploration and improve the signal-to-noise ratio of seismic records.
