震源平板扰动对地震采集信号的影响

Vibroseis signal distortion caused by baseplate disturbances

在地震资料采集过程中,可控震源激发信号的品质将随着地表的复杂化而发生劣化,并且震源在扫描时间段外平板产生的扰动亦会对采集信号产生不同程度的影响。本文介绍了震源平板升降冲击和平板链条拉紧状态产生扰动对采集信号的影响,分析了扰动产生的原因及注意事项。

In the process of seismic data acquisition, vibroseis signal＇s quality will become worse with the surface environ- ment become more complex. Except the scanning time, disturbance generated from baseplate up-down will also have different influences on the acquisition signal. This paper introduces the effects caused by these disturbances on data acquisition, and also analyzes the causes and notes of these disturbances.
