可控震源及其发展

可控震源输入到大地的信号是己知的,频谱可以人为地改变,因而有可能从激发地震信号方面来改善资料品质。本文从可控震源的性能方面分析了对地震资料品质起限制作用的诸因素及其解决途径;建议开展相应的课题研究和研制新型的可控震源。

Vibroseis and its development

Vibroseis gives the earth controllable signal train whose frequency spectra can be artificially changed,therefore data quality can be improved by controlling the signal excitation of vibroseis.The author approaches both the factors which damage seismic data quality and the solutions to them by analysing the characteristics of vibroseis.It is suggested that the corresponding theoretical study should be made and new vibroseis developed.
