摘要
Sallas,J.J.在2010年的EAGE年会上提出了可控震源低频能力输出的限制条件,这些限制条件一直以来也是可控震源生产厂家对可控震源许用频率定义的一个重要依据。本文主要根据一些有针对性的试验,从可控震源传感器在低频段的响应等方面入手,对低频能力限制条件在可控震源上的反馈信息进行了总结与推定。
At EAGE 2010, Mr. Sallas, J. J. put up the limited factor to low frequency of vibrator which is the important basis of the definition of the low frequency capacity by most of the vibrator manufactures until now. In this paper by means of some experiments the feedback of the linear variable displacement transducer to the mass motion at low fre- quency is raised and summarized.
