摘　　要：可控震源在施工中会产生各种类型的噪声,这些噪声也包含震源本身机械运动产生的额外噪声,噪声会在地震记录中产生干扰信号,降低信号的信噪比。这不仅影响地震勘探的数据质量,还影响液压系统的可靠性和稳定性,导致系统设备的损坏。文章从液压系统设计的角度,分析了可控震源液压系统产生嗓声的原因,对主要的噪声来源提出了相应的降噪措施,再对几种常见的降噪方法进行了对比分析,为研究液压系统降噪问题提供参考依据。文章对可控震源液压系统的元件所产生噪声的原因做了分析,简要阐述了可控震源运行时出现噪声时的解决方案。The vibroseis will produce various types of noise during construction,which also includes the additional noise generated by the mechanical movement of the source itself,which will produce interference signals in the seismic record and reduce the signal-to-noise ratio of the signal.This not only affects the quality of geological exploration data,but also affects the reliability and stability of the hydraulic system,resulting in damage to the system equipment.From the angle of hydraulic system design,this paper analyzes the cause of the noise produced by vibroseis hydraulic system,puts forward the corresponding noise reduction measures for the main noise sources,and compares several common noise reduction methods to provide reference for the research of noise reduction of hydraulic system.This paper analyzes the cause of the noise produced by the components of the vibroseis hydraulic system,and briefly expounds the solution when the noise occurs during the operation of the vibroseis.
