【摘要】 常规地震勘探检波器接收的是纵波的信息,只有一个分量,是标量接收系统;三分量检波器接收的是三个分量的信息,是矢量接收系统。矢量接收系统必然存在矢量保真的问题,因此当三分量检波器埋置倾斜或方位存在误差时,将直接影响到采集资料的品质。本文以Vectorseis三分量检波器为例,分析了三分量检波器的矢量保真问题,探讨了野外检波器埋置对矢量保真质量的影响以及控制保真质量的方法。更多还原

【Abstract】 The common geophone is usually a scalar receiver system only receiving one component information P-wave.But the three-component geophone is a vector system,can receive not only the information of P-wave,but also the C-wave.Since Vector receiving system may be bound to fidelity issues,so when the three-component geophone buried tilt or azimuth error exists,it will directly affect the quality of collected data.This paper takes Vectorseis three-component geophone as an example,analyzes the problems about vector-fidelity then provides methods for quality control about the fidelity.更多还原
