【摘要】 高密度数字检波器资料处理的目标是提高分辨率高与信噪比。针对分辨率与信噪比这一对矛盾,可通过多种手段在多域进行叠前去噪处理实现;依据数字检波器的单点采集方式,为降低野外组合对高频信号的衰减,采用室内组合技术,提高资料信噪比;对于单点高密度数字资料中的强面波干扰,则在十字排列域中使用三维锥形滤波法。通过对淮南某矿区的单点高密度数字资料处理的实例表明,采用上述技术得到的叠加剖面,与常规模拟检波器资料相比,具有更高的成像精度。更多还原

【Abstract】 Data from high density digital geophone have characteristics of high resolution, low signal-noise ratio. For the better resolution and S/N ratio, it carries out prestack denoising using multiple means in multiple domains. In allusion to single-point acquisition mode of digital geophone, to avoid field assemblage attenuation of high frequency signals, uses indoor grouping technology improved data S/N ratio. To single-point high density digital data strong ground wave interference, uses 3D tapering filter in X-spread domain. A coalmine district single-point high density digital data processing case study has shown that the stacked sections from above mentioned technologies have higher imaging precision compared to traditional analog geophone data.更多还原
