F-X-Y域全三维预测去噪

A Method of Restraining Stochastic Noise in Signal Prediction

基于地震反射信号在空间-频率或存在线性预测关系这一事实,可导出F-X-Y域全三维预测去噪方法。在三维地震资料处理中,这是校理想的一种叠后随机噪声衰减技术。由于在信号估计中充分利用了全三维信息,与二维方法相比,信号估计精度更高,噪声衰减能力增强。本文较详细地推导了方法原理,给出程序实现步骤,并展示了理论试算与实际资料处理结果。

According to the seismic reflected signal has linear relationship in space-frequency, a method of restraining stochastic noise is got. In 3D seismic data processing, this is ideal method on post slack data. Compared with the 2D method, function of restraining noise is more strong, precision of prediction more high. This paper gives principle of method, program and shows theoretical and actual results.
