由一种统计地震模型发展起来一种对地震资料的加权迭加处理理论。这种模型应用于作了动、静校正的共反射点地震记录及普通的迭加过程。这种模型分别对地震记录的信号及噪音分量作了规定:(1)信号与其它记录上的信号有相同的形状;(2)噪音与其它记录上的噪音及信号统计独立,其平均值等于零。根据此模型,用它的信号相对振幅及能量信噪比就可完全地描述用于加权的地震记录。提出了用来估算野外地震资料参数的一些统计方法,并用合成记录及野外地震记录表明了其中最有利的程序。
A statistical stacking model developed by seismic weighted seismic data processing theory. This model is applied to the moving and statically-corrected reflection points of seismic records and ordinary stacking processes. The model defines the signal and noise components of the seismic record respectively: (1) the signal has the same shape as the signal on other records; (2) the noise is independent of the noise and signal statistics on other records and the average value is equal to zero . According to this model, the seismic record for weighting can be completely described by its signal relative amplitude and energy signal-to-noise ratio. Some statistical methods for estimating parameters of field seismic data are proposed. The most favorable procedures are shown by using synthetic records and field seismograms.
