摘　　要：本文论述了提高迭后地震记录分辨率的频率振幅补偿方法原理及实际应用效果。该方法利用了最大方差模原理，使地震信号的修正方差模达到极大，迭代计算补偿地震记录的高频成份，并对其补偿后的地震记录振幅谱给予加权标定，使之逼近于资料实际反射系数振幅谱，从而达到提高地震记录分辨薄层的能力。This paper introduces a frequency-amplitude compensation method which can improve the resolution of stacked seismic data and analyze its implication. Based on the maximum variance norm, the method adjusts the variance norm to maximum, and, by iterative computation of the high frequency of seismic data and through the amplitude spectra weighting, approaches it to the amplitude spectra of actual reflection coefficients, and thus improves the thin-bed resolution of seismic data.
