摘要
分析了用于时移地震互均衡处理中的传统匹配滤波算法适用范围,结果表明该方法在滤波算子的反算子为最小相位时效果最好.对该方法难以解决的混合相位问题,推导出通用公式,并提出基于最小平方误差准则和循环迭代的求解方法.理论和实际数据都验证了该方法较已有方法的优越性.
We analyze the application range of conventional matching filter in time-lapse seismic cross-equalization. The result indicates that this method can work very well when the inverse operator of the filter is the minimum phase. Generalized formula is derived for inverse filter with hybrid phase. And the method based on error criteria and iteration is proposed. The effectiveness of the method is tested though theoretical analysis and real data processing and compared with other methods.
