本文提出了陆上地震资料与地表相关的多次波能量估算和后续消除的三种方法。它们可用于叠前波型(炮点和共中心点道集)或叠后波型中。多次波衰减算法是基于以数据作为算子的波动原理。这样,估算的多次波就可从输入数据中减去,从而得到原始数据。应用多次波消除之前的处理步骤是这些方法中的一个重要部分,特别是在叠前分析中。其目的是使数据规则化,和改善S/N比,均衡地震振幅。这样就会产生平滑预测算子。在多次波压制中,这些方法的有效性通过大量的含有处理陆上地震资料的史例来得到论证。
In this paper, we propose three methods for the estimation and subsequent elimination of multiple seismic energy associated with land-based seismic data. They can be used in prestack waveforms (shot and center point gathers) or in poststack waveforms. The multiple attenuation algorithm is based on the data fluctuation principle as an operator. In this way, the estimated multiples can be subtracted from the input data to get the raw data. The application of multipath cancellation prior to processing steps is an important part of these methods, especially in prestack analysis. The goal is to regularize the data and improve the S / N ratio to equalize the seismic amplitude. This will produce a smooth prediction operator. In multiples suppression, the effectiveness of these methods is demonstrated by the large number of cases that contain data on land-based seismic processes.
