本文提出一种压制地震记录中多次反射的新方法。它是建立在应用全声波方程(双曲线形式)作为向下延拓算子的向下延拓方法基础上的。我们证明记录波场的向下延拓可绘成反射率函数曲线,而没有多次反射波。该方法成功地应用于单道平面波以分解(倾斜叠加)合成记录和野外数据。
This paper presents a new method of suppressing multiple reflections in seismic records. It is based on the application of the total acoustic wave equation (hyperbolic form) as the downward continuation method for downward continuation operators. We show that the downward continuation of the recorded wavefield can be plotted as a function of the reflectivity without multiple reflections. This method has been successfully applied to single-channel plane waves to decompose (obliquely superimpose) synthetic records and field data.
