摘要： 在地表复杂地区采用 一种震源激发获取三维地震资料,存在较大的困难。如果使用不同震源,要求在处理过程中,消除不同震源地震资料在振幅、频率、相位方面的差异。经研究提出了一种在不同震源激发条件下,三维地震资料的拼接处理方法:求解一个震源转换因子并应用到一种震源的地震资料中,将该震源的地震资料转换为另一种震源的地震资料。实际地震资料处理表明,该方法对具有一-定信噪比的不同震源三维地震资料的拼接处理是很有效的。

Abstract: It is normally difficult to receive 3D seismic data by using one vibrator in complex surface area. When adopting different vibrators, the seismic data processing from them has to concern about elimination of the differences among amplitude, frequency and phase. This study proposed a method for split processing of 3D seismic data in the condition of different vibrators, that is, resolving a conversion factor of one vibrator, using it into seismic data from one vibrator, and then converting the seismic data into data from another vibrator. The real data processing indicates that this method is very effective for 3D seismic data split processing of different vibrators with certain signal-to-noise ratio.
