| 摘 要： | 衰减近道多次波、剩余多次波的解释一直是地震资料处理中的难题。应用智能引导滤波技术(Leading Intelligence Filter Technology,简称LIFT)可以解决该问题。LIFT技术的原理是进行信噪分离,在去除的噪音信号中再提取非常微弱的有效信号,然后进行数据重构,以达到衰减噪音的目的。通过对东海陆架盆地南部二维某测线地震资料进行处理,证明使用该技术可以衰减近道多次波并同时保持道集完整性,可以解决剩余多次波在偏移成像剖面上造成的构造假象问题。

| Abstract: | To suppress the near offset multiples and residual multiples is difficult in seismic data processing.The LIFT(Leading Intelligence Filter Technology) is an approach that can extract the weak effective signal from the attenuated noises and reconstruct the seismic data.The processed example indicates the LIFT not only can be used to suppress effectively the near offset multiples and residual multiples but also can improve seismic image. |
