APPLICATION OF GEOEAST SYSTEM TO PROCESSING OF SEISMIC DATA FROM DEEP-SEA TWO-DIMENSIONAL TOWING
-
摘要: 利用GeoEast系统所具有的软件和地球物理功能优势,使其在海洋二维拖缆资料处理中,能够快速地将单炮数据进行解编和观测系统加载。消除低频涌浪噪音及压制多次波是海洋地震资料处理的难点。异常振幅衰减技术对于消除涌浪噪音效果较好。然而,针对本区多次波发育的特征,选取了SRME、Radon变换组合方法压制多次波,实际证明压制效果明显。Abstract: The GeoEast software and its advanced geophysical functions were adopted in the processing of marine seismic data from two-dimensional towing. Single-shot seismic data could be decoded and the geometry could be loaded quickly. Removing the surge noise and multiple wave is a difficult job in marine seismic data processing. It is effective in our practice to remove the surge noise by depressing anomalous amplitude. And according to the characters of the multiple reflection wave in this region, we selected SRME and Radon transformation to suppress multiples effectively.
