海洋深水区地震资料的处理有其自身特点.以荔湾3-1气田为例,探讨了深水区地震资料处理中的几项重要技术,包括深水子波处理技术、采集脚印衰减技术、τ-p域3D-SRME多次波压制技术、三维地质导向滤波技术、各向异性叠前深度偏移技术等,展示了各项技术在本区的应用效果.同时分析了本区倾斜缆地震资料的采集和处理情况.总结出了针对深水区地震资料的处理技术系列,对其它深水区地震资料处理具有重要的参考价值.
Seismic data processing in deepwater ocean has its own characteristics.Taking Liwan 3-1 gas field as an example, several important techniques in seismic data processing of deepwater area are discussed, including deepwater wavelet processing technique, acquisition footprint attenuation technique, τ-p Domain 3D-SRME multi-pressure suppression technology, three-dimensional geo-directional filtering technology and anisotropic prestack depth migration technology, etc. The application results of various technologies in this area are also demonstrated.Seismic data acquisition And deal with the situation.The paper summarizes the series of processing technology for the seismic data in the deepwater area and has important reference value for the seismic data processing in other deepwater areas.
