【摘要】 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.更多还原

【Abstract】 The seismic data processing techniques in deepwater area are different to shallow water.In this paper,several key seismic data processing techniques are discussed and applied in deepwater area of Liwan 3-1 gas field,including deepwater wavelet processing technique,acquisition footprint suppressing technique,3D-SRME inτ-p domain,3D geosteering filter technique,anisotropy PSDM,etc.Seismic imaging is improved apparently.In addition,broad-seismic data acquisition and processing are discussed by variable depth streamer. The processing technique series in deepwater is an important reference for deepwater seismic data processing in other area.更多还原
