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.
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.
