三维深水崎岖海底区低信噪比地震资料处理策略
|
摘要
深水崎岖海底地震资料处理存在诸多难题,如延续相位问题、噪声与多次波压制问题、成像问题以及长偏移距表现的各向异性问题等等。通过某三维工区深水崎岖海底地震资料处理,探讨了深水崎岖海底低信噪比地震资料的特点及针对性处理策略,分析总结了多域去噪的保幅压噪、多次波衰减、确定性子波反褶积、高密度双谱自动速度分析、弯曲射线偏移等技术及其处理效果,为类似工区的地震资料处理提供了很好的借鉴。
Various problems may occur in the processing of seismic data from deep water bumpy sea bottom area,such as accompanying and secondary events,noises and multiples,imaging,and anisotropy resulted from long offset. This article discusses the characters of low S/N seismic data from deep water bumpy sea bottom area and the data processing strategy. Results from amplitude-preserving noise reduction,multiple attenuation,deconvolution with deterministic wavelet,automatic high-density bi-spectrum velocity analysis,and bending-ray migration were presented and analyzed.
