摘　　要：受水深、海况、地貌、地质情况等因素的影响,深水地震资料具有"Jitter"现象、子波变形、噪音多样、多次波发育、速度敏感、各向异性显著等特点。系统分析深水地震资料特征,总结深水地震资料规律与差异,分析研究综合静校正、子波精细处理、高保真噪音衰减、组合压制多次波、高精度速度分析、各向异性偏移等关键技术,形成深水地震资料处理流程,在实际资料处理中取得良好效果。As influenced by water depth,sea conditions,topography,geological conditions and other factors,the deep seismic data has some specific characteristics,such as the＂Jitter＂phenomenon,wavelet distortion,diverse noise,multiple wave growth,speed-sensitive,and significant anisotropy.By systemic analysis of the characteristics mentioned above,the authors summarized the common features and differences of the deep seismic data.Various processing techniques were studied,such as the integrated static correction,fine processing of wavelet,high-fidelity noise attenuation,combined suppression of multiple reflections,high-precision velocity analysis,anisotropy offset and other key technologies.A processing flowchart was proposed for the deep-water seismic data.With the integration of the techniques,the quality of seismic data is obviously improved.
