| 摘 要： | 南黄海前古近系油气储层时代老、埋藏深,地震勘探中仍存在反射能量弱、信噪比低和成像质量差等难题。在分析目标层岩石地球物理特征和地震、地质条件及地震反射机制基础上,提出了南黄海前古近系油气地震勘探策略;在地震数据采集中,应在海况较好的条件采用长排列、高覆盖次数和较大容量气枪震源施工;数据处理的重点应为多次波消除、噪音衰减、速度分析和成像,针对深层弱反射信号的处理难题,建议采用叠前时间偏移和共反射面元叠加等先进的处理技术。

| Abstract: | Pre-Tertiary oil reservoirs in the South Yellow Sea are old and deeply buried, and there are some difficult problems to be solved in the seismic explorations such as weak reflection energy, low signal-to-noise ratio and poor imaging quality. The authors suggested strategy of seismic explorations for pre-Tertiary oil and gas in the South Yellow Sea and thought that during seismic data collection, long spread, high-folding and gas gun seismic source of large capacity should be used in good sea situations, and for data processing, emphasis should be put on pre-time migration,common reflection surface stacking method, noise, velocity analysis and imaging. |
