| 摘 要： | 三维地震叠前深度偏移可实现反射点的正确空间归位和真正的共反射点叠加,减小菲涅尔带的影响范围,大大提高地震资料的分辨率。论述了三维地震叠前深度偏移的成像原理和关键技术,并应用于实际地震资料的处理中。结果显示,小断点显示较叠前时间偏移剖面更为清晰,提高了煤田三维地震探测细微构造的能力,取得了较好的地质效果。 |

| Abstract: | In this paper,we discuss the imaging principle and key technology of pre-stack depth-migration in 3D seismic exploration.The 3D pre-stack depth-migration technology may realize the correct spatial homing of the re-flection point and the stacking of the real common-reflection-point,which decreases the extent of the Fresnel zone and greatly improves the resolution of seismic data.In the actual seismic data processing and applications,the breaking points of small faults of this technology are more clearly disp... |
