【摘要】 山东唐口煤业公司F区西部构造复杂,大断层多、褶曲发育,煤层倾角大,煤层上部有巨厚岩浆岩屏蔽,煤层埋深变化大。采用常规的三维叠后偏移技术处理,虽然能反映该区的整体面貌,但成像效果不佳,难以满足需要。利用克希霍夫叠前时间偏移技术对三维地震资料进行处理,对比分析显示:叠前偏移成果在构造信息和能量信息上均优于常规处理结果,经叠前偏移处理后的数据体,断层成像清晰,归位准确,地质形态更细致可靠。更多还原

【Abstract】 Shandong Energy Zibo Mining Group Corporation Tangkou Mine westen F area was provided with complex structure,plenty of large fault,fold development,large coal seam inclination,tremendously thick magmatic rock shielding on coal seam and large variaration of coal seam depth placing.Normal three-dimensional post-stack immigration was conducted,though whole visage of this area was reflected,the imaging effect was not good and cannot meet needs. Kirchhoff pre-stack time immigration was applied to conduct three-dimensional seismic data.Contrasive analysis showed that pre-stack time immigration achievement preceded normal treatment in construction and energy information.Data volume conducted by pre-stack time immigration got clear imaging fault,accurate homing,reliable and meticulous geology form.更多还原
