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。
Shandong Energy Zibo Mining Group Corporation Tangkou Mine westen F area was provided with complex structure, plenty of large fauh, fold development, large coal seam inchnation, 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.
