北京断陷黄庄—高丽营断层伪随机可控震源地震剖面
|
摘要
位于北京断陷西北边界的黄庄—高丽营断层是区域新构造运动中的一条重要的隐伏断层,本研究利用伪随机可控震源及其高精度反射地震方法,调查了该断层在北京奥林匹克公园段的特征.研究工作首先从理论上分析了可控震源解码原理和抗噪声能力,然后利用三分量波动方程正演指导了黄庄—高丽营断层的野外地震观测,在城市强噪声环境下采集了高精度的地震数据,经过数据处理在该地区第一次得到地震偏移深度剖面.获得的地震偏移深度剖面清晰地显示了黄庄—高丽营断层的位置,地质解释结果为进一步明确剖面上断层两侧新生代地层的厚度提供了依据.
Huangzhuang-Gaoliying fault,located in the northwest edge of Beijing fault depression belt,is an important buried fault in the Quaternary tectonic period.To know the geological characteristics of the fault,high-resolution seismic exploration with Mini-sosie vibrator was conducted.The study focuses on the part of the fault through the Olympic park by using Mini-sosie method and near-surface seismic profile.Three-component wave equation modeling and ray tracing method were implemented to design the geometry and parameters in field data acquisition to meet the requirement for city seismic survey.The decoding principle and the anti-noise capacity of Mini-sosie vibrator were analysed to demonstrate that the Mini-sosie is feasible for the city environment with strong noise.After high-solution data processing,a seismic depth migration section with high-resolution in the strong noise environment in this survey area was obtained.Huangzhuang-Gaoliying fault in the seismic depth migrated section can been seen clearly.The result of geological interpretation clarified the thickness of Cenozoic strata in the two sides of the fault.
