|
摘要
针对富县黄土塬地区地震资料信噪比低、静校正问题严重的特点,开展了地表一致性处理技术、静校正技术、串联去噪技术、高精度速度分析及地震成像方法等技术的研究,总结出了一套适合于该区地质特点的地震资料处理方法与流程。通过对实际资料的处理和应用,效果明显,从而证明了该技术的实用性和可靠性。
Aiming at the characteristics of low signal to noise ratio and serious statics problem in loess covered area of Fuxian,techniques were studied such as surface consistent processing technique,static correction technique,serial noise attenuation technique,high precision velocity analysis and seismic imaging methods and so on.A set of seismic data processing approach and processing sequence was summarized which was suitable for the geological feature in this area.Through the processing and application of real data,the effect was obvious so as to verify the practicability and reliability of the aforementioned techniques.
