优化高频拓展法在煤田勘探中的应用
Application of Optimized High-Frequency Expanding Technique in Coalfield Exploration
【摘要】 提高分辨率是地震数据处理中获得高质量资料的关键,而分辨率与信噪比的相互制约关系是高分辨率处理的根本问题。优化高频拓展技术在提高分辨率的同时基本保持地震数据原有的信噪比,并且可以保持地震数据相对振幅关系和时频特性,做到真正的保真处理,为精细薄互煤层分析提供可信的高质量地震数据。
【Abstract】 Resolution improving is the key to obtain high quality results in seismic data processing.The interaction between resolution and SNR is the basic importance in high-frequency processing.The optimized high-frequency expanding technique can basically possess of seismic data original SNR,relative amplitude relation and time-frequency characteristics during the resolution improving.Thus,unadulterated fidelity processing can be accomplished for high quality seismic data to accurate analyzing of thin and alternating beds of coal seams.
