摘要
厚黄土覆盖的丘陵地区,表浅层黄土结构疏松、潜水位深、对地震波吸收强烈,是煤田地震勘探的一大难题。我队在介—平勘探区,通过多种手段进行了攻关研究,采用"两低一深,两大两多,一高及可控"的一套适合这类地区的采集技术和以静校正、叠前面波、线性干扰压制及叠后f-x域去噪为核心的低信噪比资料处理技术,取得了一定成果,具有在类似地区推广使用的价值。
It is quite difficult to perform coalfield seismic exploration in thickloess covered hill areas because of the loose loess structure, strong absorbency to seismic wave and deep water table in these areas. In JiePing areas, the Shaaxi Geological Research Party for Coal Exploration adopted a series of dataacquiring methods and low signaltonoise ratio dataprocessing technique to solve these problems on the basis of deepgoing researches. The technique has been proved to be effective and can be used in other similar areas.
