摘　　要：深层作为储量接替地区和天然气勘探的重要领域，日益受到重视。但深层地震反射资料质量较差，目的层的追踪解释及岩性预测都很困难。针对这一情况，编制了一套FracDif地震高分辨率处理软件包，较好地解决了这一问题。研究砂泥岩变化引起的地震参数响应，对大庆WJT地区深层泥岩分布进行了预测，取得较好效果。As an important field of oil reserve succeeding and natural gas exploration, deep strata is paid more and more attention to. But seismic reflection data from deep strata is of poor quality, and it is difficult to trace and interpret target layers as well as predict their lithology. In view of these problems,a high-resolution seismic processing package named FracDif is drawn up. The authors researched on theresponse of seismic parameters to sandstone and mudstone variations and predicted the deep mudstonedistributbo in WJT area, Daqing. A good result has been achieved.
