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。
Deep as a reserve to succeed regional and natural gas exploration is an important area, more and more attention. However, the quality of the deep seismic reflection data is poor, and the target interpretation and lithology prediction are very difficult. In response to this situation, a set of FracDif seismic high-resolution processing software package was compiled, which solved the problem well. Studying the response of seismic parameters caused by the change of sandstone and mudstone, the distribution of deep mudstone in WJT area of Daqing is predicted and good results are obtained.
