摘要
本文提出了一种利用常规测井资料进行薄层评价的方法，主要内容包括：运用常规测井分析软件进行处理，得到低分辨率地层物性参数；运用数字信号处理手段划分薄砂层，提高自然伽马曲线的纵向分辨率和深感应曲线的纵向分辨率，求出高分辨率的孔隙度、含水饱和度等物性参数；最后进行综合评价。该方法处理大庆地区数口井测井资料表明，明显优于其它现有的薄层评价方法。
With the development of petroleum industry,evaluation of thin-bed becomes increasing-ly important. The current thin-bed evaluation method is not satisfactory and it can not meetthe needs of petroleum exploration and development.This paper suggests a method withwhich the thin-bed is evaluated with conventional log suites. The method is as follows : firstto process the logs with a common software;second to delineate thin-bed and to improve thevertical resolution GR and conductivity with the digital processing techniques;then to get thehigh resolution porosity,water saturation etc,finally,comprehensive interpretation is made.The method is proved obviously superior to other methods in thin-bed evaluation.
