Abstract: With the development of petroleum industry,evaluation of thin-bed becomes increasingly impartant.The current thin-bed evaluation method is nat satisfactory and it can not meet the needs of petroleum exploration and development.This paper suggests a method with which the thin-bed is evaluated with conventional log suites.The method is as follows:first to process the logs with a common software;second to delineate thin-bed and to improve the vertical resoluti+n (TR and conductivity with the digital processing techniques;then to get the high resolution porosity,water saturation etc,finally.camprehensive interpretation is made.The method is proved obviously superior to other methods in thin-bed evaluation.

Key words: log interpretation, thin-hed, resolution, deconvolution, filtering

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.
