灰色理论在塔中储盖组合解释研究中的应用

采用灰色系统理论新的思维方式，实现塔中地区储盖组合测井解释研究．利用测井、钻井取心、试油及有关地质资料为标准，通过匹配、自动拟合和提取参数，分别以评价参数对精细划分的地层岩性、物性、含油性及盖层质量进行统计，建立起灰色系统理论储盖组合测井解释评价标准、权系数、自动处理方法及分析准则，形成了一套新的有效的储盖组合测井解释软件系统．通过该区５６口井志留、泥盆系及石炭系东河砂岩段储盖层的精细评价和综合解释，计算出不同类型储盖层参数，划分了岩性剖面，并对一、二、三、四类油气储层和盖层作出了评价．介绍了储盖层精细评价解释中的应用实例．

Application of Grey Theory in the Well Logging Interpretation of the Reservoirseal Combination in Central Area of Talimu Basin

Abstract Based on the data from well logging,cores,well testing and geologic information,the statistical analysis of formaiton lithology,physical properties,oilbearing character and capping bed quality are made.The evaluation criterion,weighting coefficient,automatically processing method and analysis criterion are set up based on grey theory for the well logging interpretation of the reservoirseal combination.A practical software system is developed for this purpose.The Silurian,Devonian and Carboniferous Donghe sandstone intervals from 56 wells in this area are processed with the software system.The parameters of different types of reservoir and seals are worked out,lithological profiles are classified,and four types of the oil reservoir and seals(,,,)are evaluated.Carboniferous Donghe sandstone and lower Silurian sandstone are taken as examples in this paper.
