摘　　要：以开发测井、钻井取心、试油及油田开发动态资料为标准 ,提出了灰色系统理论高含水期油田水淹层测井解释评价标准、权系数、自动处理方法及分析准则 ,建立了一套高含水期油田水淹层评价解释的软件系统。通过中原油田文 33块沙二下亚段 2 0多口井的水淹层测井解释 ,结合沉积微相及储层研究 ,对油藏水淹状况进行了分析 ,指出了当前生产的主力层位及综合治理的挖潜对象 。Evaluation criterion,weightcoefficient,automatic processing method and analysis criterion for waterflooded formation are given by integrating development well logging data, core data,well testing data and development performance data.Besides,a software system for waterflooded formation evaluation and interpretation at high- cut stage has been setup. The method is successfully used for fine evaluation from more than 2 0 wells in the lower Es2 member in block Wen- 33,Zhongyuan oilfield,field examples of evaluation and interpretation of wateflooded formation at high water cut stage are introduced.Based on above all,the paper analyzed the waterflooded status of the block Wen33reservoir.
