摘　　要：文章对圈闭评价和模糊数学的基本概念进行了介绍 ,详细地阐述了模糊数学在圈闭评价中的应用机理。在建立四川盆地部分已钻石炭系圈闭模糊评价样本的基础上对渝东地区石炭系圈闭进行了模糊评价 ,根据模糊评价结果优选出寨沟湾、复兴场、建南、中台子等为研究区最有利圈闭。同时模糊评价结论和渝东地区石炭系圈闭勘探结果是比较吻合的 ,这说明用模糊数学方法对渝东地区石炭系圈闭所进行的评价结论符合客观实际。In the paper, the basic concepts of trap evaluation and fuzzy mathematics are introduced and the mechanism of applying fuzzy mathematics to trap evaluation is expounded in detail. On the basis of setting up the specimen copy of fuzzy evaluation of partial Carboniferous traps drilled in Sichuan Basin, the fuzzy evaluation of the Carboniferous traps in East Chongqing was carried out and according to the evaluation results, the Zhaigouwan, Fuxingchang, Jiannan and Zhongtaizi traps were selected as the most beneficial traps in this area. In addition, the fuzzy evaluation conclusion is relatively tallied with the exploration result of the Carboniferous traps in East Chongqing, which indicates that the conclusion of evaluating the Carboniferous traps in East Chongqing by use of fuzzy mathematics is in keeping with the objective reality.
