摘要: 本文应用模糊分析设计优选理论与模型评价同类别储层,这种方法根据隶属度的大小,确定同类别储层的若干岩样的相对优劣次序,较为细致地刻划储层的非均质性。文中给出了评价方法的主要步骤,用该方法对川东地区沙罐坪碳酸盐岩储层进行了评价,效果良好。

Abstract: The optimun selecting theory and model for Fuzzy dcsign is applied to appraise reservoirs in a same class. The relative sequence of core samples from reservoirs in a same class are determined in accordance with their values of membership, resulting in more detailed description of reservoir heterogeneities. The major procedure of the appraisal method is presentes in the paper. The result is encouraging when it is appilied to the Shaguanping carbonate reservoir,East Sichuan.
