摘要: 应用突变理论和模糊数学相结合的方法产生突变模糊隶属度函数, 并由此建立CO2 混相驱油藏综合评价模型。该模型首先建立CO2 混相驱油藏指标体系结构, 并对油藏参数进行归一化处理; 然后应用突变模糊隶属度函数法, 对CO2 混相驱油藏进行综合评价和筛选。该模型避免了模糊评价、因子分析及层次分析等方法的弱点, 减少了主观性又不失科学性, 对注CO2 混相驱油藏的筛选具有指导意义。

Abstract: A new assessment method combined catastrophe theory and fuzzy mathematics is established and applied for the first time to evaluate and select the candidate of CO2 miscible flooding reservoirs. Based on the subordinate functions in it, the comprehensive values of all candidate reservoirs are calculated. Case study shows that the results evaluated by such a method is accordant with other evaluation methods, ensuring the veracity and creditability of the results and avoiding the randomicity and troubling of hierarchy process, factor analysis, fuzzy comprehensive appraisal and other assessment methods.

Key words: CO2, miscible flooding, catastrophe theory, fuzzy mathematics, subordinate function
