摘　　要：采用未确知测度理论、变权理论和改进的集对分析方法建立盐岩储气库建腔期稳定性评价体系,根据影响因素的等级范围计算指标隶属度,结合据实际情况进行修正的指标权重计算综合测度评价向量,利用集对分析方法定量地给出稳定性等级,分析评价体系状态变化趋势,并以金坛某储气库为例进行稳定性等级划分,结果表明:评价结果与实际吻合度较高。The unascertained measure theory,entropy method and improved set pair analysis method are used to establish the stability evaluation system of salt rock gas storage.The degree of membership of indicator can be calculated according to the level range of the influencing factors and the comprehensive measuring evaluation vector be calculated according to the weights of the indicators modified based on the actual situation.The set pair analysis method is applied to quantitatively give the level of stability and analyze the change trends of evaluation system status.One gas storage in Jintan is taken as an example to conduct the classification of stability level and the evaluation result is in good agreement with the actual situation.
