Considering that the stability influencing factors of the salt rock gas storage during the operation period are complex, using analytic hierarchy process, the salt rock gas storage's stability evaluation index system during the operation period is established.based on the indexes' weight distribution and judgment matrix, combining with the application of the grey correlation analysis theory, the stability grey correlation evaluation model of the gas storage during the operation period is established.Combining the indexs' correlation coefficients and weights, taking the correlation degree as quantitative indexs, the gas sto rage's stability during the operation period is analy.ed and compared.With practical engineering examples, this evaluation model is applied to three operating gas storages, the result shows that it accords to the numerical simulation result, and the evaluation model is proved reasonable and practicable.%针对盐岩储气库运营期稳定性影响因素的复杂性,利用层次分析法,建立了盐岩储气库运营期稳定性评价指标体系.在结合判断矩阵对各指标进行权值分配的基础上,运用灰色关联分析理论,提出了储气库运营期稳定性灰色关联评价模型.将指标的关联系数与其权值相结合,最终以关联度为定量指标,对储气库运营期稳定性进行比较分析,并结合工程实例,将评价模型应用到3个处于运营期的储气库中.评价结果与数值模拟结果相一致,说明了该评价模型具有较强的合理性和可行性.
