【摘要】 随着我国盐岩地下储气库大规模兴建的开始,如何对各目标盐矿区进行储气库库址的评价和优选已成为国内储气库建设面临的首要问题。在对盐穴储气库选址的影响因素进行详细归类和分析的基础上,应用层次分析法建立盐穴储气库选址综合评价体系的目标层次结构模型,并结合专家调查法,确定了该模型中18项基本指标在整个选址评价体系中所占的权重。综合本领域专家的意见和相关的理论研究成果,提出了选址体系中各基本指标的适宜度等级划分标准,以及库址综合适宜度等级评价标准,综合各指标的权重计算结果,建立了目标库址综合建库适宜值P的计算公式,为我国盐穴储气库库址的评价和优选提供了可行方法和理论依据。将该方法应用于湖北云应盐矿的盐穴储气库库址评价中,评价结果与专家论证意见一致,表明了该方法的合理性。更多还原

【Abstract】 The problem of site selection evaluation for salt cavern gas storage arises along with the rapid development of salt cavern gas storages.Based on the classification of the influence factors and the analysis of site selection for salt cavern gas storage,Analytic hierarchy process is used to build a layer structural model.Using expert investigation method,the importance weights of 18 influence factors are obtained.Then taking the advices of the experts on salt cavern gas storage building and the related research results into consideration,index suitability standards and synthetical evaluation standards of site selection evaluation for salt cavern gas storage are put forward.Combined with the importance weights of 18 influence factors,a formula is developed to calculate the synthetical appropriate value P of site selection.The results provide a feasible method and theory for the construction of salt cavern gas storage in China.Finally,this method is used to evaluate the suitability of building salt cavern in Yunying salt mine.The result is consistent with the expert opinions,which shows that this method is reasonable.更多还原
