硬岩地区压缩空气储能工程地下储气洞室选址方法研究

Underground Gas Storage Cavern Location Method for Compressed Air Energy Storage Engineering in Hard Rock Area

通过对国内外类似工程案例的分析,总结了在硬岩地区修建压缩空气储能工程地下储气洞室的关键技术点,提出了硬岩地区地下储气洞室的场址选址、围岩识别、洞室范围确定等原则,并引入了层次分析法,建立了硬岩储气洞室选址综合评价体系。该体系中包括5个准则层因素和19个评价层因素,建立了利用两两比较判断矩阵得到各个指标的权重值的方法,为评价候选场址的适用性提供依据。

Through the analysis of the similar engineering cases at home and abroad,this paper sums up the key techniques in constructing the underground gas storage cavern in compressed air energy storage engineering in hard rock area,and puts forward the principles for cavern site location,surrounding rock identification and cavern scope.Then the analytic hierarchy process（AHP）is introduced to set up the comprehensive evaluation system for gas storage cavern site selection,which includes 5 criterion factors and 19 evaluation factors.The pairwise comparison judgment matrix is applied to achieve the weight value of each index,providing the basis for evaluating the applicability of the suitable candidate site location.
