【摘要】：地下储气库的建设属于高风险、高投入项目,地下储气库设计方案的优选直接关系到其整体经济效益。为此,综合考虑地下储气库综合费用、垫底气量、最大地层压力、工作井数、压缩机功率及地下储气库的使用寿命等影响因素,将多目标决策密切值法与熵权法相结合,建立了地下储气库方案设计优选模型。以中国某地下储气库为例,对6种设计方案进行优选分析。结果表明:设计方案4为该地下储气库设计的最优方案,与相关文献的优选结果存在一定的微小偏差,是由于增大了地下储气库建设综合费用的权重,这也正符合地下储气库这种大型地下工程偏重技术经济的要求。验证结果表明:所建熵权-密切值法地下储气库设计方案优选模型具有较高的推广应用价值,能够为地下储气库设计方案的优选提供有益的指导。
[Abstract]:The construction of underground gas storage is of high risk and high investment. The optimal selection of the design scheme of underground gas storage is directly related to its overall economic benefits. Therefore, considering the comprehensive cost of underground gas storage, gasket gas volume, maximum formation pressure, number of working wells, compressor power and service life of underground gas storage, the multi-objective decision making method is combined with entropy weight method. The optimal selection model of underground gas storage scheme is established. Taking an underground gas storage reservoir in China as an example, 6 kinds of design schemes are selected and analyzed. The results show that the design scheme 4 is the optimal scheme for the underground gas storage, and there is a slight deviation from the optimal selection result of the related literature, which is due to the increase of the weight of the comprehensive cost of the underground gas storage construction. This is also in line with underground gas storage such as large underground engineering emphasis on technical and economic requirements. The results show that the optimal selection model of the entropy weight-close-value method for underground gas storage has a high value of popularization and application, and can provide useful guidance for the optimization of underground gas storage design.
