天然气地下储气库最优设计方案的确定

Determination of optimal design scheme for natural gas storage reservoirs

天然气地下储气库的建设是一项大型、复杂、具有多目标性的工程项目 ,必须在建设前期对各种设计方案进行充分的技术和工程论证 ,从中确定出最优设计方案 .将灰色系统理论与物元分析法有机地结合起来 ,将各种方案的评价指标按其属性分为三类 ,对储库各方案特征量所具有的灰数特性和各影响因素间的不相容性加以分析 ,提出基于灰色物元分析方法来研究天然气地下储气库的设计方案 ,进而确定最优方案 .算例计算结果客观 ,符合工程实际 .为科学地确定实际地下储库最优设计方案提供了理论依据 .

Using the grey theory and matter member analysis the schemes are classified into three types according to their evaluation indexes, and the character quantity's grey characteristics of each scheme and the incompatibility between the influence factors are analysed. A design scheme is presented for the natural gas storage reservoirs based on the grey matter member analysis, and an optimal scheme is then established. A typical example of natural gas storage reservoirs is given to check the correction of the method. It is concluded that the evaluation of an integration scheme is more objective and practical than the traditional method.
