盐穴地下储气库设计方案优选研究

Study on Optimization of Design Scheme of Underground Gas Storage in Salt Cavern

盐穴地下储气库的建设是一项大型、复杂的工程,选择最优的盐穴地下储气库设计方案具有至关重要的作用。针对盐穴地下储气库设计方案优选问题,建立了基于改进熵值法和模糊综合评价的数学模型,考虑了9项评价指标因素,以金坛盐穴储气库为例进行研究。结果表明:方案2是最优方案,与实际相符合,同时,所建立的盐穴储气库设计方案优选模型具有运算时间短,精确度高的特点,为科学地确定储气库设计方案提供了理论参考。

The construction of underground gas storage in salt cavern is a large and complex project, it is very important to choose optimal designing scheme for underground gas storage in salt cavern. Aiming to the problem of choosing optimal designing scheme for underground gas storage in salt cavern, the mathematic model based on improved entropy method and fuzzy integrated judging method was established. Taking into account nine judging factors and taking Jintan salt cavern underground gas storage as an example, the research work was carried out. The results indicate that the scheme two is the optimal scheme, it is correspond with the fact; the mathematic model based on improved entropy method and fuzzy integrated judging method has short computation time and high precision.
