含水层地下储气库参数优化问题分析

讨论了灰色物元法在含水层储气库参数优化问题中的应用。天然气地下储气库的建造是一项大型、复杂、具有多目标性的工程项目,包括固定资产投资、钻井、修井、注采气工艺完善、地面建设等,需要上亿元的投资,因此其方案的确定,事关重大,必须在建设前期进行充分的技术和工程论证。地下储气库设计方案的优选需要考虑使用功能、技术性、经济性、安全性、环境影响等诸方面的效果进行综合论证,来确定最优方案。由于确定地下储气库优化设计指标类型的多样性,不相容性,且其量纲也不尽相同,甚至有些指标只能是定性描述的非量化灰数,这就导致地下储气库建造设计方案的优选是属灰色系统问题。利用灰色物元分析法优选储气库参数,可以使储气库的参数设计达到最佳。

THE OPTIMIZATION ANALYSES OF GAS STORAGE FIELD PARAMETERS DESIGN IN AQUIFER

To build a gas storage field is a large, complex and multi-objectives project. The project is consisting of fixed assets investment, well drilling, well work over, gas injection/production and surface equipment, etc. The total investment is more than a hundred million Yuan, so it is very important to determine the project. It is necessary to carry out sufficient argumentation about technique and engineering in preliminary phase of the project. To determine the optimal plan of the gas storage field project, the overall argumentation includes functions of use, technique, economic, security, environmental impact, etc. should be thought over. Because of the optimum norms of gas storage field are various, incompatible, and their dimensions are different, some norms even are qualitative gray figure. So to determine the optimal plan of the gas storage field project is a gray system. The parameters design of gas storage field can be optimum by use the gray matter analysis.
