针对地下储气库设计方案优选涉及因素较多的问题,提出基于层次分析法(AHP)和熵权法确定最佳设计方案。采用层次分析法和信息熵方法相结合的组合赋权法确定垫层气量、注气结束时的最大地层压力、注采井数、压气站功率、工程投资和使用寿命等6个评价指标的综合权重,结合层次分析法对各个设计方案与理想解逼近程度的计算,实现方案优劣排序。实例计算结果表明:两种方法结合使用能够同时兼顾主观因素和客观因素的影响,为设计者选择技术上可行、经济上合理的设计方案提供了有效方法,并为优化地下储气库生产运行参数提供辅助决策。
Aiming at the problems that there are many factors involved in the design optimization of underground gas storage, the optimal design scheme based on Analytic Hierarchy Process (AHP) and entropy weight method is proposed. A combination of analytic hierarchy process and information entropy method is used to determine the combination of 6 evaluation indexes such as cushion gas volume, maximum formation pressure at the end of gas injection, well number of injection and production, power of compressor station, project investment and service life Weight, combined with analytic hierarchy process for each design and the ideal solution to approximate the degree of calculation, to achieve program ranking. The calculation results of the examples show that the combination of the two methods can take both subjective and objective factors into consideration, and provide an effective method for designers to choose technically feasible and economically reasonable design schemes. In order to optimize the operation parameters of underground gas storage production Provide decision support.
