摘要
天然气地下储气库的建造 ,是从根本上解决城市季节性调峰 ,平抑供气峰值波动的最合理、有效途径之一。但由于实际储库地质构造的非均质性以及储层存储和传输流体能力的不同 ,在调峰时必须对库内各注采井进行合理的配产。文章通过分析水驱气藏型地下储气库的注采动态特征 ,建立了库内注采井夏注冬采的数学模型 ,采用全隐式牛顿迭代法 ,以储库地层压力和含水饱和度为约束条件 ,数值模拟出各注采井的注采运行动态 ,并对其主要影响因素进行了分析 。
The construction of underground natural gas storge is one of the most reasonable and effective ways for basically surmounting city seasonal peak shaving and stabilizing peak waving. Owing to the heterogeneity of geological structure used as underground natural gas storage and different capacities of storing and transmitting fluid in reservoir, it is necessary make a reasonable proration for each member of the injection and production wells within the storage during peak shaving. In this paper, through analyzing the injection-production performance characteristics of the underground natural gas storage of water-drive gas reservoir type,a summer-injteting and winter-producing mathematic model for the injection and production wells within the storage is set up; by taking the underground storage pressure and water saturation as the restrictive conditions, the performance of each member of the injection and production wells is numerically simulated by use of full implicit Newton iteration; and its major influence factors are analyzed, thus providing a theoretical foundation for the optimization running of a practical underground natural gas storage.
