| 经长输管线输送的天然气注入到地下空间而形成的人工气藏称为地下储气库。国内外现有储气库大多数是枯竭气藏型地下储气库。中国石化储气库建设起步较晚，基础较为薄弱，同时与国内外已建成储气库相比，中石化储气库建设面临的地质条件和注采工况也较为复杂。以中国在建最大储气库项目中原文23储气库为例，其复杂地质条件以及面临的“快瞬变非稳态增压”注采难题需要进行专门研究。分析了目前中石化枯竭型气藏储气库建库现状，提出了建库技术挑战，总结了现阶段取得的注采关键技术研究成果，通过分析中国石化枯竭气藏型储气库注采技术研究现状和最新进展，提出了国产化技术完善、智能化注采营运、一体化模拟实验室的建设等方面的发展建议和要求，为持续加强规模化储气库群建设的支持提供参考。 |
| 英文摘要: |
| The underground gas storage is artificial gas field or gas reservoir formed by re-injecting commercial natural gas by a long-distance pipeline into the underground space. Most of the existing gas storages at home and abroad are of the depleted gas reservoir type. The construction of Sinopec gas storage started relatively late, with a relatively weak foundation. At the same time, compared with the established gas storage at home and abroad, the geological conditions and injection and production conditions faced by Sinopec are more complicated. Taken the Wen 23 gas storage of the China's largest gas storage project as an example, its complex geological conditions and the “quick transient unsteady boost” injection and production problems need special research. This paper analyzes the current status of gas storage in Sinopec's depleted gas reservoirs, proposes the technical challenges of database construction, summarizes the research results of key technologies for injection and production obtained at this stage, and analyzes the injection and production technology of Sinopec's depleted gas reservoirs and the latest development. Finally, this paper presents development proposals and requirements for the improvement of localized technology, intelligent injection and production operations, and the construction of integrated simulation laboratories, which provide references for the support of sustained strengthening construction of large-scale gas storage groups. |
