天然气能源在地下储气库的存储及利用

地下储气库对调节冬夏季节天然气供需矛盾,保障用户需求、优化集输系统功能有重要作用。在对地下储气库概念及原理进行阐述的基础上,系统地给出了地下储气库的研究设计模式,提出了建立地下储气库应具备的首要条件,同时对地下储气库设计过程中应重点解决的问题及指标设计进行了详细论述。通过大港油区地下储气库地质方案设计的探索实践,证实了所提出的设计及评价方法的可行性。

Underground storage and utilization of natural gas resource

The natural gas storage in underground reservoir is of paramount importance to solving supply-demand contradiction of gas energy in winter and summer seasons, guaranteeing users demand and optimizing transferring system of natural gas. Based on the concept and principle of underground reservoir for natural gas that are expounded in this paper, it proposes the pattern for the study and design of the reservoir, puts forward the condition of first importance to construct the underground reservoir and simultaneously discusses in detail the key problem and the design of index in the stage of designing underground gas reservoir. The feasibility of design and evaluation methods proposed in this paper has been proved by the geological design plan for the underground gas reservoir of Dagang oil field.
