为满足我国东部地区经济发展对天然气的需求，落实中石化股份公司天 然气发展战略，对胜利地区油气藏建设天然气地下储气库开展可行性研究。 由于地下储气库的世界方案涉及因素多，须从整体上进行综合评价，客 观合理的确定优选方案。本次研究通过对胜利油气区胜坨、玉皇庙和永安油 气田进行全面对比分析，并考虑到气藏改建为地下天然气储气库的可行性， 最终确定了条件成熟、适合改建为储气库的首选目标区是胜坨一区Es 1 气藏 和永 21 块Es 3 气藏。 全面规划了胜利油气区地下储气库的运行周期、运行方式、运行压力、 运行库容、运行方案，对钻采工艺和地面工程也进行了初步的探讨，并对相 关方案进行了经济评价，结合该地下储气库项目的财务评价分析认为：项目 在经济上总体可行，具备一定的抗风险能力。 关键词：天然气，地下，储气库，可行性 iiFEASIBILITY RESEARCH ON UNDERGROUND NATURAL GAS STORAGE IN SHENGLI AREA (Oil and Natural Gas Engineering) Directed by Li lei Abstract The feasibility of natural gas storage in underground reservoirs in Shengli Area is studied for these purposes of satisfying the demand of economy development in China eastern regions to natural gas, implementing the natural gas development strategy of SINOPEC,and expanding natural gas market of Shandong Province. There are many factors involved inshte design projects of underground natural gas storages.Therefore ,it is necessary to comprehensively evaluate the design projects. To contrast with Shengtuo natural gas reservoir.Yuhuangmiao natural gas reservoir in Shengli area, and estimate the fasibility of make the natural gas reservoir into underground natural gas storage, we made a conclusion that Shengtuo first zone E reservoir and Yong twenty-first zone E reservoir is the beast place to do the work. s1 s3 The essay gives an overall layout of the underground natural gas storage in Shengli oil/gas fieldincluding operation cycle, operation mode, operation storage capacity and operation scheme. The essay also makes a preliminary discussion of the drilling technique and surface engineering, makes the economic assessment of the relative schemes. With the help of the financial assessment of the underground natural gas storage project, we get a conclusion: the project is feasible financially and has anti-risk capability.
