摘　　要：储气库能否储存天然气并在气库运行过程中不发生泄漏,主要取决于盐穴腔体及井筒的密封性能,而盐穴腔体密封性能的影响因素很多,影响机理复杂,故深入研究盐穴腔体密封性能影响因素具有重要意义。从地质、工程和工艺3方面详细分析了影响盐穴储气库密封性能的各项因素,根据现场施工经验及国外储气库泄漏事故产生的原因统计,确定出储气库密封性能的主要影响因素,给出主要因素导致气库产生泄漏或破坏的条件,提出了相应的预防措施,现场应用效果良好。Whether the gas storage can store natural gas and can avoid gas leakage during the operation mainly depends on the sealing property of the salt cavern and well bore.There are numbers of influence factors for the sealing property of the salt cavern and the influence mechanism is complicated.The deep researches on the factors which influence its sealing property are of great significance.Accordingly,the paper studied these factors in terms of geology,engineering and process.These factors were confirmed in accordance with the on-site construction experience and the statistics on the gas leakage accident and gas storage destruction in some other countries.The paper figured out the condition under which gas leakage and gas storage destruction might occur and brought forward the preventive measures which have been proved to have favorable on-site application effect.The research results will provide guidance to the sealing theory of salt cavern gas storage and gas storage security.
