摘　　要：断层密封完整性动态评价是地下储气库建设、运行管理中的瓶颈技术,断层封闭完整程度直接影响地下储气库运行的可靠性和经济性。以板中北储气库为例,综合定性和定量方法,系统评价了板中北储气库断层封闭完整性,形成自然伽玛多元回归法评价储气库断层封闭完整性的方法。储气库渗透率与泥质含量关系图版和储气库断层封闭完整性评价分级表,可以为其他储气库断层封闭性评价提供评价标准。建议在现有储气库断层外部储层部署适当的监测井,实现在储气库生产过程中,对断层的长期动态监测,以此作为储气库储层完整性管理的重要技术手段。Dynamic evaluation on fault seal integrity is a bottleneck in the underground gas storage construction, operation and management, because fault seal integrity directly affects the reliability and economy of underground gas storage＇s operation. In this paper, taking the Banzhongbei Gas Storage as an example, a systematic fault seal integrity evaluation is given by integrating qualitative and quantitative methods, and the evaluation method based on multiple regression of natural gamma is established as well. Moreover, the permeability and clay content diagram and the fault seal integrity evaluation and ranking table given in this paper provide a reference for the fault seal integrity evaluation of other gas storages. It is recommended to deploy appropriate monitoring wells in the external reservoirs of existing gas storages to achieve long- term dynamic monitoring of faults in the production process, and take this as a major method for the gas storage reservoir integrity management.（4 Tables, 5 Figures, 13 References）
