摘　　要：地下储气库研究中,断层封闭性强弱是影响断块建库成败的关键。采用断层走向与应力方向关系、断层的活动时期、断层两盘的岩性配置关系、断层两盘的油水关系、断块生产动态5种影响因素对板南地下储气库的断层封闭性进行定性判别,采用断层泥分布率、泥岩涂抹系数法对断层封闭性进行定量判别,确定了板南地区BG1断块断层具有良好的封闭性,并在开发应用中得到证实,为断块型地下储气库的封闭性评价提供了借鉴。During the underground gas storage study, the strength and the weakness of the fault sealing is the key. The five influencing factors were used to qualitatively distinguish the fault sealing in Bannan underground gas storage, which are the relationship between the fault trend and stress direction, the fault active period, the lithology matching relationship between two sides of the fault, oil and water relationship between two sides of the fault and production state of the fault block, while the distribution rate of fault gouge and the method of shale smearing coefficient were used to quantitatively identify the fault sealing. Therefore, it was determined that the fault of Bannan BG 1 fault block has good sealing property, which has been confirmed in the practical applications. It provides a reference for the evaluation of the fault type of the underground gas storage sealing.
