摘　　要：目前国内外尚没有氮气备用系统现场可靠性应用的相关数据及说明,为了评估氮气备用系统现场实际应用的可靠性,计算了有效关井容量并进行了现场联机试验。试验结果表明:在紧急情况下使用氮气备用系统不仅可以成功关井,而且确认使用氮气备用系统不会对其他关联系统造成损坏,为氮气备用系统的现场使用提供了可靠性依据。So far till now, there is no data and description about the reliability of the nitrogen back-up system＇s application in the domestic and overseas. In order to evaluate the safety and reliability of the nitrogen backup system, the effective shut-in capacity of the BOP was calculated and an on-line experiment with the BOP was carried out. The result of the experiment shows that in case of the emergency,just using the nitrogen backup system can shut in the BOP stacks and make no damage to the related systems. The experiment provides a basis for the reliability of the applica-tion of the nitrogen backup system.
