摘　　要：通过对大庆油田近5 a潜油电泵失效泵轴的数据统计,应用可靠性分析理论和方法,从无参数统计分析、有参数分布类型统计分析和失效件形貌分析3个方面进行了泵轴失效规律研究,得出泵轴的主要失效模式是磨损;统计样本在1 a保修期的故障率为39.5%,可靠度为0.986。并对泵轴失效因素和控制措施进行了探讨。Based on the data statistics of the failure shaft of electrical submersible pump in Daqing Oilfield in the recent five years, study on the regularity of shaft failure is carried on by using reliability analysis theory and method in three respects： non-parameter statistic analysis, parameter distribution pattern statistic analysis, and failure shaft appearance analysis. It＇s concluded that the main cause of the shaft failure is wearing. The failure rate of the samples within the guarantee period of one year is 39.5%, and the fiduciary level is 0. 986. The shaft failure factors and control measures are also discussed.
