摘　　要：采用正交试验法揭示了影响水驱抽油机井管杆偏磨的人为控制因素对检泵周期影响的规律性,从中找出各因素对检泵周期影响的主次关系,并确定出最优的工艺条件组合;运用方差分析理论处理试验结果,得出各因素对管杆偏磨井检泵周期影响的显著程度,从而发现最薄弱环节,为控制管杆偏磨失效,降低水驱抽油机井检泵率提供依据.This paper presents the rule of the main controlling influencing factors of water drive off-center wearing and parting of sucker rod and tubing in pumping well to check period with the orthogonal test method,then finds which is the most important,establishes the best process condition unit.We handle the test result with the variance analysis method,study the degree that every factor affects on the check period for off-center wearing and parting of sucker rod and tubing,then find the most vulnerable spots.It offers sufficient evidence for dealing scientifically and controlling efficiently off-center wearing and parting of sucker rod and tubing failure,reducing the check rate of water drive pumping well.
