摘　　要：抽油井杆断脱是影响油田正常生产的主要因素之一,根据新疆油田抽油井现状,对引发杆柱断脱的影响因素进行了研究分析,认为采出液性质、井身结构、举升参数以及遇卡受阻是导致抽油杆断脱的主要因素。通过工艺改进和技术创新形成了一套相适应的防断脱工艺,进行了现场试验,平均检泵周期延长157d,取得了较好的应用效果。Sucker-rod-break-off is one of the main factors that affect the normal production of oilfields.According to the current situation of Xinjiang oilfield,through the research and analysis on influencing factors,the produced fluid properties,well structure,lifting parameters as well as stuck pump are considered to be the main factors.Through process improvement and technology innovation,a set of suitable prevention process of sucker rod breaking has been formed.Through the field tests,the average pump detection period extended by 175 days and achieved good results.
