摘要
抽油杆作为抽油系统的重要部件之一,其疲劳寿命的可靠度严重影响整个抽油环节。由于抽油杆个体差异和各种随机因素的影响,其疲劳寿命具有分散性,需要通过统计推断对其进行分析。通过正态分布的统计方法对抽油杆疲劳寿命可靠度进行研究,从而为油田在选择抽油杆方面提供依据。
Fatigue life reliability of sucker rod seriously is influenced the whole process of pumping as one of the important components of pumping system.The individual difference of sucker rod and kinds of elements resulted in the diversivity of fatigue life reliability of sucker rod,so need analyze it through the statistical methods.The reliability of fatigue life of sucker rod is researched through the statistical methods of the normal distribution,in order to provide basis for oilfield in choosing sucker rod.
