摘　　要：在带压作业中,起下油管在受到轴向力或偏心载荷的情况下往往会偏离井口中心位置,为此设计了一个新型油管扶正装置。首先对其进行结构设计,然后计算选取了对扶正效果起主要作用的扶正弹簧,最后对油管与扶正滚轮进行接触应力仿真分析,得出油管接触应力的分布情况。所设计的油管扶正装置,解决了带压作业中接箍报警装置的误报情况,增加了带压作业自动化控制的可靠性与准确性。In the operation with pressure,lifting and releasing the oil tube will make it deviate from the central position of oil well when it tolerate force or eccentric loads,this paper designs a new type of tubing centralizer,mainly concentrates on the structure design,the selection of the righting spring which plays an important role in stabilizing effect,finally carries out the simulation analysis of the contact stress on righting roller and tube,and gets the contact stress distribution of tube.The centralizer designed in this paper solves the problem of the false alarm of collar alarm device,increases the accuracy and reliability of the automatic control in the operation with pressure.
