摘　　要：为实现修井作业机械化,油管由井口至管排的拉斜及扶正均需机械化实现。为此设计的油管扶正装置由井口支架、扶正液压缸、导向锥桶、辅助扶正臂、主扶正臂以及机械扶手组成。为使主扶正臂及辅助扶正臂更好的实现六杆联动空间夹持技术,利用MATLAB软件对辅助扶正臂的运动轨迹进行优化设计。通过对计算结果进行模拟分析,计算结果满足设计要求。同时现场应用结果表明,该辅助扶正臂能够很好实现让位及较快的辅助主扶正臂实现油管的扶正,满足现场应用的要求。In order to achieve the mechanization of well overhaul operations,the pulling and centralizing of tubing from the well head to the pipe rack is required to be mechanically performed. For this purpose,the device of the tubing centralizer was designed,composed of a wellhead bracket,a hydraulic cylinder for centralizing,a cone-guide bucket,an auxiliary arm,the main supporting arm and a mechanical arm. In order to make the main supporting arm and the auxiliary stabilizer realize sixrod linkage spatial clamping,MATLAB software was used to optimize the movement track of the auxiliary arm. Through simulation analysis on the calculation results,the calculation results were proven to have met the design requirements. And the field application showed the device could assist the main arm to centralize the tubing quickly without manual operation.
