摘　　要：针对油田开发后期井况日益恶化 ,油管偏磨腐蚀加剧等问题 ,研制了一种新型转动井口 ,该新型转动井口可改变油管的偏磨位置 ,延长油管的使用寿命。与常规的转动井口相比具有结构简单、转动灵活、使用寿命长、成本低等特点。现场应用情况表明 ,该工具的应用可有效地减缓油管的偏磨 ,延长检泵周期。As the deterioration of hole condition and off center wear of tubing become more and more serious in later field life, the advanced rotary christmas tree was developed. This christmas tree can change the off center wear position and elongate the life time for tubing. Compared with the common one, it has features as simpler structure, more flexible rotation, longer service life and lower cost and so on. The application indicated that this tool can retard the off center wear of tubing and extends the pump maintenance cycle.
