摘　　要：上扣控制是保证API螺纹油管、套管使用性能的重要环节，现场调查发现，许多滑脱、泄漏、粘结等失效事故均与上扣控制有关。文中分析了目前各种上扣控制方法的优缺点，并针对我国油田上扣控制中存在的问题，提出了相应的改进措施。Control of making up of tubings or casings are an important factor to guarantee their properties in use. Rig site practices demonstrated that most of the cases of their jump out, leak and thread galling are closely related with thread making up control. The advantages and dlsadvantages of actually applied making up control methods are analyzed in this paper and the improving measures are presented in regard to the problems of making up control existent in our oilfields.
