摘　　要：接箍是石油套管和油管的重要部件,石油套管和油管通过接箍以螺纹拧接的方式连接成油井管柱。为了更好地提高接箍的螺纹抗粘扣性能,通常对接箍采用高温锰系磷化处理,可以起到防腐以及减少摩擦、提高润滑性能的作用。文章通过试验研究游离酸度、总酸度、酸比对磷化膜质量及磷化反应时间的影响,进一步优化磷化工艺参数,将磷化膜的膜重控制在一定范围内,获得更致密、更均匀的磷化膜。The coupling is an important part of oil casing and oil tube as well as they are connected into tubing string by coupling with the mode of screw joint.In order to improve the anti-galling property of thread of coupling,the high temperature manganese phosphating is usually adopted for coupling so that it is corrosion resistant,the friction is reduced and lubrication performance is improved.In this paper,the effects of free acidity,total acidity and acid ratio on the quality of phosphating film and phosphating reaction time are studied by experiments.The phosphating process parameters are further optimized to control the phosphating film weight to be within certain range so that more compact and homogeneous phosphating film is obtained.
