摘要
为提高D级抽油杆接箍的疲劳强度,以适应和满足国内油田及国际市场的需要,从φ24.37、φ27.43、φ30.47、φ35.30、φ40.26mm系列D级抽油杆接箍内螺纹挤压丝锥的设计、挤压工艺的优化和延长挤压丝锥寿命三个方面进行了研究。研究结果使挤压丝锥的寿命成倍提高,接箍内螺纹质量达到API标准,取得了明显的技术经济效益。
In order to improve the fatigue strength of couplings for API Class D sucker rods, the authors make a study of the squeezing taps for rod coupling threads in three aspects——tap design, optimum squeezing technique and measures for increasing tap life. The study results in doubled tap life and optimum quality of coupling threads.
