摘要
论述了使用一种带有"哑铃型"接箍的油管进行单吊卡起下油管的作业工艺。使用这种油管可以避免原来使用动力卡盘进行单吊卡起下作业存在的问题,且配套相应的卡盘和吊卡,可实现起下油管作业的机械化或半机械化。
This article presents an operating process of running and pulling oil tube with dumbbell coupling by single elevator. The application of this kind of tubing can avoid previous problems caused by using power chuck to pull oil tube by single elevator. Besides, matching relative chucks and elevators can achieve mechanization or half- mechanization.
