The invention provides an oil pipe traction system for hoisting an oil pipe under pressure and a hoisting method. The oil pipe traction system comprises a guide rope, a traction rope, a sliding deviceand a hoisting device, wherein one end of the guide rope is connected with an operation table, and the other end of the guide rope is fixed to the ground; the sliding device is arranged on the guiderope and can slide on the guide rope; one end of the traction rope is connected with the sliding device, and the other end of the traction rope is connected with the lower end of an oil pipe; and thehoisting device lifts the oil pipe so that the oil pipe can ascend along the guide rope through the traction rope, and the hoisting device lowers the oil pipe so that the oil pipe can descend along the guide rope through the traction rope. The hoisting method comprises the step of hoisting the oil pipe through the oil pipe traction system. The oil pipe traction system has the beneficial effect ofbeing applicable to automatic traction and guide of the oil pipe in the process of lifting and lowering the oil pipe under pressure.

    本发明提供了一种带压作业起吊油管的油管牵引系统和起吊方法。所述油管牵引系统包括导向绳、牵引绳、滑动装置和起吊装置,其中,导向绳一端与操作台连接,导向绳的另一端固定于地面;滑动装置设置于导向绳上,并能够在导向绳上滑动;牵引绳一端与滑动装置连接,牵引绳的另一端与油管下端连接;起吊装置通过吊起油管,使得油管能够通过牵引绳沿导向绳上行,所述起吊装置通过下放油管,使得油管能够通过牵引绳沿导向绳下行。所述起吊方法包括通过上述油管牵引系统起吊油管。本发明的有益效果可包括:可应用于在带压作业起下油管作业过程中以进行油管自动牵引导向。
