| 摘 要： | 水平井钻井的最大难题是如何降低钻井摩阻。目前降低摩阻的工具主要有轴承短节、低扭矩钻杆、DSTR短节、振荡减阻器等，而对非旋转钻杆护箍降低摩阻作用的研究较少。与非旋转钻杆护箍相比，其它各种工具均具有一定局限性，主要表现在接头和短节使用太多会降低钻具安全性，容易形成键槽等。腰青33-2HF井水平段钻进时采用非旋转钻杆护箍，大大降低了钻具与井眼的摩阻，使钻速提高了40.40%，钻井周期缩短57.79%，为水平井钻井提供了很好的借鉴。

| Abstract: | How to reduce drilling friction is the most difficult problem in horizontal drilling. Main tools for friction reducing are bearing sub, low-torque drill pipe, DSTR nipple joint, oscillating drag reduction device, only a few research on non-rotational drill pipe protector for friction reducing has been conducted. Comparing with non-rotational drill pipe protector, the other tools have some limitations, mainly in lower safety for too many subs or joints and key seats creating. Non-rotational drill pipe protector was used in the horizontal section drilling of Yaoqing 33-2HF, the friction between drilling tool and borehole was greatly reduced, so that drilling speed increased by 40.40% and the drilling cycle was shorten 57.79%, which provides reference for long horizontal well operation in the future. |
