斜井钻机技术在 90年代初期得到发展 ,当时Precision钻井股份有限公司与PanCanadian石油股份有限公司合作共同设计并制造了一种新型斜井钻机。其钻杆长 4 5ft (13m ) ,被称作“超长单根” ,比标准钻杆 30ft (9m)长 ,因此钻机灵活性大、作业能力强。新型斜井钻机还具有远程控制能力强、安全性好、钻井效率高等一系列优点 ,并在现场应用中得到了好评。这一新型设计是稠油钻井中的一个重要里程碑。新型斜井钻机在钻井时间和作业成本上都节省很多 Inclinometer technology was developed in the early 1990s when Precision Drilling Co. Ltd., in collaboration with PanCanadian Petroleum Co., Ltd., co-designed and built a new incline rig. The drill pipe is 45 ft (13 m) long and is called “extra long, single” and is 30 ft (9 m) longer than a standard drill pipe, making the drill flexible and workable. The new inclined drilling rig also has a series of advantages of remote control, good safety, high drilling efficiency, and has been well received in the field applications. This new design is an important milestone in heavy oil drilling. The new inclined drilling rig saves a lot of time and effort on drilling
