扶正器钻具组合在定向井施工中的应用

本文介绍了单扶钻具组合、双扶钻具组合的特点及用途,分析了影响井眼轨迹控制的因素,并结合现场应用,分析了扶正器钻具组合对定向井施工的影响。实钻结果表明调整单扶正器组合中扶正器的安放位置,可以获得理想的稳斜效果,既能保证井下安全,又能实现定向钻井的目的,是理想的钻具选择。

The feature and the functions of single drilling centralizer assembly and double drilling centralizers assembly,inthis paper are introduced analyzing the influential factors of the wellbore trajectory,and related the application,analyzing the affections of the drilling centralizer assembly to the directional wells.The result prove that regulating the place of the drilling centralizers in the drill assembly may arise from a good hold angle.It can insure the safe of the well and achieve the aim to the directional drilling.So the drilling centralizer is a good drilling tool chose.
