通过优化双稳定器滑动导向钻具组合的结构参数，可以获得较单稳定器滑动导向钻具组合更高的导向能力。
Comparing with single stabilizer slide - and -guide BHA, a better steering ability can be achieved through optimizing the structure parameters of double stabilizer slide - and - guide BHA.
同时以一组双稳定器钻具组合为例，分析钻具节点的位移变化图、弯矩图和应力分布图可得出钻具上的受力变形情况。
Moreover, taking the BHA with two stabilizers for example, based on analyzing the displacement, bending moment and stress on the nodes of BHA, the force and deformation of BHA are obtained.
为保证井下安全，气体钻井常常不使用或少使用稳定器，此时钻具组合更易发生弯曲而引起井斜。
Stabilizer is not used or used seldom in gas drilling to ensure the downhole safety. At this time, bottom-hole assembly bends easily resulted in well deviation.
常规的、不可变径的钻柱稳定器现在依然是井斜控制井底钻具组合中不可缺少的组件。
The ordinary non-adjustable stabilizer is still now an indispensable element of DHA(Down-Hole Assembly) for controlling well inclination.
