利用偏心钻具在旋转过程中的离心力和偏心短钻铤的偏重带的支撑作用，减小了钻头轴线倾角，从而减少了井斜。
By taking advantage of rotating centrifugal force and the supporting effect of eccentric short drill collar, we cut off the axis inclination of bit, and avoid well inclination.
弯曲平面倾角和井眼曲率的有机结合可以很好的描述井眼轨迹空间形状对钻头侧向力的影响。
The curvature rate and well curvature plane Angle can be used to make a good description of the influence of the well trajectory parameters on the side fo.
