WLD型稳定器是利用其结构本身偏重原理，在钻具旋转时产生一个朝向重边的离心力。钻具每转一圈就会有一次自然减斜力和偏心力重合。这对井壁产生较大的冲击纠斜力，使井眼逐渐变直。因此，偏重单螺旋及多头螺旋稳定器是钻定向井较理想的防斜工具。
The unbalanced spiral blade stabilizer, relying on its structural unbalanced principle, during rotating of drill string, produces a centrifugal force toward weighted side. One time natural coincidence for restoring force with eccentric force whener drill tool turns a round. This would produce a large impact restoring force to straighten well-bore gradually. Therefore, both single-spiral blade stabilizer and multi-spiral blades stabilizer are ideal anti-inclination tool
