Unbalanced Single-spiral Blade Stabilizer / Multi
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
