Stabilizer Blade Taper Angle

The gauge diameter of a stabilizer blade is more than the mandrel or the main body of the stabilizer. A taper is provided from the main stabilizer body to the blade pad. The taper angle is defined as the angle of the taper to the main body of the stabilizer. Having a taper provides a smooth transition from the body of a stabilizer to the blade of the stabilizer. Having a smooth transition is an important design consideration of a drilling stabilizer. An abrupt transition would result in a shoulder that will make the stabilizer hang up while tripping or drilling.
