Integral spiral blade string drilling stabilizer on oilfield for drilling down hole tools

Short Description:

Integral Blade Stabilizers are manufactured from 4145H alloy steel bar or forgings, quenched and tempered to 285-341 Brinell hardness;
Stabilizers are fairly short subs which have blades attached to their external surface. By providing support for the BHA (Bottom Hole Assembly) at certain points they can be used to control the trajectory of the well. The blades can be either straight or spiral in shape. Spiral blades can give 360° contact with the borehole.
