Product Description
Product Description
Overview: drilling tool stabilizers are important tools used to prevent vertical well from tilting or directional well, cluster well and horizontal well from maintaining the same angle. It is able to prolong the servicing life of the bit, increase its drilling speed and improve the wellbore quality. Drilling tool stabilizer, integral straight-edge stabilizer and three-wheel stabilizer. Structural features: there are two types of drilling tool stabilizers: the drill-stem type and the well-bottom type, which are all manufactured of superior alloy steel forgings with advanced technologies. The operating surface of the stabilizer is inlaid with carbide column and its hardness is no less than HRA85. So it boats advantages of its simple structure, superior bending resistance, pressure resistance and small rotational resistance. This product is designed and manufactured in accordance with the petroleum and natural gas industry standard of People's Republic of China Drilling Tool Stabilizers (SY/T 5051-2009) and API7-1 standard.

STABILIZER
Four designs are available as below:
1) Integral spiral type
The Integral spiral stabilizers are made from AISI 4145 H Modified alloy steel or Non-magnetic alloy steel, the pressed button type or applied tungsten carbide hard faced on the blade.
2) Intgral straight rib stabilizer
3) Interchangeable sleeve stabilizer
Interchangeable sleeve stabilizers are made of 4145 H Alloy steel, heat-treated to 285-341 Brinell Hardness and 54 Joules minimum impact value. All physical properties would be guaranteed 1" under the surface. The stabilizer is constructed of two pieces, which are jointed, by the center mandrel and one sleeve.
