INTEGRAL BLADE STABILIZER: 

Tianhe integral blade stabilizer (IBS) is a one piece rotating stabilizer which can be placed near bit or up on the drill string. It is a one piece construction manufactured from high strength alloy steel (non-magnet steel optional). It prevents differential sticking of the drill string by stabilizing the BHA and keeping drill collars and drill pipes away from the borehole wall. This reduces vibration, drill pipe whirl, and wellbore tortuosity, furthermore, the stabilization maintains drilling trajectory whether drilling straight, horizontal, or directional wells.

Optional stabilizers:

Tianhe offers several options for IBS, in both alloy steel and non-magnet materials;

Spiral integral blade stabilizer;

Straight integral blade stabilizer;

Non-magnet integral blade stabilizer;

When ordering pls specifies:

Special features SRG on connections, bored for float etc.

Spiral integral blade stabilizer 

Straight integral blade stabilizer 

Non-magnet integral blade stabilizer 

Non-rotating stabilizer 

Tianhe non-rotating stabilizer (rubber sleeve stabilizer) is a special tool in drilling to avoid blade wear and wall damage. The non-rotating stabilizer consists of mandrel, copper washer, rubber sleeve, spacer sleeve and self-locking lower sub.

During drilling, the non-rotating stabilizer transfer the torque by means of mandrel, the rubber sleeve is sliding and moving relative to the mandrel, the rubber sleeve thus plays a role in stabilizer of well. A locking clutch (self-locking lower sub) will avoid sleeve rotation during wash over operation.

When ordering pls specify:

Casing size and weight;
Hole size or required blade O.D:      
Top and bottom connections.
Replaceable sleeve stabilizer consists of an integral mandrel and a sleeve. One mandrel series can be equipment with different size of sleeve for several hole sizes. The sleeves are easily changed on the rig floor, either when changing hole size or changing the type of wear surface to match drilling conditions.

When ordering pls specify：

Mandrel series and sleeve O.D
String or near bit application.
Top and bottom connection
Hard facing type
Hard facing types of stabilizer；

We offer a complete range of hard facing to suit all drilling conditions. All tianhe stabilizers can be banded with following hard facing:

HF1000: crushed tungsten carbide held in a nickel bronze matrix. The 3mm grain size ensures greater concentration of carbide which is ideal for soft formation drilling.

HF2000: trapezoidal tungsten carbide inserts held in a sintered carbide nickel bronze matrix. This will give a greater depth of carbide coverage-ideal for high deviation drilling in abrasive formations.

HF3000: tungsten carbide inserts set in a powder spray deposit ideal for abrasive formations. 97% bonding guaranteed, certified by ultrasonic report. Recommended for non-magnetic stabilizers.

HF4000: tungsten carbide inserts (button type). The inserts have been developed to allow cold insertion and maintain close fit. A greater concentration of inserts on the bottom third of the blade and leading edge will increase surface contact to reduce wear in highly abrasive formations.

HF5000: this oxy-acetylene process applies tough molten carbide particles of varying sizes held in a nickel chrome matrix which provides excellent bonding properties and greater surface wear characteristics are achieved. Surface hardness levels over 40HRC. Ideal for GEO-THERMAL application over 350°

HF6000: this process is a highly automated way of applying hard face and utilizers a combined arc/plasma stream on the work piece surface. This results of a low base metal dilution and a dense, uniform coating, the filling medium can be variety of hard facing consumables.
