Integral blade stabilizer is an important tool in the drilling engineering to control the well deviation. It can stabilize the drilling tools in the drilling process of oil, gas and geological exploration. It can increase the bit life, drilling speed and well bore quality. There are two kinds of integral stabilizers: spiral integral blade stabilizer and straight integral blade stabilizer.1. 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.
To meet a variety of the most demanding drilling conditions, we offer hardfacings in five different options for our stabilizer blades. We are constantly working to develop improvements on wear characteristics and matrix hardness. With our unique hardfacing capabilities, this tool can be dressed with five hardfacing materials, including HF1000 for soft formations and HF3000 for nonmagnetic stabilizers. In hard or abrasive formations, HF2000, HF4000 and HF 5000 hardfacing will extend this tool’s lifespan by 3x-5x longer making it a very economical choice.
2. HF2000-Trapezoidal tungsten carbide inserts held in a sintered carbide nickel bronze matrix. This will give a great depth of carbide coverage-ideal for high deviation drilling in abrasive formations.
3. 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.
4. 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.
5. 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.
