HeBei Solidkey Petroleum Machinery Co., Ltd.

Matrix body PDC bits have better wear resistance than steel body PDC bits, they are  suitable for very deep well drilling, especially for the horizontal directional drilling section that depth exceeds 2500 meters.

As the development of hard-facing technology, steel body PDC bits become to be higher wear resistance, steel body PDC bits are used more and more by its higher ROP, safer drilling and lower cost. But in very deep horizontal directional drilling section, matrix body PDC bits still have advantage of longer working life to avoid bit replacement.

14 3/4" (374.7mm) IADC537 API TCI Tricone Rock Roller Bits For Well Drilling

1. Cutting Structure

The teeth or inserts, mill tooth tricone bits must be hard-faced by tungsten carbide coating, the inserts must be high grade tungsten carbide.

The life of rock roller bits mainly depends on both teeth/inserts life and bearing life.

2. Gauge Structure

Optimized gauge protection design could keep the diameter fixed from top to bottom of hole to avoid shrinkage.

3. Bearing Structure

IADC537, the 3rd number 7 means journal sealed bearing with gauge protection on heel of cones.

4.Seal and Lubrication

Sealed bearing and lubrication of bearing is very important for life of rock roller bits, grease compensation system inside arms and cones lubricate bearing by a steady flow of high grade specific grease for rock roller bit only.

Reverse circulation is a type of drilling technology, the mud fluid inside drill pipe goes from bottom to ground, big size rock chips could be sucked away from hole bottom to avoid breaking repeatly, so the drilling speed is much faster and high efficiency.

Polycrystalline Diamond Compact Bit is always named PDC bit, it is a type of diamond bits widely used in oil/gas well drilling, it has much longer working life than tricone bit, and the steerable feature is very good in horizontal directional drilling .

Polycrystalline Diamond Compact Bit has amazing performance in drilling steady rocks, one PDC bit could even drill a hole from ground to 2000 meters bottom directly without changing new bit.

Advantage of Steel Body Polycrystalline Diamond Compact Bit:

1> As the developing of hard-facing technology, steel body PDC bit has same wear resistance with matrix body.

2> The steel body is produced from one forging steel, the drilling risk is much lower than matrix body.

3> Steel body could be designed and produced in very sharp style, the ROP(Rate of Penetration) is much higher than matrix body PDC bit.

4> Steel body is much cheaper than matrix body.
