8 1/2" Cone Hole Opener,
36 Inch 915mm Hole Opener,
915mm HDD Hole Opener
Horizontal Steel Tooth Roller Trenchless Cone Hole Opener
Cone Hole Opener Optimized Structure Ingenious Design
The conical reamer is a commonly used reamer in oil drilling and geological drilling. The roller cone opener has the function of impacting, breaking and shearing the formation rock when rotating. Therefore, the tapered hole opener can adapt to soft, medium and hard formations. Especially after the emergence of jet cone bit and long nozzle cone bit, the drilling speed of cone bit has greatly increased, which is a major change in the history of the development of cone openers.
Optimized structure&ingenious design, fasterdrilling speed.
Premium roller cone cutters. Optional for different crossing.
Enhanced TCI Protection on heel of cones and arm-back.
Bunched Tungsten carbide protection on body.
Heavy duty drill collar from petroleum industry.
In view of the different cutting characteristics of the blades in different parts of the cone, the cone blades are placed in the permanent contact area and the wedge blades are placed in the alternating contact area, which greatly improves the drilling efficiency. A diamond blade is set in the permanent contact area of the cone to improve the wear resistance of the cutting structure, and the blade in this area is severely worn. Place the tungsten carbide insert on the top surface of the cone to protect the cone from wear.
2. Table structure
The cutting body is equipped with active cutting protection blades, so that the drill has good cutting protection and drilling ability.
3. Bearing structure
High-precision journal bearings. The ball locks the cone. Hard surface bearing surface. Tapered bearing with anti-friction alloy. Improve the wear resistance and seizure of the bearing. Compared with tri-cone bits, tri-cone bits have larger outrigger bearings, which can withstand higher drilling weights and are more reliable.
4. Hydraulic design
The small-angle waterway design increases the thickness of the shirt hem, which can effectively prevent waterway erosion. The optimized flow structure is adopted to improve the cleaning capacity and ROP.
