full matrix PDC bit drilling
FM series features
FM series PDC drill bit size range 4 1/2 5/8--17 inch, IADC: from M123 to M433.
According to different formation rock characteristics, optimize the crown profile, optimize the different functions of the composite sheet, to meet the needs of soft to medium hard formation of different drilling.
The cutting structure uses the force balance design, the asymmetrical knife wing, causes the drill bit to work smoothly, has the longer service life.
With independent intellectual property rights of the matrix material, supplemented by by finite element analysis and optimization analysis, from two aspects of material and structure to ensure that bit with better wear resistance and higher strength.
Dynamic flow field simulation technology is used to optimize the hydraulic design of drill bit, and to enhance the cleaning of drill bit, and the cooling effect is to prevent the drilling bit.
The numerical control sintering process adopts automatic control, the whole process monitors the internal and external temperature of the drill bit, give full play to the material properties, and ensure the quality of the product is uniform and stable.

Bit feature |
Arc type double seven toothed blade design, rational allocation of different positions of high quality medium size PDC composite sheet, to maximize the local cutting tooth equivalent density, effectively improve the drill attack and abrasion resistance. The high wear resistance of polycrystalline diamond gage, reduce the rock of the bit wear, greatly increased the gage wear resistance and stability. Brazing specific angle of high wear-resisting PDC, drilling blocked, and in reducing diameter wells pour delimit eye, effectively remove obstacles, and to protect the bit body。 |
