The new PDC bit can play an important role in use and value in use can fully demonstrate the advantages and the role of good performance. Even in the development of low levels of wear, PDC will be significantly reduced efficiency of drill bits, it is recognized. Maintain the efficiency and the penetration rate, the key is to ensure the drill bit cutting structure is still acute. Application of a new multi-PDC cutter technology to add more predictable ROP. Tungsten carbide is not formed by the interface to reduce the production of residual stress, the multi-layered diamond technology and proprietary matching technology provides significant anti-wear ability and tremendous impact toughness. Two lessons under the bit of experience, PDC drill bit in the Berkine third area "B" oil drill. This is a development well, there can be used as the baseline (existing) object. In the upper well section, Aptian strata of the lower part, based on the requirements of the operator control parameters. 
 New design is a result of the cutting teeth with a 16mm 6 blade bit, but also with a 13mm back-cutting teeth to protect vulnerable gage section and shoulder area. Reduce the number of blades to make room for a wider flow profile to accommodate the expected volume of cuttings. PDC bit dynamic simulation program with special blades arranged symmetrically designed so that a drill at a new level of stability, significantly reduced the frequency and the bit when drilling dysfunction damage. Reduction of the main cutting teeth, the natural increase of the workload of each cutting tooth, spare arrangement reduces the cutting teeth cut teeth most vulnerable effective work, but also reduces the exposure to each cutting tooth maximum dynamic load. Bit more aggressive drilling parameters to 40.3m / h to complete the drill. Can be proved by the drill bit has a good stability, there is very good and stable torque value, the adoption of MaIm, DoggerAn-hvdrite and LiasAnhydrite hard formation was observed only when the medium sticking or sliding. This proves that anti-vibration measures are effective to prevent premature damage to the drill bit. 
 This time in the "B" field completed the longest drill hole section (2118m), while in the field created ROP records, and reduce operating costs. In the field, so that the work of the feature is considered to be the best, because in comparison to other drilling, the drill bit and an additional 40m of hard strata. From the drilling, the drill bit has a good condition, once again applied the higher pressure drilling drilling still room for improvement. 
 The new PDC bit unique process and methods of processing and production, to ensure good performance in the use of the advantages and role in ensuring that in use to improve the efficiency and value to bring respect for different users.
