Product Description
which is a matrix body PDC bit four of five curved blades using arc-type ang short parabolic shape design, the rational allocation of different functions small size cutters,so that the PDC bit have a strong impact resistant, hyfrualic balance design, with each balde cuttting the amount of displacement is proportational to the volume of cutttings transports to match the PDC bit cutting transports capacity optimization. while using a dynamic flow simulation technlogy to optimize the hydraulic design of the PDC bit, so bottom hole flow field optimization, enhanced PDC bit cleaning, coolling capacity,more optimum bottom hle flow pattern and anti- balling.soft to medium formation with lower compressive strength and good drillalility,such as marl shale lignite,sandstone, anhydrite tuff.etc
Features
1. Tungsten Carbide Matric PDC Possesse high weqar resistance and impact resisitance.
2.Parabolic Crown profile and maximizes junk slot area can clean bit better, and prolong the bit working life.
3.Applying hydraulics balance design,5 renewal nozzles and reasonable nozzles locking angle can gain ideal fluid field in well bottom, fully clean and cool cutter, and prolong the cutter working life.
4. Non- symmetry blade arragement enhances drilling well balance.
5. Optimizaiton for cutter shape, slant angle, cutter numbers prolong the cutter working lift in combination withe high quality PDC cutter, and improve ROP and drilling efficiency.
6.It can be used on rotary or down hole motor.
7.High HIS is recommended.
Product Advantages:
1. PDC cutters for high speed drilling;
2. All cutters are premium grade for extended bit life and durability;
3. Cutter layout is force balanced to drill a precise round hole and reduce bit whirl;
4. Large junk slots and flushing ports;
5. Advanced geometric design for faster penetration;
6. Gauge pads have tungsten carbide inserts for maximum wear resistance.
PDC Bits' ,Diamond Bits' cutter exposure is optimized to insure the bit can achieve higher ROP is soft to medium formations. 1.Cutting structure is force balanced and bit blade is asymmetrically designed so that the load on bit is balanced that resulting better stability of the bit. 2.Main cutter are high performance PDC cutters to insure service life of the bit while improving ROP. 3.Cutter exposure is optimized to insure the bit can achieve higher ROP is soft to medium formations. 4.Shock absorbers are designed to make the bit capable of drilling through formations with hard strigers. 5.Hydraulic system of the bit is optimized using dynamic flow pattern simulation technology to enhance cleaning and cooling effects of the bit to effectively prevent bit from balling.

Steel Body PDC Use high-quality steel to make the base material of PDC bit, the surface of the blade weld high-performance wear-resistant materials, the use of computer software for the overall design of three-dimensional PDC BIT, double asymmetric teeth straight blade, medium parabolic crown, long Gage shape structure. Cutting structure using force balance design, unique PDC cutter layout and positioning of the PDC bit to keep a sharp cutting edge in drilling, effectively improve the offensive PDC BIT and drilling speed. The application of fluid dynamics analysis and numerical simulation of hydraulic flow field analysis technology to design, help to improve chip speed drill and anti-balling capacity. Suitable for high compressive strength, with abrasive medium hard to hard formations, such as shale, limestone, anhydrite, sandstone and so on.
