Product Description
4000meters without repair  PDC bit for water well drilling

high quality PDC drill bit :
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.

Features and Applications
Features1.Which is a matrix body PDC bit using arc-type double rows spiral design with five blades,long parabolic crown structure,the rational allocation of different functions of the small size of the cutters

2.Heavy cutter layout and high wear wide gauge design,effectively improve the PDC bit impact resistant and abrasive.

3.While using a dynamic flow simulation technology to optimize the hydraulic design of the PDC bit.
ApplicationsMedium to medium hard formations with higher compressive strength and good drillability,such as mudstone,limestone,anhydrite,calcareous sandstone,sandstone,etc.
1. Please select the applicable formation and parameters according to the instructions.
2. Carefully check the bits appearance and to check the bits threaded end face,whether the serial number on the box and certificate.
3. Selection of WOB and RPM should be within the limits of the recommended parameters, higher WOB and RPM cannot be used simultaneously.
4. Bottom hole must be clean and bit must not be used for long section reaming.
5. Drilling process must operate smoothly, find that there is Bie jump on abnormal phenomenon, should be timely analysis and take effective measures
6. The bit should be kept indoor with dry and well ventilated conditions at 10-33ºC and kept from sunshine and rain. Stored under such conditions, quality of bit is guaranteed for 3 years.
