HJ metrix body /steel body PDC bit
Part 1,Application:
Part 1,Application:
1,Suit for drilling medium to medium-hard formations.
2,Evolute asymmetrical blade cutter design and balanced bit load so that bit whirl is prevented .
3,Composite gage protection and low torque design improve rate of penetration .
4,CFD hydraulic balance design results in better bit cleaning and cutting removal .
5,Combined utilization of high performance PDC compacts significantly prolongs bit life
Higher nozzle counts and/or fixed ports to best serve cleaning,cooling and cuttings evacuation requirements with available hydraulic flows.Allows for higher flow rates with minimal increase in pump pressure.
Feature:Diamonds are impregnated in the matrix behind the PDC cutters
Benefit:Increased footage drilled in abrasive applications
Part 2.Operation Instructions on Hengji PDC bits
1.Please select the applicable formation and parameters according to the instructions.
2.Selection of the appropriate nozzle according to the hydraulic parameters of the nozzle hole size differential is not too much to prevent erosion of the stream channel.
3.Before the bit running into the well, the user should carefully check the overall appearance and confirm that the serial number on the shank end is the same as those on the packing box and certificate.
4..The required bit operating procedures should be followed. After getting to the bottom hole, the bit must be running in slowly with lighter bit weight(WOB: 5-15KN, RPM: 60r/min) for 1/2 hour and then drilling ahead with normal WOB.
5.If abnormal damage(s) of the bit occurred, please contact the company and the packing box, inspection certificate, original performance records as well as the failure bit(with nozzles on ) should be kept for our view, or we are not responsible for it.
