HJ tungsten carbide button bits for oil,gas and well drilling

Part 1.Brief introduction
Hengji company keeps track of the international advanced technology, and built a flexible production line of CNC machining centers mainly drill bits, established a perfect quality assurance system, widely used in the production and management of computer application systems and control systems.

Part 2.
series
characteristic
Soft formation TCI tricone bits
The soft formation TCI tricone bits are used to drill low compressive
strength, very soft formations. This bit maximized to use of both conical
and chisel tungsten carbide inserts of large diameters and high projection.
This cutting structure design, combined with maximum cone offset,
results in high bit penetration rates. The deep intermesh of cutter rows
prevents bit bailing in sticky formations.
Medium formation TCI tricone bits
The medium formation TCI tricone bits features aggressive chisel tungsten
carbide inserts on the heel rows and inner rows. This design provides a fast
drilling rate and added cutting structure durability in medium to medium
hard for mations. The HSN rubber O-ring provides adequate sealing for
bearing durability.
Hard formation TCI tricone bits
The hard formation TCI tricone bits can be used to drill hard and abrasive
formations. Wear resistance tungsten carbide inserts are used in the outer
rows to prevent loss of bit gauge. Maximum numbers of hemispherical
shaped inserts are used in all rows to provide cutter durability and long life.
Medium hard formation TCI tricone bits
The medium hard formation TCI tricone bits features robust chisel tungsten
carbide inserts on the heel row and conical on the inner rows. This design
provides a fast drilling rate and added cutting structure durability in medium
to medium hard formations. The HSN rubber Oring provides adequate
sealing for bearing durability.

Part lll.Operation Instructions on Hengji Tricone bit

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.
