8-1/2"PDC Drilling Bit Oil Well Drilling Diamond Bits with Low Prices for petroleum-equipment-machinery drilling tool
The PDC bit's compact cutting structure just utilizes the mechanical property of rock, and uses the efficient shearing way to break the rock, thereby achieving the purpose of fast drilling. When PDC bit in a formation with soft to intermediate hardness, the compact cutting teeth overcome the formation stress enter the formation and slide forward under the effect of WOB and torque, and the rock is broken along its shear direction under the action of cutting and plastic flow is produced. The cuttings produced by cutting are in large pieces, which are then brought by the mud jetting out from nozzle to the annulus between the drill bit and the borehole wall, are transported out of the well.

1. Check whether the last bit used has any damage, cutter dropping, diameter reduction, etc., make sure there is no cutter and other hard articles of cemented carbide or steel at the bottom of the well after the last use of the bit, and clean the bottom of the well if necessary.
2. Check whether there is any abnormality in the cutters of the drill bit, whether there is O-ring in the nozzle hole, and install the nozzle as required.
3. Clean the bit male or female thread and apply thread oil.
4. Install the unloader on the drill bit and lower the drill string so that it comes to contact with the male or female thread and make up.
5. Put the drill bit and the unloader into the turntable bushing, and then tighten the screw thread according to the recommended torque value.
