Product Description

15 1/2" (393.7mm) IADC537G TCI Tricone Bit For Water Well Drilling,Water Well Drill Bit

 

Description of Tricone Bits:


The tricone drill bit is the most popular drilling bit in the world,it can be widely used for Oil&Gas Drilling,Mining,Water Well,Geological Exploration areas.Our tricone bit divideds into metal sealed drill bit and rubber sealed bit.

 

1. The C-Center jet can avoid the formation of a ball in the bit, eliminate the fluid area at the bottom of the well, accelerate the upward flow of drilling cuttings and improve ROP.

2. High saturation NBR bearings can reduce sealing pressure and improve sealing reliability.

3. The G-Gauge protection improves the measuring ability and prolongs the service life of the bit.

4. Adding a row of teeth between the rear taper and the outflow to trim the borehole and protect the cone.

Optimal test method for drilling parameters:

1. Drill for 5 minutes with initially selected proper WOB and moderate RPM (60~100r/min) and record the ROP (as shown in the table below).

2. Moderately inctease WOB and keep the same RPM and drill under this WOB for 5 minutes and again record the RPO (as shown in the table below).

3. Decrease WOB b the same extent and tepeat step 2.

4. Find the WOB in the tow groups of test than can yield highest ROP.

5. Properly change RPM under optimal WOB and record the ROP (as shown in the table below).

6. Select the RPM at the highest ROP.

7. Set the drilling parameter at the best combination:60KN RPM: 120r/min
