9 5/8" 527 golden TCI tricone jz rock drill bits deep water well drilling and milling machine

Product Description

 Advantage :

1. High temperature heat treatment forged alloy steel .

2. Carbide teeth with high strength and toughness work more efficiently

3. Tooth palm lip hard welding surface with hard alloy ,Effectively prevent the drill bit wear and tear work

4. Head OD protection to effectively reduce head wear in abrasive formation and extend bit work

5.Directional jet enlarges lateral flow area and helpful bottom hole cleaning and increase of ROP

6. Lubricating system protection of bearing and seal system of bit extend bit work life

Application

 

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
