Durable carbide drill bit for gas water well

Product Picture





1.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. 

2.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.

 3.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 O-ring   provides adequate sealing for bearing durability.

Tricone bit is Widely used in borehole water well drilling,oil,gas well and mining projects.

Cautious :

1. To keep the mud clean, prevent the impurities from blocking the drill bit port., and affect the use of the drill bit.

2. Drill down to control the speed and prevent the sudden stop, and make the roller bit better.

3. Keep the two pumps in good condition.

4. Pay attention to the drill bit and prevent the drill bit slipped.

5. Adjust the drilling parameters in time when encountering a bad drill or bouncing drill.

6. Before drilling the cone bit, circulate for about 10 minutes, with 1-2 tons of drilling for about 0.5 meters, and gradually pressurize to 6-8 tons of drilling. The drilling is uniform speed to prevent the sudden damage of the teeth.The drill pressure generally is not more than 10 tons. When you are slow to drill, we should see clearly, if it is because of the reason for the interlayer to be patient, do not blindly add pressure.
