Producing
Cutting Structure
The wear-resistance of the teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for the steel tooth bit.
The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.
The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.
Professional instruments measure the size of each part to ensure accurate control of errors
This can reduce the bearing wear and greatly improve the service life of the bit
Multipe gauge protection with gauge trimmers on the heel of cone,tungsten carbide insert and hardfacing on the shirttail increases gauge holding capability and bearing life.
The inner hole of the cone is welded with anti-friction alloy to improve the anti-seizure ability of the bearing;
The use of highly saturated nitrile rubber O-ring seals, optimized seal compression to improve the reliability of bearing seals
The use of highly saturated nitrile rubber O-ring seals, optimized seal compression to improve the reliability of bearing seals
Application
Application for Oilfield, gas well ,water wells, HDD and construction ,foundation drilling etc
Ⅰ. bit selection
1. Please reading lithology . description and bit records of adjacent wells carefully,and analyzing formation characteristics.
2. Selecting appropriate type in accordance with lithology .
Ⅱ. Preparation before drilling
1.Inspect previous bit for body damage, lost cutters or inserts etc. Make sure there are no any junk on bottom hole, and clean the
bottom hole if necessary.
2.Bit must be handled with care in order not no damage cutters and hard substances.
3.Check if there is any damage on bit cutters and if there any foreign matter inside the bit.
4.Check if installing nozzle is meet requirements, and replace nozzles if necessary.
Ⅲ. Marking up the bit
1.Clean bit threads and apply grease on threads.
2.Fit the breaker to the bit, lower the drill string onto the pin and engage the threads.
3.Locate the bit and breaker in the rotary bushing, and make-up the bit to be recommended torque.Any inquiry please ask us
