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.
