Wear resistance of teeth of conventional steel tooth cone bit is
not good, tooth shape structure is lack of optimization, which
leads to decrease of average ROP. AMR series steel tooth bit with
high efficiency can solve these problems, with strong wear
resistant teeth and fast ROP, bit can work more stably, which is
more suitable for drilling in soft or middle soft formations with
high rotary speed.
Application of AMR series steel tooth bit with high efficiency is
the best way to solve the problem of increasing drilling speed
in higher part of well.
AMR series steel tooth bit
with high efficiency has strong wear resistant teeth and last ROP
bit can work more stably which is more suitable lor drilling
in soft or middle soft formations.
The size range of AMR
series bit is 8 1/2 - *7 1/2 inch such as 8 3/8, 8 1/2, 8 5/8,
8 7/8, , 9 1/2, 9 7/8, *0 5/8, *1, *1 5/8, *2 1/4, *2 3/4, *3
3/8, *3 1/2, *3 5/8, *4 1/2, *4 3/4, *5 1/2, *6, *7 1/2 and
its IADC code is **7 - **7 (or **5 -
**5).
Optimized structure design of cutter shape is thickened
hardfacing on surface and crest of cutters to enhance
aggressiveness for cutters. Enhanced hardfacing on
leading edge and training edge of cutters improve
wear-resistance of cutters.
