High Quality Drills To Drill Water Wells/Steel Tooth Drill Bits
Introduction
There are a normal three cone Bits that have been used for drilling
Oil wells for decades. There are many types to use from soft
formation /low compressive strength to extremely hard and abrasive
formation, from roller bearing air cooled to sealed roller bearing,
and to sealed friction bearing with gage protection. For ordering
you must specify IDAC, three digit no. the fist digit specify
formation, second digit the type of Bit and the third digit is
allocated to seal type and off course the size of Bit required
Suitable Formation |
IADC CODE | Rock Formation | WOB KN/mm | PRM(r/min) |
115 | Extremely soft formations with low compressive strength and high
drillability, such as clay, mudstone, chalk. | 0.3~0.75 | 180~60 |
117 | Extremely soft formations with low compressive strength and high
drillability, such as clay, mudstone, chalk. | 0.35~0.8 | 150~80 |
127 | Soft strata with low compressive strength and high drilla-bility,
such as mudstone, gypsum, salt rock, soft shale, and soft
limestone. | 0.35~0.9 | 150~70 |
217 | Soft to medium strata with low compressivestrength, such as medium
soft shale, medium softlimestone, medium soft sandstone, and soft
strata with hard intercalation. | 0.4~1.0 | 100~60 |
Features
1. High strength, high elasticity, high temperature resistance,
high wear resistance.
2. High precision metal seal.
3. Lock the balls to adapt to high speed.
4. Using high-strength and high-toughness carbide teeth,
Used in
Tri-cone bit is a decelerating bit. It is based on the fact that
the speed of the cone is less than the speed of the bit. It is
suitable for sidetracking of old wells and deepening of small
boreholes under high speed and high drilling pressure.
