Introduction
Air or drilling fluid allows the broken rock debris to survive in an upward annulus from the bottom of the hole. As the rotation continues, another tooth contacts the bottom of the hole and generates new rock debris, thus the process is continuous. High quality tungsten carbide blade (TCI) drill bits and milling tooth (MT) drill bits need to be designed to withstand high temperatures and long-term operation, while drilling through soft to superhard formations.
IADC | WOB(KN/MM) | RPM(r/min) | Applicable Formations |
116 117 | 0.35~0.8 | 150~80 | Very soft formations with low compressive strength and high
drillability,such as clay,mudston,chalk etc. |
136 137 | 0.35~1.0 | 120~60 | Soft to mesium soft formations with low compressive strength and
high drillability.such as medium soft shale,hard gypsum,medium soft limestone.medium soft sandstone soft formation with harder nterbeds,ect. |
216 217 | 0.4~1.0 | 100~60 | Medium hard formations with high compressive strength,such as
medium soft shale,hard gypsum,medium soft limestone,medium soft sandstone,soft formation with harder interbeds ect. |
246 247 | 0.4~1.0 | 80~50 | Medium hard formations with high compressive strength,such as
abrasive shale.limestone,sandstone,dolomite,hard gypsum,marble,ect. |
417 437 | 0.35~0.9 | 150~70 | Very soft formations with low compressive strength and high
drillability,such as clay,mudston,chalk,gypsum,salt,soft shale,soft limestone,etc. |
Features
1. High-strength and high-toughness carbide teeth are used to
improve the impact resistance of the teeth and reduce the tooth
breakage rate;
2. The optimally designed tooth row number, tooth number, exposed
tooth height and unique alloy tooth shape give full play to the
cutting ability and cutting speed of the drill bit;
3. Widely used in petroleum exploration, mining exploration,
geothermal wells, hydrological exploration and other fields.
Our company can provide specific solutions according to the actual drilling situation, and customize assembled drill bits of any diameter, including large-diameter machine pile drill bits, different types of drill bits, reaming bits, directional drilling bits, etc.
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.
