Product Details
12 1/4 inch TCI tricone bit, tricone bit, drill bit water well,
geothermal hole drilling
Features:
1. Horizontal well drilling technology is improved continuously, in
which extended reach well drilling technology and multilateral well
drilling technology have been developed rapidly.
2. Our factory follows improvement of drilling technology tightly,
and has developed new type of TD high speed motor bit suitable for
directional well and horizontal well successfully.
3. Work of bit in directional well and horizontal well has been
changed greatly compare with which in straight well, new type of TD
high speed motor bit has the advantages of applying for high rotary
speed, strong gage protection ability and stability, high
reliability, well hydraulic effect and long service life.
4. Others specify
Working condition of the bit in directional and horizontal drilling
applications is quite different than in vertical well drilling .our
factory’s new TD series motor bit features high RPM, Better gage
protection and stability ,higher reliability, excellent hydraulic
effect and longer working life etc.TD bit is suitable for drilling
at 90~300 RPM and is the ideal choice for directional ,horizontal
and horizontal multilateral well drilling applications.
The size range of TD series bit is from 7 7/8 to 12 1/4 inch ,and IADC varies from 117 to 647. for example:8 1/2TD517X.
Tricone bit IADC code and tricone parameters , please refer:
| First Digit | |
| 1 | STEEL TOOTH BITS for Soft Formation |
| Bits that feature long, widely spaced teeth, to drill soft formation such as shales, soft sandstone, clay and all unconsolidated formations. | |
| IADC CODES 111 - 126 - 134 | |
| 2 | STEEL TOOTH BITS for Medium Formation |
| With medium length teeth, closer spaces, to drill unconsolidated limestones, medium sandstones, clay, marls. | |
| IADC CODES 211 - 224 - 234 | |
| 3 | STEEL TOOTH BITS for Hard Formation |
| With short, closely spaced teeth with tungsten carbide hardfacing, for hard and abrasive formations such as sandstones, dolomite, hard limestone and granite. | |
| IADC CODES 311 - 314 - 321 | |
| 4 | TCI BITS for Soft - Medium Soft formations |
| 5 | Features large chisel-shaped tungsten carbide inserts to provide the highest penetration rates in the softest formations such as shales, clays, limestone and sands. |
| IADC CODES 437 - 517 - 527 | |
| 6 | TCI BITS for Medium Hard - Hard formations |
| Effective in a variety of formations with higher compressive strength such as hard limestone, sandstone, dolomite and other formations with high abrasive quality, hard streaks and broken formations. | |
| IADC CODES 617 - 627 - 637 | |
| 7 | TCI BITS for Hard and abrasive formations |
| 8 | With hemispherical tungsten carbide inserts. To optimize penetration rate in hard and abrasive formations such as granites, basalts, quartzite and chert. Drilling weight of 3 ± 4 tons per inch of diameter should be applied. |
| IADC CODES 732 - 737 - 837 | |
| Second Digit | FORMATION |
| 1 | 1, 2, 3 and 4 are further breakdown of formation with 1 being the softest and 4 the hardest. |
