    12 1/4 Inch TCI Tricone Drill Bit Water Well , Geothermal Hole Drilling


    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
    1STEEL 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
    2STEEL TOOTH BITS for Medium Formation
    With medium length teeth, closer spaces, to drill unconsolidated limestones, medium sandstones, clay, marls.
    IADC CODES 211 - 224 - 234
    3STEEL 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
    4TCI BITS for Soft - Medium Soft formations
