pressure and high drilling speed. So, this kind of bits is widely used in coal mining and oil drilling [1-2]. In the drilling process, Wang et al  investigated the change of interaction between the cutting teeth and coal for the PDC by the finite element simulation method, and got the
that of the roller cone bit. Although PDC bits were used extensively throughout a range of drilling environments, in certain drilling applications, PDC bit perfor-mance pales in comparison to that of roller cone bits. For example, hard carbonates and abrasive sandstones can be problematic for any bit. In such formations, PDC bits tend to drill at a
08-08-2022· PDC drill bits. Polycrystalline diamond materials, for use in polycrystalline diamond compact (PDC) bits, are one of the most important material advances for oil drilling tools in recent years. Fixed-head bits rotate as one piece and contain no separately moving parts. When fixed-head bits use PDC cutters, they are commonly called PDC bits.

· Design of high quality PDC drill bits is necessary to perform MWD directional drilling for underground coal mine. Relatively deepened analysis was carried out here from the structural parameters to the type selection of cutting teeth of PDC drill bits. φ96 mm matrix-body PDC drill bit for directional drilling was developed followed by field tests, for which four branch holes were dilled.
PDC cutters (Polycrystalline Diamond Composite) are consist of polycrystalline diamond layer sintered with tungsten carbide substrate under ultra-high temperature and pressure. PDC cutters are widely used for petroleum and oil field PDC bit, geological PDC exploration bits, gas exploration bits, PDC coal mining drill bits. PDC is mainly
coal, and shale. The formations also have a high unconfined compressive strength (UCS) ranging from 14,000 psi to 24,000 psi. The alternating lithologies and large UCS variation resulted in PDC cutter damage and accelerated wear, reducing ROP and driving up field development costs. To improve drilling efficiency and wellbore quality, the operator needed a PDC bit with durable cutters capable

· The Third Character Of IADC PDC Drill Bit Codes. As a general rule, large PDC cutters sizes (19mm to 25mm) are more aggressive than small cutters. However, they may increase torque fluctuations. Smaller PDC cutters sizes (8mm, 10mm, 13mm and 16mm) have been shown to drill at higher ROP than large cutters in certain applications. One such application is limestone for example.
