  • Optimum Design - PDC BIT/TRICONE BIT/DRILL BITS

    Adopting design with 4 wings, deep inner cone, low density cutters placement, using CFD to optimize hydraulic structure of PDC bits, we designed out a PDC bit 9 1/2’’WS416DR with good effective. From application in site, the ROP and drilling depth was increased 16% at least. This kind of PDC bit solved the bit balling and low ROP problem.

    2018-11-1 · As can be seen in Table 7 and Fig. 10, the optimum bit diameter changes in a range between 7.997 and 8.285 in. This shows that the biggest bit diameter happens in the uncertainty conditions of the economic parameters (BL and HDC) and the smallest occurs in a combination of two technical parameters (uniaxial compressive strength and rock density) and one economic parameter, the hourly drilling …

  • Optimal Design Parameters of a Percussive Drilling

    This paper aims to determine the optimal design parameters for percussive drilling systems considering the bit-rock interaction. First, the motion dynamics of a bit impacted by a dropped piston are modeled by impact stress propagation and a rock-breaking mechanism representing the penetration resistance coefficient and unloading constant.
