    Optymalizacja procesu wiercenia narzędziami PDC o średnicy 8 1/2''
    (2009) Rado, Robert; Lubaś, Jan
    Drilling tools with polycrystalline diamonds create great possibilities as far as selection of tools for specific drilling conditions are concerned. Their application is effective and contributes to increasing drilling coefficients. The recent design solutions enable efficient work when the weight on the bit is of 20 kN (2 T). With such a law weight on the bit it is possible to make BHA array and protect the drill string against unfavorable vibrations generated by tools operating at higher weights on the bit. The PCD tools may have considerable advancements and footage in optimized mechanical and hydraulic drilling parameters of these tools as well as suitable design of the lower part of the drill string. An attempt was undertaken at optimizing the drilling parameters for PDC 8 1/2'' for drilling operations in the Carpathian For
