Ifektri ye-China PDC bit izohlinzeka ngama-PDC bit angu-12.25 amayintshi anama-blade angu-5

I-PDC bit engu-12.25 intshi enama-blade ama-5 inikeza ukusebenza okuhle kakhulu kokumba uwoyela, igesi, kanye nezimayini. Isakhiwo sayo sama-blade amahlanu sisabalalisa ngokulinganayo umthwalo wokusika, sehlisa ukudlidliza, futhi sithuthukisa ukuzinza, sinciphise ukuguguleka kwamathuluzi futhi sithuthukise ikhwalithi yemigodi. Abasiki be-PDC abaphambili banikeza ubulukhuni obumangalisayo kanye nokumelana nokuguguleka, baqinisekisa impilo ende yamathuluzi kanye nohambo oluncane. Iziteshi zokugeleza ezilungiselelwe zithuthukisa ukuphuma nokupholisa kwama-cuttings, zivimbele ukugoba kwama-bit ezinhlotsheni ezinamathelayo. Lo mklamo uphakamisa izinga lokungena (ROP) kakhulu ezinhlotsheni ezithambile neziphakathi nendawo, unciphisa isikhathi sokumba, futhi wehlisa izindleko ngemitha. Ukumelana okunamandla komthelela kuhambisana nezigaba ezahlukene. Ukusebenza kahle okulinganiselayo, ukuqina, kanye nokuzinza kwenza kube ukukhetha okungabizi kakhulu kumaphrojekthi okumba adinga amandla.
