I-PDC bit eyayisebenzisa ukumba uwoyela/igesi okujulile, ukumbiwa kwamatshe aqinile, ukumba imithombo ye-geothermal, kanye namaphrojekthi engqalasizinda enobubanzi obukhulu.

1. Ukumelana Nokugqokwa Okumangalisayo Kwezakhiwo Eziqinile Yakhiwe nge-tungsten carbide matrix enamandla kakhulu, i-bit imelana nokuguguleka okukhulu edwaleni eliqinile (isb., i-granite, i-quartzite) kanye nezindawo ezicindezelayo/ezishisa kakhulu (i-HPHT). Yehlisa ukuguguleka kwama-bit ngo-30%+ uma kuqhathaniswa nama-matrix bits ajwayelekile, okuqinisekisa ukuthi isikhathi eside sokusebenza ezimweni ezinzima zokubhoboza.

2. Ukusebenza Kahle Kokubhoboza kanye Nezinga Lokungena Eliphezulu Isakhiwo sokusika esilungiselelwe kahle esinesakhiwo esithuthukisiwe se-PDC cutter kanye ne-back rake angle senza kube ngcono ukuxhumana nokwakheka kwamatshe aqinile. Ihlinzeka nge-ROP (Izinga Lokungena) ephezulu ngo-25-40% kunezingcezu ze-roller cone zendabuko, inciphisa imijikelezo yokubhoboza kanye nokwehlisa izindleko zokubhoboza ngefithi.

3. Ukumelana Okunamandla Nokumelana Ne-Torque Ukwakheka komzimba we-matrix okuqinisiwe kuthuthukisa ubuqotho besakhiwo, okuvumela i-bit ukuthi imelane nokudlidliza okukhulu kanye nokuguquguquka kwe-torque edwaleni eliqinile eliqhekekile. Kunciphisa umonakalo we-bit kanye nokwehluleka kwangaphambi kwesikhathi, kunciphisa imvamisa yokukhubeka kanye nesikhathi esingenzi nzuzo (i-NPT).

4. Ikhwalithi Eqondile Yemigodi Nokuzinza Kwemigodi Emincane Umklamo we-hydraulic othuthukisiwe uqinisekisa ukususwa okuphumelelayo kwezicucu, ukuvimbela ukugoba nokunamathela ezimweni eziqinile. Ugcina ububanzi bemigodi obuhambisanayo kanye nokuma kwayo, kunciphisa ubunzima bokusebenza kwesikhala futhi kuthuthukise ukusebenza kahle kokuqeda umthombo.
