I-PDC bit eyayisebenzisa ukubhola ioyile/igesi enzulu, ukwembiwa kwemigodi yamatye aqinileyo, ukubhola imithombo ye-geothermal, kunye neeprojekthi zeziseko zophuhliso ezinobukhulu obukhulu.

1. Ukumelana Nokunxiba Okungaqhelekanga Kwiindlela Eziqinileyo Yenziwe nge-tungsten carbide matrix enobunzima obuphezulu, i-bit imelana nokukrala okukhulu kwilitye eliqinileyo (umz., i-granite, i-quartzite) kunye neendawo ezinoxinzelelo oluphezulu/ubushushu obuphezulu (HPHT). Inciphisa ukukrala kwee-bit nge-30%+ xa kuthelekiswa nee-matrix bits eziqhelekileyo, iqinisekisa ubomi obude bokusebenza kwiimeko ezinzima zokubhola.

2. Ukusebenza kakuhle kokubhola kunye nezinga lokugqobhoza eliPhezulu. Isakhiwo sokusika esilungisiweyo esine-PDC cutter layout ephuculweyo kunye ne-back rake angle iphucula ukudibana nezakhiwo zamatye aqinileyo. Ibonelela nge-ROP ephezulu ngama-25-40% kunee-roller cone bits zendabuko, inciphisa imijikelo yokubhola kunye nokunciphisa iindleko zokubhola ngeenyawo.

3. Ukumelana neMpembelelo eNzima kunye neTorque Uyilo lomzimba we-matrix oluqinisiweyo luphucula ukuqina kwesakhiwo, okuvumela i-bit ukuba imelane nokungcangcazela okukhulu kunye nokuguquguquka kwe-torque kwilitye eliqinileyo eliqhekekileyo. Inciphisa umonakalo we-bit kunye nokusilela kwangaphambi kwexesha, inciphisa ukukhubeka rhoqo kunye nexesha elingenzi mveliso (NPT).

4. Umgangatho ochanekileyo weMingxunya kunye nokuzinza kweWellbore Uyilo oluphambili lwe-hydraulics luqinisekisa ukususwa okusebenzayo kweziqwenga, ukuthintela ukuqhekeka nokunamathela kwiindawo eziqinileyo. Lugcina ububanzi bemingxunya kunye nokuma nkqo, lunciphisa ubunzima bokusebenza kwe-casing kunye nokuphucula ukusebenza kakuhle kokugqiba umngxuma.
