Ingxenye emaphakathi yesondo A
Idizayini ye-ROP ephakeme ekubunjweni kwezakhiwo ezijulile nezilukhuni, i-PDC drill bit ihlale ibhola kusuka phansi kuya phansi ngqo ngokugijima okuncane noma ngisho okukodwa, kusindisa isikhathi esikhulu nezindleko.
Ehlukile ku-tricone bit, i-PDC drill bit isebenza nge-WOB ephansi kepha i-Higher RPM, ngakho-ke imvamisa isebenza ngemoto eyehlayo ukuthola isivinini sokujikeleza.
Ukusebenza kwe-PDC drill bit kuncike kakhulu kuma-PDC cutters, sinikeza isisombululo esiyingqayizivele kuzidingo ezithile ezakhiweni ezahlukahlukene.
Incazelo yomkhiqizo
Lapho ingxenye emaphakathi yesondo ligingqika odongeni lomthombo, ukuqhuma kobubanzi be-bit kuncishiswe kakhulu ngenxa yokuxhaswa kwama-spokes.
Ukusika kubushelelezi, impilo yabagawuli yinde, futhi umgodi wokujula ujwayelekile; abasiki kuma-spokes bangakhuphula nekhono lokusika ohlangothini.
Futhi ngaphandle kokukhulisa inani lamabhande, isivinini sokubhola okuqondisayo kwebhithi singakhuphuka ngenkathi kuqinisekiswa ijubane lokubhola.
Insimbi enamandla kakhulu ye-alloy kanye ne-accounting eyinkimbinkimbi yokuqinisekisa ukuqinisekisa ukuphepha nokuthembeka kwebhola lokubhola;
Ukuphuma kwe-chip ebanzi nokujulile nokuklanywa kwe-hydraulic kungavimbela ngempumelelo udaka oluncane.
