Thaum PDC cov khoom muaj ntau qhov zoo, lawv kuj muaj qee qhov tsis zoo:
Nqi: PDC cov khoom yog feem ntau kim dua pem hauv ntej piv rau cov khoom siv rau lub khob hliav qab. Kev siv cov khoom siv hluavtaws pob zeb diamond cutters thiab cov txheej txheem tsim khoom ua tau zoo ua rau cov nqi pib dua.
Tsawg Kev Ua Haujlwm hauv Hard Formations: Txawm hais tias PDC cov khoom ua tau zoo nyob rau hauv ntau qhov kev tsim, lawv yuav tawm tsam hauv cov txheej txheem nyuaj heev lossis abrasive. Hauv cov xwm txheej zoo li no, cov pob zeb hluavtaws hluavtaws tuaj yeem hnav tawm sai dua, ua rau txo qis kev ua haujlwm zoo thiab nce nqi hloov me ntsis.
Vulnerability rau kev puas tsuaj: PDC cutters tuaj yeem ua rau muaj kev puas tsuaj los ntawm kev hloov pauv sai sai hauv cov txheej txheem drilling lossis ntsib cov khib nyiab nyuaj hauv lub qhov dej. Qhov no tuaj yeem ua rau chipping lossis tawg ntawm cov cutters, cuam tshuam rau kev ua haujlwm drilling thiab yuav tsum tau hloov me ntsis ntxov ntxov.
Kev txwv kub: PDC cov khoom muaj qhov kub thiab txias vim yog cov khoom siv hluavtaws pob zeb siv hauv lawv cov kev tsim kho. Thaum qhov kub thiab txias tau ntsib hauv kev sib sib zog nqus drilling, kev ua haujlwm thiab kev ua haujlwm ntev ntawm PDC cov khoom yuav txo qis, ua rau txo qis drilling efficiency thiab me ntsis lub neej.
Complex Design thiab Engineering: Tsim thiab engineering PDC cov khoom yuav tsum muaj kev paub tshwj xeeb thiab kev txawj ntse. Lub complex geometry ntawm cov qauv txiav thiab kev ua kom zoo rau cov kev mob tshwj xeeb tuaj yeem ua rau PDC cov khoom nyuaj rau kev tsim thiab tswj piv rau cov menyuam lub khob hliav qab.
