Ukuqhuba Reamer
Uyilo lwe-ROP ephezulu xa kusombiwa ubunzulu kunye nobunzima, i-PDC yokomba isoloko iqhelana ukusuka emhlabeni ukuya ezantsi ngokuthe ngqo nangaphantsi okanye kwinto enye, ukugcina ixesha kunye neendleko.
Umahluko kwi-tricone bit, i-PDC drill bit ibaleka nge-WOB esezantsi kodwa i-RPM ePhakamileyo, ke ihlala isebenza ngeemoto ezantsi ukuya kwisantya esijikelezayo.
Ukusebenza kwe-PDC drill bit kuxhomekeke kakhulu kubasiki be-PDC, sinika isisombululo esikhethekileyo kwiimfuno ezithile kulwakhiwo olwahlukeneyo.
I-PDC reamer sisixhobo esisebenzayo sokugrumba uthambo oluphakathi nolukhuni. Uyilo kunye nentloko yesikhokelo edibeneyo yenza ukuba umsebenzi we-reamer usebenze ngakumbi.
I-PDC reamer yenzelwe udongwe oluthambileyo, i-shale, i-shale ephakathi kunye nelitye lekalika, kwaye isebenza ngakumbi kulwakhiwo oludibeneyo oluhlangabezana neengxaki ezixineneyo. Umbhobho onokuwutshintsha unokuqhubeka nokucoca ubume bokusika kwe-reamer, enokucoca kwakhona ukusika kwiqula ngexesha elifanelekileyo, ukuphucula i-ROP kunye nemifanekiso.
Isakhiwo sayo sokusika se-PDC silungele ukwakheka okuhlukeneyo. Ubungakanani bereamer bubanzi. Ilungele ubungakanani obahlukeneyo bokusebenza kwakhona kwequla. Uyilo lomzimba oluphakamileyo linokubuphucula ngokufanelekileyo ubomi bokusetyenziswa kunye neenyawo.
Kwimisebenzi yokugrumba ngokuthe tyaba, ulwakhiwo olukhethekileyo lwe-reamer lwenza ukuba umngxuma uhle kwaye uzinze. Uyilo oluyingqayizivele lwefiliti luyakucoca ngokukhawuleza ukusika kunye nokugrumba ngokukhawuleza phantsi kwetorque encinci kunye noxinzelelo.
Abathengi banokukhetha abagawuli abafanelekileyo ngokuhambelana neendlela ezahlukeneyo.
