I-Drill Bit ekhulelweyo
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.
Intshayelelo:
I-Diamond Bit ekhulelweyo ineCylindrical blade blade enamazinga aphezulu okungena kwiindawo ezinzima kunye nezomeleleyo zokunxibelelana kweplastiki.
Iimbonakalo
Uyilo 1.Thagethi:Inoyilo olukhethekileyo lokucinezela okuphezulu kunye nokubumba okungafunekiyo. Ilungele i-denser shale kunye ne-sandillaceous sandstone, kunye ne-quartz sandstone ene-abrasiveness ephezulu, ilitye le-sandstone kunye ne-strate interlaced strata zifanelekile.
2.Uhlobo olulodwa lwangaphakathi lwecone: I-geometry ekhethekileyo kunye nolungelelwaniso lwangaphakathi lwe-drill bit luphucula ukusebenza kokusika kwiziko le-drill bit ukwandisa ubomi bonke be-drill bit.
Itekhnoloji
1 Ifomula eyahlukileyo yematriki: Ifomula yomgubo we-matrix onamalungelo epropathi enomgangatho ophezulu wokuqonda kunye nobuchwephesha bokucoca phambili obwenziweyo benze ukuba iipropathi zoomatshini zifike kwinqanaba eliphezulu lehlabathi.
2.Uyilo lwejelo elibanzi nelinzulu lokuhamba: Umjelo wobubanzi obubanzi kunye nobunzulu bokuhamba okunenzuzo kuluncedo ekucoceni nasekuhambiseni izithole kunye nokuthintela ibhola encinci.
