I-Drill Bit ekhulelwe
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.
Isingeniso:
I-Diamond Bit ekhulelwe inebhande lamazinyo le-Cylindrical elinamazinga aphezulu wokungena ekubunjweni okuqinile nokunamandla kokuxhumana kwepulasitiki.
Izici
Umklamo we-1.Inomklamo okhethekile wamandla aphezulu wokucindezela nokwakheka okuluhlaza. Ifanele i-denser shale ne-sandillaceousous sandstone, futhi i-quartz sandstone ene-abrasiveness ephezulu, udaka lwensimbi nolwelwe lwe-sandstone olufaneleke kakhulu.
2. Isakhiwo esiyingqayizivele sesigaxa sangaphakathi: I-geometry eyingqayizivele nokuhlelwa kwesigaxa sangaphakathi se-drill bit kuthuthukisa ukusebenza kokusika maphakathi nendawo yokuprakthiza ukunweba impilo yonke ye-drill bit.
Ubuchwepheshe
1 Ifomula ye-matrix eyingqayizivele: Ifomula ye-matrix powder enamalungelo empahla yengqondo ezimele kanye nobuchwepheshe obuphambili bokwenza sintering benze izakhiwo zemishini ye-matrix ukuthi zifinyelele ezingeni eliphakeme lomhlaba jikelele.
2.Ukuklanywa kwesiteshi esibanzi nokujula: I-radial wide and deep flow channel iyasiza ekuhlanzweni nasekuthuthweni kwezisiki futhi ivimbela ukushaya kancane.
