I-PDC Cutter ye-Oli kunye neGesi yoKwemba

Kwinkqubo yophuhliso lomntu, izigidi zezixhobo ziye zasetyenziselwa ukwenza imingxuma, kodwa kukho enye into elawulayo yonke. Ngomzuzu wokugrumba, olona hlobo luxhaphakileyo lwe-oyile kunye ne-gas drill bit namhlanje yi-PDC drill bit. Kudala yaziwa ukuba ukucheba yeyona ndlela isebenzayo yokusilela kwiintlobo ezininzi zeetokhi. Kodwa uninzi lwelo xesha, izinto zokusika zemathiriyeli ezifumanekayo ukusika ilitye zazincinci kakhulu okanye ziya kuguga ngokukhawuleza ukuba zigrumbe ngokwezoqoqosho, emva koko kwafika iPDC.

Indawo ekugxilwe kuyo ye-PDC bit yi-polycrystal kunye ne-diamond cutters, apho ifumana khona igama layo. Abasiki badla ngokuba ziisilinda ezinobuso obunqunqiweyo bedayimani emnyama eyenziwe ngumntu, eyenzelwe ukuxhathisa impembelelo yokurhawuka ngokugqithisileyo kunye nobushushu obuvela ekubhobhozeni ematyeni. Umaleko wedayimane kunye ne-substrate ifakwe phantsi koxinzelelo oluphezulu kunye nobushushu obuphezulu. Idayimani ikhuliswe kwi-carbide substrate, ayigqunywanga. Zihlanganiswe ngokuqinileyo. Izisiki zePDC zisetyenziswa phantse kuzo zonke izicelo ezibandakanya ukombiwa kwamandla e-geothermal, imigodi, iqula lamanzi, ukugrumba irhasi yendalo, kunye nokwembiwa kwe-oyile.

Abasiki bePDC bahlelwe kwi-3d geometry ebizwa ngokuba yisakhiwo sokusika. Isakhiwo sokusika sinokubonakala silula, kodwa ngokuqhelekileyo sisona nxalenye yoyilo oluncinci kwaye ngokuqhelekileyo luqhuba ukusebenza kwento encinci. Ukuze i-PDC bit isebenze ngokuthembekileyo, isakhiwo sokusika kufuneka sihlale sinjalo. Ngenxa yesi sizathu, i-cutters ivame ukulungelelaniswa kwimigqa, evumela ukuba isakhiwo sokusika sibanjwe kunye ngamacangci amakhulu.

Imizimba ye-PDC bits yonke yenziwe ngentsimbi kuqhagamshelo oluphiniweyo, kunye nokutshintshela kwinto ehlanganisiweyo ye-tungsten carbide kumphezulu ongaphandle. Imizimba encinci yimatrix okanye intsimbi ngokuxhomekeke kwindlela eyenziwe ngayo kunye nokuba ingakanani i-tungsten carbide esetyenziswayo. Amasuntswana ePDC anokuyilwa ngokudityaniswa phantse okungapheliyo kwezinto eziguquguqukayo eziguqulelwe kwiimfuno ezizodwa ezahlukeneyo kunye nokutshintsha izicelo zokomba. Namhlanje, ngaphezulu kwama-70% amasuntswana agrunjiweyo asetyenziswa ekugrunjweni kwe-oyile nerhasi ziiPDC. Ngelixa uyilo lwebit lubalulekile, akukho bit yePDC inokusebenza ngaphandle kwe-PDC cutters.

I-ZZbetter igxile kwi-PDC cutter iminyaka engaphezu kwe-15. Ubume be-zzbetter PDC Cutter ibandakanya:

1. Umsiki wePDC oMcaba

2. Iqhosha lePDC elingqukuva

3. Iqhosha leParabolic PDC, iqhosha langaphambili

4. Iqhosha leConical PDC

5. Abasiki bePDC zesikwere

6. Abasiki be-PDC abangaqhelekanga

Ukuba unomdla kwi PDC cutters kwaye ufuna ulwazi oluthe vetshe kunye neenkcukacha, UNGAQHAGAMSHELANA NATHI ngefowuni okanye ngeposi ekhohlo, okanye SITHUMELE MAIL emazantsi ephepha.
