I-Petroleum Drill Bit

I-Petroleum Drill Bit

I-petroleum drill bit idlala indima ebalulekile ekumbiweni kukawoyela, ibe nomthelela omkhulu kwikhwalithi yokumba, ukusebenza kahle, kanye nezindleko. Izinhlobo ze-petroleum drill bits zifaka ama-scraper bits, ama-roller cone bits, ama-diamond bits, nama-PDC bits (ama-polycrystalline diamond compact bits). Lesi sihloko sigxile kuma-scraper bits.

Ama-scraper bits ayephakathi kwezokuqala asetshenziswa ekubholeni i-rotary, kusukela ngekhulu le-19 futhi asasebenza kwezinye izindawo zikawoyela namuhla. Zihamba phambili ekwakhiweni okuthambile nokunamathelayo, okuhlinzeka ngesivinini esiphezulu sokumba ngomshini namandla okungena. Ama-scraper bits abaluleke kakhulu ngokuklama kwawo okulula, ukuphumelela kwezindleko, nokuvumelana nezimo zokwenziwa ngokwezifiso ezindaweni zamafutha.

I-scraper bit inomzimba omncane, ama-scraper blades, ama-nozzles, ne-bullnose. Umzimba omncane, owenziwe ngensimbi ye-carbon-carbon ephakathi, uhlanganisa izindwani ezishiselwe kanye ne-bullnose ekugcineni okungezansi, nokuxhunywa okunentambo ekugcineni okunamathiselwe kuntambo yokubhoboza. Ama-scraper blades, awaziwa nangokuthi amaphiko, ayizici ezibalulekile ze-scraper bits.

Ama-scraper bits aletha ukusebenza okuphezulu ekwakhekeni okuthambile nokunamathelayo. Ngesikhathi sokumba, ukulawula okunembile kwengcindezi yokumba kanye nesivinini sokuzungeza kubalulekile ukuze kuvinjwe ukuchezuka nokuphuka kweblade. Uma kubhekwa isivinini esikhulu sokumba ngomshini ekubunjweni okuthambile kanye nomphumela wevolumu enkulu yokusika, kuyanconywa ukusebenzisa uketshezi lokumba olunevolumu ephezulu ukuze kuqinisekiswe ukuhlanzwa okuphelele kwe-borehole kanye nokupholisa okusebenzayo kwengcezu. Ngaphezu kwalokho, ijubane elikhulayo le-peripheral lamaphiko e-scraper bit lingaholela ekugugeni kwe-conical, okudinga izinyathelo ezicophelela ukuvimbela ukuncishiswa kwemigodi kanye nokuchezuka okuqhubekayo.

Ngaphandle kokusebenza kwabo okuhle kakhulu ekwakhekeni okuthambile nokunamathelayo, ama-scraper bits nawo akhombisa izinzuzo kwezinye izindawo zentuthuko. Isibonelo, ezindaweni ezishisa kakhulu nezinomfutho ophezulu, ama-scraper bits agcina ukusebenza okuzinzile, ukuqinisekisa ukusebenza kokumba okuphephile nokusebenza kahle. Lokhu kuguquguquka kusungula izingcezu ze-scraper njengenketho ebalulekile ekumbiweni kwe-petroleum, noma ngabe ukukha uwoyela ongokwesiko noma ekubhekaneni nezinselele ezivelayo zezifunda ezijulile namanzi ajulile, kugcizelela ukubaluleka kwazo okuyingqayizivele namandla azo okusebenza.
