Intwana yePetroleum Drill

Intwana yePetroleum Drill

I-petroleum drill bit idlala indima ebalulekileyo ekwembeni i-oyile, ibe nefuthe elibonakalayo kumgangatho wokomba, ukusebenza kakuhle, kunye neendleko. Iindidi ze-petroleum drill bits ziquka ii-scraper bits, ii-roller cone bits, i-diamond bits, kunye ne-PDC (ii-polycrystalline diamond compact bits). Eli nqaku ligxile kwi-scraper bits.

Amasuntswana e-scraper ayephakathi kwezokuqala asetyenziswa ekugrunjweni okujikelezayo, ukusukela ngenkulungwane ye-19 kwaye zisasebenza kwiindawo ezithile leoli namhlanje. Bagqwesa kulwakhiwo oluthambileyo noluncamathelayo, lunikezela ngesantya esiphezulu sokugrumba oomatshini kunye nobuchule bokungena. Iibhithi ze-scraper zixabiswa kuyilo lwazo olulula, ukuphumelela kweendleko, kunye nokulungelelaniswa kokwenziwa kwesiko kwi-oilfields nganye.

Intwana ye-scraper inomzimba omncinci, iiblades ezikhuhlayo, imilomo, kunye nenkunzi yenkomo. Umzimba omncinci, owenziwe ngentsimbi ephakathi kwekhabhoni, ubonisa iiblades ezidityanisiweyo ze-scraper kunye ne-bullnose kwisiphelo esisezantsi, kunye noqhagamshelo oludityanisiweyo kwincam ephezulu yokuncamatheliswa kumtya wokubhola. I-scraper blades, eyaziwa ngokuba ngamaphiko, zizinto ezibalulekileyo ze-scraper bits.

Iibhithi ze-scraper zihambisa ukusebenza okuphezulu kwiifom ezithambileyo kunye ne-adhesive. Ngexesha lemisebenzi yokomba, ulawulo oluchanekileyo loxinzelelo lokomba kunye nesantya sokujikeleza kubalulekile ukuthintela ukutenxa kunye nokuqhekeka kwe-blade. Ukunikezelwa kwesantya esiphezulu sokomba koomatshini kwiindlela ezithambileyo kunye nesiphumo somthamo omkhulu wokusikwa, kusetyenziswa ulwelo lokomba olunomthamo ophezulu kucetyiswa ukuqinisekisa ukucocwa ngokucokisekileyo komngxuma wequla kunye nokupholisa okusebenzayo kwentwana. Ngaphezu koko, isantya esonyukayo se-peripheral samaphiko e-scraper bit sinokukhokelela ekunxityweni kwe-conical, efuna imilinganiselo enononophelo ukuthintela ukucutheka komngxuma kunye nokutenxa ngakumbi.

Ngaphandle kokusebenza kwabo okugqwesileyo kukwakheka okuthambileyo kunye nokuncamathelayo, amasuntswana e-scraper nawo abonisa inzuzo kwezinye iindawo zophuhliso. Ngokomzekelo, kwiindawo ezinobushushu obuphezulu kunye noxinzelelo oluphezulu, i-scraper bits igcina ukusebenza okuzinzile, ukuqinisekisa ukusebenza ngokukhuselekileyo kunye nokusebenza ngokufanelekileyo. Oku kuguquguquka kuseka i-scraper bits njengokhetho oluyimfuneko ekugrunjweni kwe-petroleum, nokuba kukwi-oyile yendabuko okanye ejongene nemingeni evelayo yamanzi anzulu kunye ne-ultra-deep-deep-ather, egxininisa ixabiso labo elikhethekileyo kunye nokusetyenziswa kwayo.
