Izingxenye zokumba zemboni yezezimayini
Izingcezu ze-Tricone drillziyizinqumo ezithandwayo embonini yezimayini ngenxa yokuguquguquka kwazo kanye nempumelelo ezimweni ezihlukahlukene zokumba. Lezi zingcezu zokubhoboza zinamakhanda amathathu ayindilinga anamazinyo agxoba futhi agaye idwala njengoba i-drill bit ijikeleza. Izingcezu zokubhoboza i-Tricone zaziwa ngekhono lazo lokusingatha ukwakheka okuhlukene, okuhlanganisa idwala elithambile, eliphakathi nendawo neliqinile. Afanele futhi ukubhola okuqondile nokuvundlile, okuwenza abe yinketho eguquguqukayo yokusebenza kwezimayini.
Hlehlisa izando ezijikelezayo nezinsimbi zokubholangelinye ithuluzi elibalulekile emisebenzini yezimayini. Lolu hlobo lwemishini yokumba luklanyelwe ukuhlinzeka ngokumba okusebenza kahle futhi okungabizi kakhulu ekwakhekeni kwamadwala aqinile. Indlela yokubuyisela emuva ihlanganisa ukusebenzisa isando ukushayela imbobo edwaleni kuyilapho uletha okusikiwe phezulu phakathi nendawo yentambo yokubhoboza. Lokhu kuvumela ukumba ngokushesha kanye nokutholwa kwesampula okungcono, okuyenza ilungele ukuhlola nokukhiqiza ukugaya ezinhlelweni zokusebenza zezimayini.
Izingxenye zokugaya ze-PDCziwuhlelo olusha lwesimanje lwemishini yokumba izimayini. Lezi zingcezu zokubhoboza zihlanganisa izisiki zedayimane ezigxiliswe ebusweni bebhithi ukuze zinikeze ukuqina nokusebenza okuphakeme ezimeni zokumba eziyinselele. Izingxenye zokumba ze-PDC zaziwa ngamanani azo aphezulu okungena nempilo ende, okuzenza zibe ukukhetha kokuqala kokufuna imisebenzi yezimayini. Zisebenza kahle kakhulu lapho kubhobozwa izinto eziqinile ezifana ne-shale, i-limestone ne-sandstone.
Njengomthumeli wokumba wezimayini, kufanele uqonde izimfuneko ezithile zemisebenzi yezimayini ehlukene futhi unikeze uhla lwezingxenye zokumba ukuze uhlangabezane nalezi zidingo. Kungakhathaliseki ukuthi ama-tri-cone bits, izinto ezithinta ukujikeleza okuhlehlayo namabhithi, noma izingcezu ze-PDC, ukuhlinzeka ngamathuluzi okumba ayikhwalithi nathembekile kubalulekile ekwakheni ukwethembana nobudlelwano besikhathi eside nezinkampani zezimayini.
Kafushane, izingcezu zokumba izimayini zidlala indima ebalulekile empumelelweni yemisebenzi yezimayini. Ukuqonda izinhlobo ezahlukene zezingcezu zokubhoboza, njenge-tricone drill bits,hlehlisa ama-circulation impactors nama-drill bits, kanye nezingxenye zokumba ze-PDC, kubalulekile ukuze kuhlangatshezwane nezidingo ezihlukahlukene zokumba zemboni yezimayini. Ngokunikeza uhla olubanzi lwezingxenye zokumba kanye nokugcina unolwazi ngentuthuko yakamuva yobuchwepheshe bokumba, abathumeli bemishini yokumba izimayini bangaba negalelo ekusebenzeni kahle nasekukhiqizeni imisebenzi yezimayini emhlabeni jikelele.
