ayini amathuluzi okudoba amafutha?

Ukudoba uwoyela yigama elivamile elisetshenziswa ukuchaza izindlela ezikhethekile ezisetshenziswa ukubuyisela izinto noma izinto zokusebenza emgodini ophansi. Lezi zinto noma okokusebenza okubhajwe embobeni kuvimbela ukusebenza okuvamile ukuthi kuqhubeke. Kufanele zisuswe ngokushesha ngangokunokwenzeka. Uma imishini ihlala isikhathi eside emgodini, kuba nzima nakakhulu ukuyibuyisela. Amathuluzi okusiza ukususa lezo zinto abizwa ngokuthi amathuluzi okudoba amafutha.

Kungani lezo zinto noma amathuluzi abhajwe emgodini?

Ukwehluleka kokukhathala, okubangelwa ukucindezeleka ngokweqile kuntambo yokubhoboza

Ukungaphumeleli kwempahla yomgodi ngenxa yokugqwala noma ukuguguleka ngokumba uketshezi

Ukuhlukaniswa kwentambo yokubhoboza ngenxa yokudonsa kakhulu ngenkathi uzama ukukhulula okokusebenza okubhajwe.

Ukuhluleka kwemishini kwezingxenye ze-drill bit

Ukuwisa amathuluzi ngengozi noma ezinye izinto ezingabhoboki emgodini.

Ukunamathela kwepayipi lokubhoboza noma i-casing

Umhlangano Ojwayelekile Wokudoba

I-Overshot - Ibhampa yokudoba engaphansi - DC - imbiza yokudoba - DC's - Accelerator - HWDP.

Lokhu kulungiselelwa kungase kulungiswe ukuze kuhambisane nezimo ezithile.

Inani lamakholomu okubhola lincike kulokho okutholakalayo nokuthi yini okungenzeka ukuthi isivele iphansi-umgodi. Ukuze kuzuzwe umphumela omkhulu we-jarring, inani lamakholola okubhoboza kumhlangano wokudoba kufanele lilingane nenani lalawo asevele ephansi.-umgodi.

Nge-accelerator emhlanganweni wokudoba, inani lamakholomu okubhola lingancishiswa kakhulu. I-accelerator inconywa kukho konke ukudoba.

Ijoyinti lokuphepha akufanele lisetshenziswe ngenkathi kudotshwa, ngoba amalunga okuphepha angase abe yiqhwa lapho efakwa emanzini. Nokho, i-op egcwelei-ening safety joint (ijoyinti ledrayivu elenzelwe i-jarring) lingasetshenziswa uma intambo yokuwasha isetshenziswa. Lokhu kuvulwa okugcwele kokuphepha okuhlangene kusetshenziswa ngaphansi komhlangano ojwayelekile wokudoba ukuze abasiki bangaphakathi basebenze lapho intambo yokuwasha inamathela futhi kufanele ihlehliswe.

Imidwebo enemininingwane yomhlangano wokudoba izokwenziwa futhi igcinwe ngaphambi kokuthi umhlangano uqhutshwe. Amathuluzi anama-ID akhawulelwe ngeke asetshenziswe.

Uma amazinga okungena ayephezulu ngesikhathi kwenzeka i-twist, zungeza imbobo ihlanzeke ngaphambi kokuyikhipha. Also, zungeza njengoba kudingekile ngaphambi kokubambelela ezinhlanzini futhi ugweme ukumaka phezulu kwenhlanzi ngaphambi kwesikhathi.

Ukubambana okuvunguzayo kufanele kusetshenziswe noma nini lapho kungenzeka khona esikhundleni sokubamba ubhasikidi kuqhume i-overshot ngemva kokuba inhlanzi isigaywe, besesebenzisa isandiso ukuze ukubambana kubambe ipayipi elingagayiwe.

Emgodini ogeziwe uma umhlangano wokudoba ojwayelekile uhluleka ukuthola indawo engaphezulu yenhlanzi, khona-ke imizamo kufanele yenziwe kusetshenziswa ihhuku egobile noma ihuku lodonga.
