Notlolla Lekunutu la Bophelo bo Bolelele ba ho Drill Bit le ho cheka kapele!

1. Ho Khetha Mofuta o Nepahetseng oa Leino bakeng saRoller Cone Drill Bits

Ho khetha mofuta o nepahetseng oa leino bakeng salikotoana tsa rolara khouneha se feela ho lelefatsa bophelo ba ts'ebeletso ea biti empa hape e ntlafatsa litefiso tsa ho kenella le ho fokotsa litšenyehelo tsa ho cheka. Khetho ea mofuta oa leino e itšetlehile haholo-holo ka thepa ea 'mele le ea mechine ea lefika, ho kenyelletsa le matla a lona a hatellang, ho thatafala le ho phunya. Ho feta moo, lintlha tse joalo ka bophara ba borehole, bokahare ba metsi, le ts'ebetso ea tekheniki ea mochini oa ho cheka le tsona li lokela ho nahanoa:

① Bakeng sa libopeho tsa majoe a thata:

Hangata ho sebelisoa likotoana tsa ho phunya li-ball-tooth. Likotoana tsena li na le meno a makhutšoane le a teteaneng, a khonang ho mamella khatello e phahameng ea axial, e leng se etsang hore li tšoanelehe bakeng sa ho cheka mafika a thata ka ho fetesisa a bile a khopama.

② Bakeng sa libopeho tsa majoe a bonolo:

Hangata ho sebelisoa likotoana tsa ho phunya leino la wedge. Likotoana tsena li na le meno a malelele le a manyenyane, e leng se etsang hore e be tse loketseng ho cheka ka mafika a bonolo kapa a polasetiki.

Khetho e sa nepahalang pakeng tsa mefuta ena e 'meli e ka lebisa ho se sebetseng hantle. Ho sebelisa likotoana tsa leino la bolo ka har'a rock e bonolo ho ka baka bophelo bo bolelele empa maemo a tlase haholo a ho kenella, a lebisang litšenyehelong tse phahameng tsa ho cheka ka kakaretso. Ka lehlakoreng le leng, ho sebelisa likotoana tsa menoana ka har'a lejoe le thata haholo, le hlabang ho ka etsa hore meno a alloy a onale kapa a robehe kapele. Ka hona, ho khetha mofuta o nepahetseng oa leino ho ntlafatsa haholo ts'ebetso le bophelo bo bolelele.

2. Optimizing Drilling Parameters

Sekhahla sa ho phunyeletsa ha sekoti se susumetsoa ke lintlha tse ngata, ho kenyeletsa le 'mele oa lejoe la 'mele le mochine, khatello ea axial e sebelisoang ho bitana, lebelo la ho potoloha ha sesebelisoa sa ho phunya, torque ea bit, moralo oa leino, palo ea meno a kenyang lefika, le molumo oa moea o hatelitsoeng o sebelisetsoang ho hloekisa sekoti. Har'a tsena, lintlha tsa bohlokoa tse khethollang katleho ea ho cheka ke khatello ea axial, lebelo la ho potoloha, le phallo ea moea bakeng sa ho tlosoa ha li-cuttings:

①Axial Pressure le Bit Life:

Khatello e lekaneng ea axial e bohlokoa ho pshatla lejoe hantle, kaha e tlameha ho hlahisa khatello e lekaneng ea ho hlola matla a khatello ea lejoe. Leha ho le joalo, ho na le mofuta o nepahetseng oa khatello ea axial. Khatello e feteletseng ho feta mefuta ena e ke ke ea eketsa sekhahla sa ho kenella 'me e ka baka ho senyeha pele ho nako kapa ho senyeha ha li-bearings tsa bit kapa meno a carbide.

② Lebelo la Potoloho:

Ka har'a sebaka se itseng, sekhahla sa ho kenella se eketseha ka lebelo la ho potoloha. Leha ho le joalo, lebelo le feteletseng le ka etsa hore ho be thata ho tlosa li-cuttings ho tloha sekoting, e leng se bakang ho robeha ha lejoe la bobeli le ho sisinyeha ho matla, ho khutsufatsang bophelo. Lebelo le nepahetseng le tiisa nako e lekaneng ea ho kopana pakeng tsa meno le lefika bakeng sa ho robeha ha molumo ka katleho. Bakeng sa mafika a thata, lebelo le phahameng la ho potoloha le thibetsoe ka lebaka la ho eketseha ha meroalo ea tšusumetso, e potlakisang ho roala ha meno le li-bearings. Ka lehlakoreng le leng, ka har'a lejoe le bonolo, mokhoa o phahameng oa lebelo le tlaase o sebetsa haholoanyane.

③ Phallo ea Moea le Li-Cuttings:

Bophahamo ba phallo ea moea bo ama ts'ebetso ea hanyane ka kotloloho. Ho eketsa phallo ea moea ka katleho ho hloekisa sekoti, ho ntlafatsa maemo a ho cheka, ho fokotsa ho khathala ha meno, le ho fana ka pholiso e betere bakeng sa li-bearings, ka tsela eo, ho lelefatsa bophelo. Leha ho le joalo, ho hloekisoa ha metsi ha ho itšetlehe feela ka phallo ea moea empa hape le sebaka sa selemo se pakeng tsa phaephe ea ho phunya le lebota la borehole, e leng se laolang lebelo la moea o khutlang. Ho ntlafatsa ho tlosoa ha li-cuttings ho hloka ho leka-lekanya matla a compressor le ho fokotsa tšebeliso ea moea e sa hlokahaleng.

④ Ho Ntlafatsa Tsebo ea Basebetsi:

Basebelisi ba tlameha ho fetola khatello ea axial le lebelo la ho potoloha ho latela liphetoho tsa thepa ea mafika ho tsamaisana le maemo a ho phunya, ka hona ho thibela ho senyeha ho sa lekanang. Ho feta moo, ba tlameha ho latela melaoana ea ts'ebetso:

- Etsa bonnete ba hore sekoti se hloekile ebile ha se na lintho tse tsoang kantle ho naha pele u cheka.

- Boloka rig e tsitsitseng 'me u sebelise lebelo le itekanetseng ha u qala borehole ho qoba ho kheloha, ho ka fokotsang bophelo.

- Sebelisa khatello e tlase ea axial qalong bakeng sa likotoana tse ncha, ho lumella nako ea ho matha, pele e nyolohela maemong a tloaelehileng.

- Kamehla fana ka moea o lekaneng bakeng sa ho tlosoa ha likotoana nakong eohle ea mosebetsi oa ho cheka, esita le ha o hula karoloana ho tsoa mokoting.

- Bakeng sa liboreho tse metsi kapa ha u sebelisa ho thibela lerole la metsi a moea, khetha likotoana tse nang le li-nozzles tse loketseng ho eketsa khatello ea moea ea lehae, ho sireletsa li-bearings.

- Kamehla hlahloba karoloana ka mor'a ho cheka. Mocheso o sa lekaneng oa li-cones o ka 'na oa bontša likanale tse pholileng tse koetsoeng, tse lokelang ho hloekisoa hang-hang.

- Qoba ho sebelisa liphaephe tse kobehileng tsa ho phunya, kaha li baka meroalo e sa lekaneng, e bakang ho senyeha ha sebaka le ho senya karoloana.

- Thibela liphoso tsa ts'ebetso ho qoba ho akhela likotoana ka har'a sekoti kapa ho li beha kotsing ea tšohanyetso.

- Haeba ho cheka ho emisitsoe, fetola li-cones ka letsoho 'me u ntše lithōle ho netefatsa hore ts'ebetso e tsoela pele hantle.

- Sebelisa stabilizer ka holim'a biti ho boloka tepo ea borehole, ho fokotsa ho thothomela, le ho ntlafatsa ts'ebetso ea hanyane.

Li-stabilizers li thusa bohareng, ho thibela ho kheloha ha sekoti, le ho fokotsa ho sisinyeha, ho fella ka ts'ebetso e bonolo, ho fokotseha ha leino, le ho lelefatsa bophelo bakeng sa karoloana le likarolo tsa eona. Li-bits tse nang le li-alloy tse kentsoeng li boetse li matlafatsa khanyetso ea ho roala, ho thibela ho roala pele ho nako holim'a li-stabilizer pads le ho eketsa botsitso le botsitso ka kakaretso.
