Ke Hobane'ng ha Tungsten e le ea Bohlokoa Hakaale bakeng sa Ts'ebetso ea ho Cheka Oli le Khase?

Bohlokoa ba tungsten (haholo-holo tungsten carbide) ho chekeng peterole bo ka tšoantšoa le hore ke eona"Meno a indasteri"ea ts'ebetso. E fana ka lisebelisoa tsa ho cheka kabokhoni ba ho etsa qeto ea ho roba lefika ka mokhoa o tsoelang pele, ka katleho le ka mokhoa o tšepahalang ha ba ntse ba itšireletsa tlas'a maemo a feteletseng a jeolojiSenamotsoako o phethahetseng oa ho thatafala, ho tiea, ho hanyetsa mocheso o phahameng, le ho hanyetsa ho tsofalae etsa hore e be thepa ea bohlokoa ka maano le e ke keng ea nkeloa sebaka hona joale. Ke ka lebaka leo ho feto-fetoha ha litheko tsa tungsten ho amang indasteri eohle ea ho cheka peterole ka kotloloho.

Ka tlase ke tlhahlobo e qaqileng ea mabaka a mantlha:

I. Boitsebiso ba Bohlokoa bakeng sa ho Hlōla Maemo a Feteletseng a Ts'ebetso

Ho cheka peterole—haholo-holo lilibeng tse tebileng, lilibeng tse tebileng haholo, lilibeng tse bataletseng tsa khase ea shale, le ho cheka lebōpong la leoatle—ho tobane le liphephetso tse tharo tse kholo tse “feteletseng”:

1. Khatello e Feteletseng le Thempereichara: Botebong ba lik'hilomithara tse 'maloa, mocheso o ka feta 200°C, ka likhatello tse fihlang libakeng tse makholo tsa sepakapaka.
2. Ho Hlaha ho Feteletseng: Dikarolo tsa ho phunya di lokela ho phunyeletsa dibopeho tse thata le tse kgopameng (mohlala, granite, lejwe le thata, lejwe la lehlabathe la quartz).
3. Tšenyo e Feteletseng: Metsi a ho tjheka a ka ba le dikhemikhale tse senyang, metsi a letsoai le kgase ya hydrogen sulfide.

Tharollo ea Tungsten: Tungsten Carbide Hard Alloy

• Ho se Tšoane le ho Hanyetsa ho Tloha: Carbide ea tungsten e latela daemane feela ka thata empa e fana ka khanyetso le ho tiea ho hoholo ha e bapisoa le daemane. Sena se e lumella ho sebetsa joalo ka "meno a indasteri," e ntse e phunya lefika ka lebelo le phahameng le mojaro o boima, ka bophelo ba ts'ebeletso bo bolelele ka makhetlo a mashome ho isa ho a makholo ho feta tšepe e tloaelehileng.
• Ho Chesa ho Hlollang Haholo: E boloka thata e phahameng esita le mochesong o phahameng (ho fihlela ho ~1000°C), ho fapana le litšepe tse ngata tse nolofatsang le ho hloleha ka potlako.
• Botsitso bo Botle ba Lik'hemik'hale: E hanela ho bola ho tswang maro a ho tjheka le maro a ka tlasa lefatshe.

II. Litšebeliso tsa Bohlokoa ho Mekhoa ea ho Cheka

Tungsten (haholo-holo ka sebopeho sa tungsten carbide le li-alloy tsa tungsten) ke karolo ea bohlokoa ea likarolo tse ngata tsa bohlokoa tsa ts'ebetso ea ho cheka:

1. "Meno" le Meeli e Sehang ea Likotoana tsa ho Sebetsa:

• Likotoana tsa Khoune: “Meno” a kentsweng khouneng ka nngwe a entswe haholo ka tungsten carbide. Ke wona mola o ka pele lefikeng le kopanang le le pshatlehang.
• Li-Bits tse Sehang tse Tsitsitseng: Leha dikotwana tsa PDC (Polycrystalline Diamond Compact) di sebedisa disehi tsa taemane bakeng sa ho kuta sebaka se seholo,li-trimmer tsa gauge, meno a serethe, le li-insert tsa reinforcement libakeng tse bohlokoahangata li itšetleha ka tungsten carbide ho thibela ho tsofala 'meleng oa karolo.
• Likotoana tse Ikhethang: "Di-Bits tse Kentsweng ka Taemane" tse sebediswang dibopehong tse thata ka ho fetisisa di na le dikarolwana tse ngata tsa tungsten carbide ka hara matrix, tse sebetsang e le thepa e kgopang le sebopeho sa tshehetso.

1. Likarolo tse Hanelang ho Tloha bakeng sa Lisebelisoa tsa Bohlokoa:

• Lisebelisoa tsa ho theola: Bokaholimo ba kantle ba disebediswa tsa MWD/LWD, di-stabilizer, le di-reamer hangata di thatafatswa ka dikarolwana tsa tungsten carbide kapa di tlatsitswe ka di-insert tsa tungsten carbide ho hanela ho tsofala ho hoholo ho tswang leboteng la metsi.
• Likarolo tsa Khoele ea ho Cheka: Meqhaka ea ho roala manonyeletsong a lisebelisoa tsa phaephe ea ho phunya le phaephe ea ho phunya e boima e koahetsoe ka tungsten carbide ho fokotsa khohlano le ho tsofala haholo khahlanong le sekoahelo, ho sireletsa li-tube tse turang.

1. Thepa ea Boima bo Phahameng:

• Litšepe tse kopantsoeng tsa Tungsten-nickel-tšepeli sebelisoa bakeng sa boima ba lisebelisoa tsa ho ngola ka nepo joalo ka MWD/LWD.ho ba le sekgahla se phahameng (≈18 g/cm³)e dumella bongata bo boholo libakeng tse koaletsoeng, e tsitsisa lisebelisoa ka katleho le ho netefatsa ho fumanoa ha data ka nepo.

III. Melemo e Tobileng—Lebaka Leo e “Ke keng ea Phetoloa” ka Lona

1. Bokgoni bo Ntlafaditsweng ba ho Cheka: Likarolo tsa tungsten tse thata le tse sa tsofaleng li lebisa hosekhahla se phahameng sa ho kenella (ROP)lefilimi e telele ka ho matha hanyane, e fokotsang ka ho toba nako ea kaho ea seliba.
2. Polokeho le Botšepehi bo Tiisitsoeng ba Ts'ebetso: Ho hloleha ka tshohanyetso ha karolo kapa sesebelisoa se theohelang ka tlase ho ka fella ka mesebetsi e jang tjhelete e ngata ya ho tshwasa ditlhapi kapa esita le tahlehelo ya seliba. Botshepehi bo ikgethang ba dikarolo tsa tungsten ke senotlolo sa ho tswela pele ha tshebetso.
3. Litšenyehelo tse tlase tsa Kakaretso: Leha thepa ea tungsten e le theko e boima, melemo—nako e fokotsehileng ea ho khoptjoa bakeng sa liphetoho tsa bit, sekhahla se tlase sa ho hloleha, le karolo e phahameng ea ho cheka ka kakaretso—e lebisa litšenyehelong tse tlase haholo ka mithara nakong eohle ea bophelo.
4. E nolofalletsa Ts'ebetso e Feteletseng: Ntle le di-alloy tse thata tse thehilweng ho tungsten, ho tjheka didiba tse ngata tsa kajeno tse fetang botebo ba dimithara tse 5,000 (didiba tse tebileng/tse tebileng haholo) le dijiometri tse rarahaneng tsa didiba ho ne ho ke ke ha kgoneha ka botekgeniki kapa moruong.
