Ke Hobane'ng ha Mokotla oa Oli le Khase o sa khone ho etsa ntle le li-alloys tse thata?

Ha ho lekoa mehloli ea oli le khase botebong ba Lefatše, likotoana tsa ho phunya motsoako o thata li fetoha sesebelisoa se hloahloa sa batho ntoeng e khahlano le mafika a thata, e leng tiiso e tiileng bakeng sa leano la China.

Sebakeng se hōle sa Tarim Basin, seliba sa Yuejin 3-3XC sa "Deep Earth No. 1" se se se fetisitse botebo ba ho phunya ba limithara tse 10,000. Sebaka sena, ka maemo a sona a rarahaneng haholo a jeoloji, se beha litlhoko tse thata ho lihlahisoa tsa liboro. Se hlolang tikoloho ena e thata ke "meno a tšepe le mehlahare ea tšepe" e entsoeng ka li-alloys tse thata.

I.  Mathata a Tebileng a Lefats'e, Mathata a ho Epa

Ha lipatlisiso tsa oli le khase tsa China li ntse li tsoela pele ho ba likarolo tse tebileng le tse tebileng haholo, masimo a oli a tobane le maemo a feteletseng a khetholloang ke "li-ultras tse tharo le tse phahameng" - mocheso o tebileng haholo, o phahameng haholo, khatello e phahameng haholo le sebabole se phahameng.

Tlas'a maemo a joalo, li-drill tse tloaelehileng li thatafalloa ho sebetsa. Lisebelisoa tsa khale tsa ho cheka li senyeha kapele, li na le litšebeletso tse khutšoane, 'me li sa sebetse hantle, li hloleha ho fihlela litlhoko tsa sejoale-joale tsa ho cheka oli le khase.

Matla ke bophelo ba indasteri. Lisebelisoa tsa oli le khase tse tebileng tsa lefats'e li fetohile ntlha ea bohlokoa ntlafatsong ea oli le khase ea China, e leng se etsang hore ho be bohlokoa ho hlola mathata a mahlale a ho cheka.

II.  Li-Alloys tse thata: Sesebelisoa sa Bohlokoa sa ho Tobana le Libopeho tse Thata

Li-hard alloys li fetohile lisebelisoa tse loketseng ho chekoa ha oli le khase ka lebaka la ho thatafala ha tsona, matla a tsona a phahameng, le ho se sebetse ka tsela e ikhethang.

Li hlahisoa ka sintering tungsten, cobalt le phofo e meng ea tšepe ka mocheso o phahameng, ho fihlela boima bo fetang 90 sekaleng sa Mohs—ho feta hōle thepa ea tšepe e tloaelehileng.

III.  Katleho ea Theknoloji le Mekhoa e Mecha ea Sebopeho

Ho sebetsana le libopeho tse tebileng le tse rarahaneng, theknoloji ea "hard alloy drill bit" e ntse e tsoela pele ho ntlafatsa.

Li-cutters tsa Polycrystalline diamond compact (PDC) tse sebelisoang ho cheka oli le khase li na le 'mele o thata oa motsoako oa alloy le lera la daemane le kopantsoeng le lona.

'Mele o entsoeng ka motsoako o thata o sebelisa sebopeho se nang le mekhahlelo e 'meli—moko o ka hare o entsoeng ka moqomo o thata oa alloy o thata haholo le lesela le kantle le entsoeng ka lesela le thata le thata, le sa senyeheng, le nang le tšupu e tšesaane ea tšepe e hanyetsanang le mocheso o phahameng e kentsoeng lipakeng tsa tsona.

Moqapi ona o tiisa hore motheo oa motsoako o thata oa alloy o na le boima bo phahameng le matla, ha bokaholimo bo ka ntle bo fana ka boima bo phahameng le khanyetso e ikhethang ea khoholeho ea mobu, e leng se etsang hore e tšoanelehe bakeng sa maemo a phahameng a ho cheka le ho phunya.

IV.  Katleho ea Kopo e Bontša Bohlokoa

Lithako tsa ho cheka tse thata li bapala karolo ea bohlokoa ts'ebetsong ea ho cheka oli. Ba khona ho sebetsana le likarolo tse fapaneng tsa majoe a thata, joalo ka granite le quartzite.

Likonopo tse thata tsa alloy li bonts'a boima bo phahameng haholo le kganyetso e hlahelletseng ya ho apara, e li nolofalletsang ho mamella likhohlano tse matla le ho khathala ha nako e telele ea ho cheka.

Lisebelisoa tsa alloy tse thata li boetse li fana ka khanyetso e ntle ea tšusumetso, e ba lumellang ho mamella litlamorao tse fapaneng tsa tšohanyetso nakong ea ts'ebetso ea ho cheka, ho netefatsa botsitso le ts'ebetso ea ts'ebetso ea ho cheka.

V.  Litebello tsa Kamoso le Mathata a Tlang

China's "14th Five-Year Plan" explicitly emphasizes enhancing oil and gas supply capacity and improving development standards, charting the course for the advancement of hard alloys in the oil and gas drilling sector.

Ha botebo ba ho cheka oli le khase bo ntse bo eketseha le bokhoni ba ho cheka bo ntlafala, litlhoko tsa ts'ebetso bakeng sa likotoana tsa ho cheka alloy le tsona li tla phahama.

Likhoebo tsa indasteri li se li shebane le lipatlisiso, nts'etsopele le tlhahiso ea likonopo tsa boleng bo holimo le li-PDC tsa maemo a holimo bakeng sa ho ntšoa ha oli le khase. Ba ntse ba kenella thutong ea li-alloys tsa ho cheka seliba se tebileng, ba ntse ba leka ho rarolla mathata a "bottleneck" ho cheka matla a naha le lisebelisoa tsa ho cheka majoe.
