Vim li cas thiaj tsis tuaj yeem Roj thiab Roj Extraction Ua tsis muaj Alloys nyuaj?

Thaum tshawb nrhiav cov roj thiab cov khoom siv roj sib sib zog nqus hauv lub ntiaj teb, cov cuab yeej siv tawv tawv tau dhau los ua tib neeg lub cuab yeej ntse hauv kev tawm tsam cov pob zeb nyuaj, ua haujlwm lav rau Tuam Tshoj txoj kev sib sib zog nqus hauv ntiaj teb.

Nyob rau hauv tej thaj chaw deb Tarim Phiab, lub qhov dej Yuejin 3-3XC ntawm "Deep Earth No. 1" twb dhau ib tug drilling qhov tob ntawm 10,000 meters. Thaj chaw no, nrog rau nws cov xwm txheej geological nyuaj heev, muab cov kev xav tau nruj ntawm cov khoom siv laum. Dab tsi kov yeej cov kev nyuaj no yog cov "hlau hniav thiab lub puab tsaig steel" ua los ntawm cov hlau alloys nyuaj.

I. Kev Sib Tw Hauv Ntiaj Teb Sib sib zog nqus, Drilling nyuaj

Raws li Tuam Tshoj txoj kev tshawb nrhiav roj thiab roj tau nce mus rau hauv cov txheej txheem sib sib zog nqus thiab tob tob, cov roj av tau ntsib qhov xwm txheej huab cua uas yog "peb ultras thiab ib qhov siab" - ultra-dav, ultra-siab kub, ultra-siab siab, thiab siab sulfur ntsiab lus.

Nyob rau hauv cov xwm txheej zoo li no, cov cuab yeej xyaum zoo tib yam tawm tsam ua. Cov khoom siv tsoos laum hnav tawm sai sai, muaj kev pabcuam luv luv, thiab kev ua haujlwm qis, ua tsis tau raws li qhov xav tau ntawm cov roj niaj hnub thiab roj drilling.

Lub zog yog lub neej ntawm kev lag luam. Kev sib sib zog nqus roj thiab roj av tau dhau los ua qhov tseem ceeb hauv pem hauv ntej ntawm Tuam Tshoj txoj kev txhim kho roj thiab roj, ua rau nws yog qhov tseem ceeb los kov yeej cov kev sib tw thev naus laus zis.

II.  Hard Alloys: Cov cuab yeej tseem ceeb rau Tackling Hard Formations

Cov alloys tawv tau dhau los ua cov khoom siv zoo tshaj plaws rau cov roj thiab cov roj drilling vim lawv cov hardness siab, siab zog, thiab tshwj xeeb hnav tsis kam.

Lawv yog tsim los ntawm sintering tungsten, cobalt, thiab lwm yam hlau hmoov nyob rau hauv high kub, ua tau ib tug hardness ntawm ntau tshaj 90 nyob rau hauv lub Mohs nplai - deb tshaj ntawm cov tsoos steel cov ntaub ntawv.

III.  Technological Breakthroughs thiab cov qauv tsim tshiab

Txhawm rau hais txog kev sib sib zog nqus thiab ntau txoj kev tsim, nyuaj alloy laum me ntsis thev naus laus zis txuas ntxiv tsim kho tshiab.

Polycrystalline pob zeb diamond compact (PDC) cutters siv nyob rau hauv cov roj thiab roj drilling muaj ib tug nyuaj alloy composite lub cev thiab ib pob zeb diamond txheej integrated nrog nws.

Lub cev sib xyaw ua ke siv cov txheej txheem dual-txheej txheej-cov tub ntxhais sab hauv uas ua los ntawm cov tawv tawv tawv tawv tawv thiab txheej txheej ua los ntawm cov tawv tawv tawv, siab hnav-resistant hard alloy tube, nrog lub siab kub-resistant hlau nyias raj ntawm lawv.

Qhov kev tsim no ua kom ntseeg tau tias cov tub ntxhais ntawm cov tawv tawv alloy substrate muaj qhov toughness siab thiab lub zog, thaum lub npoo sab nrauv muaj qhov tawv tawv thiab qhov tshwj xeeb yaig tsis kam, ua rau nws tsim nyog rau kev cuam tshuam thiab siab yaig drilling.

IV.  Kev ua tau zoo ntawm daim ntawv thov qhia tus nqi

Hard alloy laum khoom ua si lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm cov roj drilling. Lawv tuaj yeem yooj yim tackle ntau cov pob zeb nyuaj, xws li granite thiab quartzite.

Hard alloy khawm khoom nthuav tawm heev hardness thiab zoo heev hnav tsis kam, ua rau lawv tiv taus qhov kev sib txhuam loj heev thiab hnav thaum lub sijhawm ua haujlwm ntev ntev.

Cov ntaub ntawv tawv tawv kuj muaj kev cuam tshuam zoo heev, ua rau lawv tiv taus ntau yam kev cuam tshuam tam sim ntawd thaum lub sijhawm drilling, ua kom ruaj khov thiab txuas ntxiv hauv kev ua haujlwm drilling.

V. Lub zeem muag yav tom ntej thiab cov kev sib tw ua ntej

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.

Raws li cov roj thiab cov roj drilling qhov tob txuas ntxiv mus ntxiv thiab kev ua kom zoo dua qub, cov kev ua tau zoo ntawm cov khoom siv tawv alloy laum yuav nce ntxiv.

Kev lag luam kev lag luam tam sim no tsom mus rau kev tshawb fawb, kev tsim kho, thiab kev tsim cov pob khawm zoo thiab high-end PDC substrates rau roj thiab roj extraction. Lawv tab tom delving rau hauv txoj kev tshawb fawb ntawm qhov sib sib zog nqus-zoo drilling alloys, siv zog los daws cov teeb meem "bottleneck" nyob rau hauv lub teb chaws lub zog drilling thiab pob zeb excavation cov ntaub ntawv.
