Thaum xov yob tuaj yeem txhim kho lub laum yeeb cov yeeb nkab lub zog thiab tawv tawv thaum tsim khoom, nws tsis yog ib qho txheej txheem yuam kev.
I. LUJ YEEB RAU COV TXHEEJ TXHEEM
Raws li ib qho cuab yeej tseem ceeb hauv roj drilling {{0} Txuas lub laum me ntsis rau lub rig {} Cov kav dej txuas ntxiv rau cov theem hauv qab no:
Cov khoom siv xaiv: High {- Lub zog alloyoy ib txwm siv los ua kom muaj kev tiv thaiv huab thiab cuam tshuam hauv kev ua haujlwm hnyav drilling.
Ntaub: Raw hlau yog puab cov txiav, sib tsoo, thiab drilling ntawm tshuab cov cuab yeej ua qauv.
Kev Kho Cua Sov: Quenching thiab tempering cov txheej txheem txhim kho lub zog / hardness thaum txo cov kev ntxhov siab sab hauv.
Lub xov: Precision tig, sib tsoo, thiab ncab kom ua kom paub tseeb qhov tseeb ntawm qhov tseeb thiab qhov zoo.
Ii. Lub Hom Phiaj Xov Xwm Dov
Xov yob ua cov khoom sib tsoo hisoves ntawm cov yeeb nkab sab npoo av, txhim kho:
Torsionional KujThiabKev zam txim tsis taus
Nto hardness thiab tensile lub zog, lub neej ua haujlwm ntev
Txawm li cas los xij, tsis yog txhua qhov tho kav kav yuav tsum tau xov dov. Non-threaded pipes suffice for light-duty operations, whereas heavy-duty/long-duration drilling necessitates threaded pipes.
III. Cov Qauv Xaiv
Laum Kev Xaiv Raws Nyob ntawm Kev Siv Ua Haujlwm thiab ib puag ncig:
Khoom: Tsawg {{- lub zog alloys rau cov dej ntiav; Siab - muaj zog alloys rau cov qhov dej tob tob.
Qho loj: Ntev, txoj kab uas hla, thiab phab ntsa tuab yuav tsum ua kom haum nrog phiaj xwm.
Kev Ntsuas Cov Khoom Zoo: Hwm cov kav dej pom kev ua kom muaj zog, hardness, thiab tawv, nrog qhov tsis xws luag - dawb qhov chaw.
IV. Tag
Raws li qhov tsis tseem ceeb drilling Cheebtsam, tho kav 'kev tsim khoom lag luam zoo ncaj qha cuam tshuam ncaj qha cuam tshuam thiab kev nyab xeeb. Ho xov yob txhim kho kev ua tau zoo, nws nyob ntawm yeem. Kev xaiv kev xaiv kev xaiv qhov xav tau nrog cov txheej txheem ua kom zoo.
