Kev faib tawm thiab kev xaiv
Sep 10, 2024| Tam sim no muaj ntau hom kev xyaum siv hauv kev lag luam roj av. Laum khoom raug cais raws li kev sib txawv ntawm kev sib txawv. Lawv tuaj yeem muab faib ua pob zeb diamond laum khoom, lub khob hliav qab cov khoom siv thiab cov khoom siv laum. Peb lub laum me me no yog cov ntaub ntawv laum me me tshaj plaws. Ntawm peb hom kev xyaum xyaum, feem ntau siv thiab siv dav hauv cov roj drilling yog cov menyuam lub khob hliav qab, uas kuj tau siv dav. Muab piv rau peb lub laum khoom no, qhov tsawg kawg yog siv yog scraper laum me ntsis. Kab lus no feem ntau qhia txog pob zeb diamond laum cov khoom thiab cov menyuam lub khob hliav cov khoom siv.
Pob zeb diamond
Cov cuab yeej drilling uas nws txiav ntug siv cov khoom siv pob zeb diamond yog pob zeb diamond laum me ntsis. Lub ntsiab kom zoo dua ntawm pob zeb diamond laum me ntsis yog tias nws tuaj yeem hloov kho rau kev tsim nrog ntau dua abrasiveness thiab nyuaj geology, thiab nws cov kev ua tau zoo kuj tseem zoo. Nws muaj qhov zoo heev hauv kev kub ceev drilling.
Raws li qhov sib txawv ntawm cov strata uas lawv tau yoog, pob zeb diamond laum khoom tuaj yeem muab faib ua ob pawg: pob zeb diamond zoo tib yam laum khoom thiab polycrystalline pob zeb diamond composite ntawv laum khoom. Ntawm ob pawg no, pob zeb diamond zoo tib yam laum cov khoom tsim nyog rau kev tsim nrog ntau dua abrasiveness, nyuaj geology, thiab complex geology; polycrystalline pob zeb diamond composite laum khoom tuaj yeem siv dav hauv cov txheej txheem nyuaj, cov qauv muag muag, thiab cov qauv mos mos thiab tawv. Kev tsim muaj ntau yam kev siv. Qhov sib txawv ntawm cov hniav yog qhov txawv ntawm ob lub pob zeb diamond xyaum.
Polycrystalline pob zeb diamond composite disc laum khoom feem ntau muaj plaub yam, xws li pob zeb diamond composite discs, nozzles, matrix thiab laum lub cev; zoo tib yam pob zeb diamond laum khoom feem ntau muaj plaub yam, xws li pob zeb diamond hais, nozzles, matrix thiab laum lub cev. Vim hais tias qhov kev ua tau zoo ntawm pob zeb diamond laum khoom yog qhov zoo, thaum xaiv pob zeb diamond laum khoom ua cov cuab yeej siv roj, lawv tuaj yeem laum ntawm kev kub ceev thiab nthuav dav qhov tob tob rau qee qhov. Nyob rau hauv tus txheej txheem ntawm kev siv pob zeb diamond laum khoom rau cov roj drilling kev ua haujlwm, cov hauv qab no yuav tsum tau ua tib zoo saib:
Ua ntej, tus nqi ntawm pob zeb diamond laum khoom yog qhov siab, yog li koj yuav tsum tau ceev faj thaum siv lawv kom txo qis qhov kev puas tsuaj;
Thib ob, pob zeb diamond laum cov khoom muaj qee yam tsis xws luag hauv thermal stability, yog li qhov kev ua haujlwm txias thiab ntxuav ntawm lub laum me ntsis yuav tsum tau ua kom ntseeg tau thaum siv nws;
Thib peb, nws qhov kev ntxhib los mos yog nkig, yog li qhov cuam tshuam tsis zoo ntawm pob zeb diamond laum cov khoom yuav tsis zoo, thiab kev ua haujlwm nruj thiab cov qauv yuav tsum tau ua raws li cov kev cai cuam tshuam ntawm pob zeb diamond laum khoom.
Iav log
Raws li cov qauv ntawm cov menyuam lub khob hliav qab me ntsis, nws tuaj yeem muab faib ua tsib ntu: qhov muag dej, kabmob, xibtes, lub khob hliav qab thiab lub cev me ntsis. Yog hais tias nws yog lub dav hlau kaw hom rau cov menyuam laum me ntsis, nws feem ntau kuj suav nrog cov roj cia them nyiaj. Cov xov feem ntau yog nyob rau sab sauv ntawm cov menyuam lub khob hliav qab me ntsis, thiab cov hlua laum thiab cov xov txuas rau ib leeg. Muaj ib lub khob hliav qab ntawm lub laum me ntsis, nrog peb xib teg ntawm nws. Lub khob hliav qab yog ntsia rau ntawm lub khob hliav qab, thiab muaj cov kabmob ntawm lub khob hliav qab thiab txhua lub khob hliav qab. , lub khob hliav qab yuav tawg lub pob zeb los ntawm nws tus kheej txiav hniav. Lub channel ntawm drilling kua yog lub qhov dej ntawm lub laum ntsis. Nyob rau hauv cov txheej txheem ntawm cov roj drilling, los ntawm transverse shear nyhuv thiab longitudinal vibration nyhuv thaum lub sij hawm drilling txheej txheem, cov menyuam lub khob hliav qab me ntsis yuav ua tiav lub hom phiaj ntawm kev tawg lub pob zeb, yog li ua kom lub drilling ceev.
Thaum xaiv cov menyuam lub khob hliav qab me ntsis raws li cov cuab yeej siv roj drilling, kev xaiv ntawm cov menyuam lub khob hliav qab yuav tsum tau ua raws li qhov tseeb ntawm cov khoom siv drilling, qhov tseeb ntawm kev tsim, thiab cov ntaub ntawv geological thiab tsim cov ntaub ntawv ntawm cov khoom siv drilling. cov roj av uas nyob ib sab. Thaum txiav txim siab, cov teeb meem tseem ceeb uas yuav tsum tau xav txog yog cov hauv qab no:
Ua ntej, nws yuav tsum tau txiav txim siab seb puas muaj kev sib tshuam ntawm cov mos mos thiab tawv tawv hauv qhov tsim drilling;
Qhov thib ob, nws yuav tsum tau txiav txim siab seb qhov kev sib txawv ntawm qhov sib txawv ntawm qhov drilling thiab kev ua haujlwm nkhaus yog qhov xav tau hauv kev ua haujlwm roj drilling;
Thib peb, qhov tseeb qhov tob ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov roj av yuav tsum tau txiav txim siab;
Thaum kawg, qhov drilling geology, grindability thiab hardness ntawm lub tsim yuav tsum tau xav txog.
