PDC, lossis polycrystalline pob zeb diamond sib nraus, hlais tau ua kev ua si-hloov pauv hauv kev lag luam drilling. Cov cuab yeej txiav no tau hloov cov tshuab khiav hloov hluav taws xob los ntawm kev ua kom muaj txiaj ntsig thiab txo tus nqi. Tab sis qhov twg pdc cutters los ntawm, thiab lawv tau ua li cas nrov?
Keeb kwm ntawm pdc cutters hnub rov qab mus rau xyoo 1950 ntawm hluavtaws pob zeb diamond tau tsim thawj zaug. Cov pob zeb diamond tau tsim los ntawm kev ua kom haum rau cov kev ntsuas siab thiab kub, tsim cov khoom uas nyuaj dua li lub ntsej muag ntuj. Hluavtaws hluavtaws nrawm nrawm nrawm nrawm nrawm nrawm hauv kev siv cov ntawv thov, suav nrog kev xyaum.
Txawm li cas los xij, siv cov hluavtaws hluavtaws hluavtaws hauv kev drilling tau nyuaj. Lub pob zeb diamond feem ntau yuav tawg lossis tshem tawm ntawm cov cuab yeej, txo nws cov txiaj ntsig thiab xav tau hloov ntau zaus. Txhawm rau hais txog cov teeb meem no, cov kws tshawb nrhiav tau pib sim nrog kev sib txuas hluavtaws pob zeb diamond nrog lwm cov ntaub ntawv, xws li tungsten carbide, los tsim cov cuab yeej ruaj khov thiab muaj txiaj ntsig ntau.
Xyoo 1970, thawj zaug pdc cutters tau tsim, muaj ntawm lub pob zeb diamond txheej sib khi ua rau tungsten carbide substrate. Cov txiav no tau pib siv hauv kev lag luam mining, tab sis lawv cov txiaj ntsig sai tau pom meej nyob rau hauv cov roj thiab roj drilling cov ntawv thov. PDC cutters muab sai dua ntais thiab ntau dua drilling, txo cov nqi thiab nce ntxiv cov khoom lag luam.
Raws li thev naus laus zis txhim kho, PDC cutters tau dhau los tau ntau dua, nrog cov qauv tshiab tsim thiab cov ntaub ntawv ntxiv thiab versatility. Niaj hnub no, pdc cutters yog siv nyob rau hauv ntau ntawm cov ntawv thov drilling, suav nrog cov chaw ua si geothermal, mining, kev tsim kho, thiab ntxiv.
Kev siv cov ntaub pua plag pdc kuj tau ua rau nce qib hauv cov kev sib dhos, xws li kab rov tav drilling thiab ditring drilling. Cov tswv yim no tau ua tau los ntawm kev nce zuj zus thiab ruaj khov ntawm pdc cutters, tso cai rau ntau meej thiab tswj tau drilling.
Hauv kev xaus, PDC Cutters muaj keeb kwm kev sib txawv ua ke rov qab mus rau kev txhim kho ntawm cov hluavtaws hluavtaws hluav taws xob hauv xyoo 1950. Lawv cov kev hloov kho thiab kev loj hlob tau ua rau kev nce qib tseem ceeb hauv cov tshuab drilling, txhim kho cov nqi, thiab nthuav dav cov kev siv. Raws li xav tau rau qhov nrawm dua thiab ua kom muaj kev loj hlob ntxiv mus, nws pom tseeb tias PDC cutters yuav nyob twj ywm tseem ceeb ntawm kev lag luam drilling.
