PDC Cutter Rau Roj Thiab Roj Drilling

Nyob rau hauv tus txheej txheem ntawm tib neeg txoj kev loj hlob, tsheej lab ntawm cov cuab yeej tau siv los ua qhov, tab sis muaj ib tug me ntsis txiav txim lawv tag nrho. Nyob rau hauv feeb drilling, hom roj thiab roj laum tshaj plaws niaj hnub no yog PDC laum me ntsis. Nws tau paub ntev ntev tias shearing yog qhov ua tau zoo tshaj plaws los ua tsis tau ntau hom tock. Tab sis rau feem ntau ntawm lub sijhawm ntawd, cov khoom txiav cov khoom muaj los txiav cov pob zeb yog me me los yog yuav hnav sai heev rau kev xyaum kev lag luam, thiab tom qab ntawd tuaj PDC.

Lub focal point ntawm PDC me ntsis yog polycrystal thiab pob zeb diamond cutters, uas yog qhov twg nws tau txais nws lub npe. Cov cutters feem ntau yog cylinders nrog ib tug txiv neej ua dub pob zeb diamond txiav lub ntsej muag, engineered los tiv thaiv qhov kev puas tsuaj loj heev thiab kub uas los ntawm drilling los ntawm pob zeb. Pob zeb diamond txheej thiab substrate yog sintered nyob rau hauv ultra-siab siab thiab ultra-siab kub. Lub pob zeb diamond yog loj hlob ntawm carbide substrate, tsis coated. Lawv ua ke ruaj khov. PDC cutters yog siv nyob rau hauv yuav luag txhua daim ntawv thov xws li geothermal zog drilling, mining, dej zoo, natural gas drilling, thiab roj zoo drilling.

PDC cutters tau teem rau hauv 3d geometry hu ua cov qauv txiav. Cov qauv txiav tej zaum yuav zoo li yooj yim, tab sis feem ntau nws yog qhov nyuaj tshaj plaws ntawm kev tsim me ntsis thiab feem ntau tsav qhov kev ua tau zoo ntawm me ntsis. Rau PDC me ntsis kom ua haujlwm tau zoo, cov qauv txiav yuav tsum nyob twj ywm. Vim li no, cov cutters feem ntau yog ua raws li cov kab, tso cai rau cov qauv txiav los tuav ua ke los ntawm cov hniav loj.

PDC cov khoom siv lub cev yog tag nrho ua los ntawm cov hlau ntawm qhov sib txuas pinned, thiab hloov mus rau cov khoom siv tungsten carbide sib xyaw rau ntawm qhov chaw sab nrauv. Lub cev me ntsis yog matrix lossis hlau nyob ntawm seb lawv tsim thiab siv ntau npaum li cas tungsten carbide. PDC cov khoom tuaj yeem tsim nrog ze li qhov tsis muaj qhov kawg ntawm kev hloov pauv hloov pauv rau cov kev xav tau tshwj xeeb ntawm kev sib txawv thiab hloov cov ntawv thov drilling. Niaj hnub no, ntau dua 70% ntawm cov khoom siv tho siv hauv cov roj thiab cov roj drilling yog PDCs. Thaum me ntsis tsim yog qhov tseem ceeb, tsis muaj PDC me ntsis tuaj yeem ua haujlwm yam tsis muaj PDC cutters.

ZZbetter tau tsom rau PDC cutter rau ntau tshaj 15 xyoo. Cov duab ntawm zzbetter PDC Cutter suav nrog:

1. Pav ca PDC cutter
