Dab tsi yog qhov txawv ntawm steel lub cev thiab matrix lub cev PDC ntsis

PDC laum me ntsis yog tsim los ntawm PDC cutters thiab steel, conbining qhov zoo cuam tshuam toughness ntawm hlau thiab hnav-tiv taus ntawm polycrystalline pob zeb diamond compact ua rau PDC me ntsis muaj ceev footage nyob rau hauv cov txheej txheem drilling.Lub cev hlau PDC me ntsis tau nrawm dua hauv kev tsim cov mos mos thaum lub cev matrix PDC me ntsis yog ntau dua los tiv thaiv hnav resistant, matrix lub cev me ntsis tuaj yeem xyaum tsim nyuaj thaum piv nrog steel lub cev PDC me ntsis vim nws lub cev tungsten carbide matrix, tab sis nws muaj qeeb footage thaum piv nrog steel lub cev PDC laum me ntsis.Yog tias koj txaus siab rau ib qho ntawm PDC cov khoom, pls hu rau Far Eastern Drilling

Matrix Lub Cev PDC Cov Khoom vs Steel Lub Cev PDC Cov Khoom

Yog tias koj tau ua haujlwm hauv qhov drilling rau txhua lub sijhawm, koj tau hnov ​​​​txog PDC cov khoom.PDC sawv cev rau "polycrystalline pob zeb diamond compact," uas piav qhia txog cov khoom siv sib xyaw ua ke uas ua rau cov khoom no 'txiav nto.Ob leeg Matrix Lub Cev PDC thiab Hlau Lub Cev PDC yog tsim nrog cov khoom sib xyaw no.

Cov khoom no mus los ntawm ntau lub npe.Lawv feem ntau hu ua:

• PDC Cov
• Polycrystalline pob zeb diamond compact khoom
• Composite chip hniav khoom
• Polycrystalline pob zeb diamond txiav block khoom

PDC cov khoom siv feem ntau siv rau cov roj drilling - tab sis yog nrov hauv lwm cov lag luam thiab.Lawv tau tsim nyob rau xyoo 1976 thiab tam sim no nrov heevroller-cone khoom(ib yam me me uas muaj rotating qhov chaw).Thaum PDC cov khoom muaj keeb kwm ntev ntawm kev ua tiav, lawv txuas ntxiv txhim kho thiab txhim kho tas li los ntawm kev txiav cov ces kaum tshiab, kev npaj, thiab cov khoom siv.Cov khoom no muaj txiaj ntsig zoo thaum lawv ua haujlwm los tshem tawm cov pob zeb tsim ntau dua li crushing lawv.Txhua xyoo, kev nce qib tshiab hauv kev siv thev naus laus zis txhim kho kev ua tau zoo ntawm PDC cov khoom thiab txhim kho qhov nrawm nrawm.

Cov khoom no hu ua "lub qhov ntswg-rau-lub-grindstone" cov khoom ntawm kev lag luam drilling - lawv tau txais txoj haujlwm tiav thiab tuaj yeem ua haujlwm tau zoo rau ntau yam kev pabcuam thiab tsim hom - tsis muaj qhov txav mus los kom muaj kev cuam tshuam, tsis muaj fuss, tsuas yog zoo drilling rau txhua yam koj xav tau.

PDC Bits yog dab tsi?

Muaj ob yam tseem ceeb ntawmPDC laum khoom- matrix lub cev PDC khoom thiab steel lub cev PDC khoom.Ob qho tib si zoo ib yam li puag ncig cov khoom nrog plaub mus rau yim txiav cov qauv, lossis cov hniav, uas kiv cua tawm ntawm nruab nrab.Txhua cov hniav yog ces topped nrog ntawm kaum thiab peb caug cutters.Cov khoom muaj cov dej sib cais kom txias, thiab muaj lub nozzle ntawm lub apex ntawm me ntsis.Yog tias koj tab tom sim xav txog qhov me me no, nws zoo li me ntsis zoo li lub kaus mom huab tais hnav.

PDC cov khoom siv rau roj thiab roj drilling, geothermal drilling, dej zoo drilling, kev tsim kho drilling, mining thiab kab rov tav directional drilling.

Kev Tshawb Fawb Tom Qab PDC Cov Khoom

Tej zaum koj yuav tau kawm hauv tsev kawm ntawv tias pob zeb diamond yog cov khoom nyuaj tshaj plaws rau txiv neej.Nws yog!Thiab nws yog qhov zoo tshaj plaws rau kev txiav los ntawm lwm cov ntaub ntawv xws li pob zeb formations rau drilling.

PDC cov khoom siv me me, pheej yig, tib neeg tsim pob zeb diamond hauv lawv cov qauv txiav.Cov txheej txheem tsim cov pob zeb diamond ntawm cov khoom no nyuaj.Simplified, ntawm no yog cov txheej txheem rau tsim pob zeb diamond laum khoom:

• Cov pob zeb hluavtaws me me yog tsim
• Tom qab ntawd cov pob zeb diamond tau sib sau ua ke rau hauv cov pob zeb loj loj
• Tom qab ntawd cov crystals yog zoo li lub pob zeb diamond
• Cov rooj pob zeb diamond tom qab ntawd raug khi rau hlau, feem ntau yog tungsten carbide, thiab cov khoom siv hlau
• Qhov no dhau los ua ib feem ntawm qhov me me - muaj ntau cov cutters ntawm txhua tus hniav ntawm qhov me me
• Tom qab ntawd cov cutters yog txuas mus rau cov hniav, uas yog txuas rau lub cev ntawm me ntsis

Ua ke, cov cutters thiab cov hniav ntawm qhov kawg ntawm PDC me ntsis yog siv los txiav cov pob zeb tsim ntawm txhua yam.

Synthetic Diamonds nyob rau hauv Drill Bits

Raws li koj tuaj yeem pom, cov pob zeb hluavtaws hluavtaws yog cov khoom siv tseem ceeb rau PDC cov khoom.Hauv kev tsim cov khoom no, cov pob zeb me me ntawm pob zeb diamond (tseem hu ua pob zeb diamond grit) yog tsim.Cov grit no ruaj khov heev tab sis yuav tsis ruaj khov ntawm qib molecular thaum nws kub.Yog li, koj qhov PDC me ntsis yuav ua tsis tau yog tias tsis txias txaus thaum siv.

Txawm li cas los xij, cov pob zeb hluavtaws hluavtaws zoo kawg nkaus hnav-tiv taus;lawv yog cov khoom siv zoo tshaj plaws rau lub neej ntev thiab kav ntev.Hom hlau hloov yog tias koj xaiv lub matrix lossis steel lub cev me ntsis - tab sis lub pob zeb diamond tseem ceeb heev.PDC cov khoom tuaj yeem muaj lub neej ntev ntev raws li lawv tau txias txaus.
