Polycrystalline Pob Zeb Diamond Cutters (PDC) kev txhim kho

Nrog rau kev txhim kho ntawm qhov ruaj khov me ntsis, kev siv zog tuaj yeem tsom mus rau kev txhim kho PDC cutters hauv 1990s. Kev nkag siab ntawm lub luag haujlwm ntawm qhov kev ntxhov siab nyob hauv PDC qhov kev ua tau zoo thiab kev ntsuas thiab tswj nws li cas tau los rau hauv nws tus kheej thaum xyoo 1990s. Ib tug qauv khoom raug qhia hauv qab no.

Ntau qhov haujlwm no tau tsav los ntawm cov tuam txhab me me kev siv zog nrog PDC cov neeg muag khoom hauv kev lag luam sib tw heev. Nws siv sijhawm ntau xyoo los ntawm qhov pib tsis-planar interfaces (NPI) cutter hauv xyoo 1984 rau qhov xwm txheej uas ntau tus neeg siv thiab cov neeg muag khoom txaus siab txaus siab rau lub tswv yim ntawm "tus tsim" cutters, lossis kos npe cutters, thiab cuam tshuam nrog cov teebmeem uas nws nthuav tawm. mus rau lub khw.

Ntau qhov kev txhim kho ntawm lub rooj pob zeb diamond tau qhia los ntawm xyoo 1990 thiab txog rau niaj hnub no, uas tau tsa cov kav ntev, hnav tsis kam, sib xws, lossis txuas ntxiv cov ntawv thov ntau yam ntawm PDC cov khoom. PDC Cutters nrog pob zeb diamond ntxhuav tshaj 4 hli tuab tau qhia.

Cov no muaj cov kav ntev kom ntev lub neej ntawm cov khoom los ntawm kev sib txuam sib xyaw. Lub nplhaib peripheral ntawm pob zeb diamond nyob rau sab nraud ntawm qhov tsis yog-planer interface tau dhau los ua qhov nrov thiab ze-tus qauv ntawm ntau cov cutters siv tsis ntev los no.

Cov kws tsim txuj ci tshwj xeeb tshwj xeeb "kos npe" cutters yog tam sim no tus qauv rau ntau lub tuam txhab me me. Muaj peev xwm txiav qhov kev ua tau zoo ntawm cov cutters los ntawm kev tswj cov kev ntxhov siab seem, lub peev xwm thauj khoom ntawm lub tshuab txiav, lub rooj thickness, hnav tsis kam, thiab lwm yam tso cai rau cov ntawv thov tshwj xeeb cutters siv rau hauv qhov tshwj xeeb ntawm qhov me me los txhim kho qhov kev ua tau zoo. . Daim ntawv thov tshwj xeeb cutters yog tam sim no feem ntau siv thoob plaws hauv kev ua kom zoo dua me ntsis rau ib hom kev drilling, tsim, lossis daim ntawv thov.

Kev txhim kho hauv chamfer thev naus laus zis thiab kev siv ntau lub chamfers, patented los ntawm Hughes hauv 1995 tau dhau los ua thoob plaws hauv nruab nrab-1990s. Thaum siv tau zoo, qhov tawg tsis kam ntawm lub tshuab txiav thaum lub sij hawm drilling tau nce 100% nrog rau qhov sib txuas tseem ceeb hauv kev ua haujlwm ntev thiab ntev ntawm kev khiav.

Lwm qhov kev tsim kho tshiab yog qhov kev taw qhia ntawm patented polished cutter rau laum khoom los ntawm Hughes hauv xyoo 1995. Kev tshawb fawb hauv chav kuaj tau pom tias muaj kev txo qis hauv kev sib txhuam ntawm cov cutter hauv qee qhov kev tsim, thiab qhov no tau ua pov thawj hauv tag nrho cov kev ntsuas drilling thiab kev sim teb. Me ntsis kev ua tau zoo tau ntsuas tau zoo dua qub, thiab cov yam ntxwv no tseem siv dav dav.

Cov neeg nkag tshiab hauv kev ua lag luam ntawm cov khoom zoo PDC txiav cov hniav, nrog rau cov tuam txhab laum loj, txuas ntxiv ua cov kev hloov kho thiab kev tsim kho tshiab ntawm cov ntaub ntawv tshiab thiab cov txheej txheem tsim khoom kom cov kev ua tau zoo ntawm PDC txiav cov hniav thiab PDC laum cov khoom tuaj yeem txhim kho tsis tu ncua.

Rau siab tshaj plaws kev pab cuam lub neej thiab nthuav cov drilling efficiency nyob rau hauv qhov tob tob thiab tag nrho cov pob zeb formations, lub ZZbetter PDC cutter yog zoo tagnrho xaiv. Cov cuab yeej no ua haujlwm zoo thoob plaws txhua hom kev siv thiab yooj yim rau braze. Nws kuj muaj thermal stability siab thiab zoo heev rau kev xyaum me ntsis refurbishing.

Yog tias koj txaus siab rau PDC cutters thiab xav paub ntau ntxiv thiab cov ntsiab lus, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa US MAIL hauv qab ntawm nplooj ntawv.
