Lub pob zeb diamond polycrystalline compact (PDC) laum me ntsis tau tsim los ntawm ib pab neeg tshawb fawb coj los ntawm Dr. Howard Hughes Sr. thaum xyoo 1970s. Dr. Hughes thiab nws pab neeg tau tsim PDC me ntsis raws li lwm txoj hauv kev rau cov menyuam lub khob hliav qab rau kev drilling los ntawm cov txheej txheem nyuaj. Lub invention ntawm PDC me ntsis revolutionized drilling tshuab los ntawm muab tus nqi siab dua ntawm kev nkag mus thiab txhim kho durability nyob rau hauv ntau yam kev siv drilling.
Txoj kev loj hlob ntawm PDC laum me ntsis tuaj yeem taug qab mus rau thaum ntxov 1970s thaum Dr. Howard Hughes Sr., tus kws tshaj lij Asmeskas thiab ua lag luam, tsim lub tuam txhab Hughes Tool. Dr. Hughes tau lees paub txog cov kev txwv ntawm cov tsoos roller cone khoom hauv kev drilling los ntawm cov txheej txheem nyuaj thiab abrasive ntsib hauv kev tshawb nrhiav roj thiab roj.
Hauv kev teb rau cov kev cov nyom no, Dr. Hughes tau sib sau ua ke ib pab neeg ua haujlwm thiab cov kws tshawb fawb los tshawb nrhiav cov ntaub ntawv tshiab thiab txiav cov thev naus laus zis rau cov cuab yeej drilling. Ib qho kev tawg tuaj nrog kev tshawb pom ntawm polycrystalline pob zeb diamond (PCD), cov khoom siv hluavtaws uas muaj cov pob zeb diamond sib txuas ua ke nyob rau hauv siab thiab kub.
Xyoo 1972, Hughes Tool Company tau ua daim ntawv patent rau polycrystalline pob zeb diamond compact (PDC) laum me ntsis, uas siv PCD cutters ua thawj txiav. Tsis zoo li cov menyuam lub khob hliav qab, uas tso siab rau cov hniav lossis cov khoom ntxig rau kev txiav, PDC cov khoom tshwj xeeb tsim cov qauv tsim nrog pob zeb diamond cutters sib txuas ncaj qha rau lub cev me ntsis.
Kev taw qhia ntawm PDC cov khoom sawv cev rau kev nce qib tseem ceeb hauv kev siv tshuab drilling. Lawv muab cov nqi nkag siab dua, txhim kho durability, thiab ncua lub neej me ntsis piv rau cov khoom siv rau cov menyuam cov khoom siv. PDC cov khoom tau txais txiaj ntsig sai sai hauv kev lag luam roj thiab roj rau lawv cov kev ua tau zoo thiab kev ua tau zoo hauv ntau daim ntawv thov drilling.
Tau ntau xyoo, kev nce qib hauv cov ntaub ntawv tshawb fawb thiab cov txheej txheem tsim khoom tau txhim kho kev tsim thiab kev ua tau zoo ntawm PDC laum khoom. Niaj hnub no, PDC cov khoom txuas ntxiv yog cov cuab yeej tseem ceeb hauv kev ua haujlwm drilling thoob ntiaj teb, tsav kev ua tau zoo thiab tsim khoom hauv kev tshawb nrhiav roj thiab roj thiab kev tsim khoom.
