PDC Cutter rau PDC Core ntsis
PDC Cutter rau PDC Core ntsis
PDC core ntsis yog tsim nrog PDC cutters thiab matrix lub cev los yog steel lub cev. PDC core ntsis yog zoo tagnrho rau daim ntawv thov nrog high-powered laum rigs kev khiav hauj lwm ntawm kuj tsis tshua muaj kev sib hloov ceev. Tab sis lub neej thiab kev nkag mus tuaj yeem ua tau zoo dua piv nrog cov khoom ntog.
PDC core ntsis muaj ntau sintered polycrystalline-pob zeb diamond studs ntawm lub cev matrix. PDC cutter muaj ultra-fine hluavtaws pob zeb diamond hais sintered ua ke los ntawm kev kub siab thiab kub. Nyob rau hauv qab ntawm no pob zeb diamond txheej yog ib tug tungsten carbide stud uas yog brazed ncaj qha mus rau hauv me ntsis lub cev. Ob hom tseem ceeb ntawm PDC cutters yog muaj rau PDC core me ntsis: pav ca tsim los yog dome. PDC cutters tau teem rau ntawm lub yas thiab tuaj yeem ua kom haum rau qhov loj heev compressive thiab shear loads generated thaum lub sij hawm drilling. Muaj txog kaum PDC cutters ntawm lub cev matrix, nyob ntawm qhov loj me me ntawm cov tub ntxhais. Qhov loj me ntsis yog, ntau dua cov PDC cutters ntawm nws.
PDC core me ntsis muaj qhov dej ntws los yog qhov chaw qhib thiab kho tau ntawm lub taub hau ruaj khov. Nozzles xav tau vim lawv muab cov dav hlau turbulent ntws los ntawm cov khoom kom cov chaw txiav huv si.
Feem ntau homogeneous sedimentary pob zeb tsim xws li shale, dolomite, limestone, thiab sandstone tau yooj yim ua haujlwm nrog PDC core me ntsis. Rau cov tawv tawv abrasive xws li dolomite thiab limestone, matrix lub cev PDC core ntsis feem ntau yog siv vim lawv muab kev tiv thaiv zoo heev rau hnav. Steel lub cev PDC core ntsis feem ntau yog siv thaum ua hauj lwm ntawm softer formations xws li sandstone. Cov tub ntxhais me ntsis siv lub shaving los yog shearing txiav txim thaum ntsib qhov tsim. Qhov kev sib hloov ceev ntawm cov tub ntxhais me ntsis yog qhov siab dua li lwm cov khoom siv rotary. Hydraulic ntawm PDC tub ntxhais me ntsis muaj qhov tsim los ua kom lub qhov huv si thiab cov tub ntxhais txias txias, yog li ua kom lub neej ntev.
Yog tias koj txaus siab rau PDC cutters thiab xav tau cov ntaub ntawv thiab cov ntsiab lus ntxiv, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa US MAIL rau hauv qab ntawm nplooj ntawv.
