PDC tsis-planar ntsej muag cutter

Thoob plaws hauv keeb kwm ntawm oilfield drilling, cov neeg ua haujlwm tau sim txhim kho kev xyaum ua kom zoo dua qub. Ntau qhov kev txiav txim siab, kev tsim, thiab cov khoom siv tau raug coj los ua kom nce tus nqi nkag (ROP), hnav-tiv taus, thiab tag nrho lub neej me ntsis. Cov tsoos polycrystalline pob zeb diamond cutter (PDC) thev naus laus zis tau ua kom tau txais txiaj ntsig zoo heev hauv kaum xyoo dhau los nrog cov duab sib xws thiab tus nqi nkag (ROP) kev txhim kho hauv kev ua haujlwm drilling. Qhov kev sib tw ntxiv yog tswj cov txheej txheem nyuaj nrog cov stringers muaj peev xwm thaum tswj xyuas kev ua haujlwm drilling thiab qhov siab tshaj plaws ROP peev xwm.

Qhov tsis tshua muaj pob zeb tawg ua haujlwm ntawm cov pa polycrystalline pob zeb diamond compact (PDC) cov khoom hauv cov txheej txheem nyuaj ua rau muaj kev txhim kho ntawm PDC txiav cov ntsiab lus los ntawm cov qauv mus rau cov qauv uas tsis yog-planar. Los ntawm kev hloov kho tus qauv planar PDC cutter lub ntsej muag geometry nrog cov tshiab ntiav ntiav recessed nta, ib qho kev txhim kho nyob rau hauv drilling efficiency tau pom nyob rau hauv cov ntaub ntawv no thiab ib tug nce nyob rau hauv cov footage. Los ntawm kev txheeb xyuas qhov cuam tshuam ntawm lub kaum sab xis ntawm lub nraub qaum, txiav qhov tob, lub kaum sab xis, thiab cov khoom siv pob zeb ntawm pob zeb tawg ua haujlwm, peb pom tias cov tshuab txiav tsis yog cov pob zeb feem ntau yog crushing thiab shearing thiab muaj kev ua haujlwm siab dua li cov pa PDC cutter. Thaum PDC me ntsis nrog convex ridge PDC cutters yog drilled rau hauv gravel txheej, lub gravel tsis cuam tshuam lub pob zeb diamond sib xyaw dav hlau ncaj qha tab sis ua rau linear sib cuag nrog lub convex ridge. Cov ridges ntawm PDC cutters ua ntej kev sib cuag nrog kev tsim thiab nyem cov pob zeb, ua rau muaj kev ntxhov siab nyob rau hauv cov gravel nto txheej, ua rau nws yooj yim dua rau qhov pib tawg thiab tawg. Daim ntawv thov daim teb qhia tau hais tias PDC tsis-planar cutter yog yooj yim rau nkag mus rau qhov tsim dua li cov pa cutter thiab ruaj khov dua nrog tsawg torque yuav tsum tau.

Ntawm ZZBETTER, peb tuaj yeem muab ob qho tib si planar cutter thiab non-planar PDC cutters, thaum tsis yog planar cutters nrog ntau yam kev cuam tshuam zoo, hnav tsis kam thiab ruaj khov. Raws li peb cov neeg siv khoom tau hais tias: PDC planar cutters yog qhov ci ntsa iab, siv tau yooj yim heev.

Yog tias koj txaus siab rau cov khoom lag luam tungsten carbide 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 mus rau US MAIL hauv qab ntawm nplooj ntawv.
