Qhov zoo ntawm PDC cov khoom

Polycrystalline pob zeb diamond compact (PDC) thiab PDC laum khoom tau qhia rau lub khw rau ntau xyoo lawm. Lub sijhawm ntev no,PDC cutter thiab PDC laum me ntsis tau ntsib ntau qhov kev poob qis hauv lawv cov theem pib, kuj tau ntsib kev txhim kho zoo. Maj mam tab sis thaum kawg, PDC cov khoom maj mam hloov cov khoom siv nrog kev txhim kho txuas ntxiv hauv PDC cutter, me ntsis stability, thiab me ntsis hydraulic qauv. PDC cov khoom tam sim no nyob ntau dua 90% ntawm tag nrho cov duab drilling hauv ntiaj teb.

Lub pob zeb diamond laum me ntsis yog siv nyob rau hauv yuav luag txhua daim ntawv thov xws li geothermal zog drilling, mining, dej zoo, natural gas drilling, thiab roj zoo drilling.

Nov yog qee qhov zoo ntawm PDC cov khoom.

1. Nqi-zoo

PDC cov khoom tuaj yeem ua tau zoo heev. Tsis zoo litricone ntsis, tsis muaj qhov txav ntawm PDC me ntsis los hnav. Cov pob zeb hluavtaws hluavtaws tuaj yeem nti, tab sis tus PDC cutter tuaj yeem muab rho tawm thiab ib qho tshiab tuaj yeem muab tso rau hauv nws qhov chaw. Rebuilding PDC me ntsis yog ib txwm nyob ib nrab ntawm tus nqi ntawm kev yuav khoom tshiab.

2. Tus nqi nkag

PDC cov khoom, hauv kev tsim kom raug, muaj qhov tsis txaus ntseeg ntawm kev nkag mus. Cov qauv uas PDC cov khoom ua tau zoo suav nrog tab sis tsis txwv rau shale, limestone, sandstone, thiab av nplaum. PDC cov khoom tuaj yeem nyob qhov twg mus rau 3-5 zaug sai dua li cov khoom tri-cone.

3. Kev txuag nqi

PDC cov khoom txuag nyiaj. Vim tias PDC cov khoom siv tho qhov nrawm dua, muaj sijhawm txuag ntau. Lub sijhawm txuag tso cai rau lub tshuab driller ua tiav cov haujlwm ntau dua hauv lub sijhawm luv. Ntawm ib txoj hauj lwm me me, nws yog teev thiab hnub cawm. Ntawm txoj hauj lwm loj, nws yog lub lis piam thiab hli tau txais kev cawmdim. Cov txiaj ntsig ntawm kev ua tiav txoj haujlwm sai dua yuav suav nrog kev txuag ntawm tus txiv neej-teev thiab roj, kev sib ntsib thiab / lossis tshaj li lub sijhawm, thiab siv cov khoom siv tsawg dua thiab cov khoom siv.

Zuag qhia tag nrho, muaj ntau yam txiaj ntsig rau drilling nrog PDC cov khoom. Ib yam li txhua yam, kev lag luam drilling yog ib txwm hloov. Kev hloov hauv tshuab thiab drilling tuaj yeem yog qhov zoo heev. PDC cov khoom tuaj yeem yog qhov kev hloov pauv uas ua rau qhov txawv rau koj.
