Daim ntawv thov
Pob zeb formations:
Oilfield roller cone laum khoom siv dav siv hauv ntau hom pob zeb tsim, suav nrog sandstone, shale, av nkos, thiab pob zeb nyuaj.Kev xaiv ntawm cov menyuam lub khob hliav me ntsis yog nyob ntawm qhov hardness thiab cov khoom ntawm cov pob zeb tsim.
Lub hom phiaj drilling:
Lub hom phiaj ntawm qhov drilling tseem cuam tshuam rau kev xaiv cov menyuam lub khob hliav qab cov khoom.Piv txwv li, qhov drilling roj qhov dej thiab cov nkev roj qhov dej yuav xav tau ntau hom kev xyaum ua kom haum raws li qhov sib txawv geological thiab cov kev xav tau ntawm qhov dej.
Drilling ceev:
Kev tsim thiab kev ua tau zoo ntawm cov menyuam lub khob hliav qab cov khoom siv ncaj qha cuam tshuam rau qhov nrawm nrawm.Thaum yuav tsum tau drilling ceev, nws yog ib qho tseem ceeb heev uas yuav tau xaiv cov laum khoom uas muaj kev txiav siab thiab hnav tsis kam.
Drilling ib puag ncig:
Oilfield drilling feem ntau tshwm sim nyob rau hauv ib puag ncig huab cua, nrog rau qhov kub thiab txias, kub siab, thiab hnav siab.Yog li ntawd, cov menyuam lub khob hliav qab yuav tsum muaj peev xwm ua haujlwm tsis tu ncua raws li cov xwm txheej no thiab muaj lub neej ua haujlwm ntev.
Hauv cov ntsiab lus, cov yam ntxwv thiab kev siv ntawm oilfield roller cone laum khoom nyob ntawm qhov xwm txheej geological, lub hom phiaj drilling, thiab ib puag ncig yuav tsum tau ua.Kev xaiv kom raug thiab kev saib xyuas ntawm cov menyuam lub khob hliav qab yog qhov tseem ceeb rau kev txhim kho drilling efficiency thiab txo cov nqi.Cov laum khoom no ua lub luag haujlwm tseem ceeb hauv cov roj av drilling thiab tseem ceeb heev rau kev lag luam hluav taws xob.
Yam ntxwv
Kev xaiv khoom siv:
Oilfield roller cone laum cov khoom feem ntau yog tsim los ntawm cov hlau tawv tawv (cov hlau tawv) vim tias lawv yuav tsum tau ua haujlwm nyob rau hauv high-temperature, high-pressure, thiab high-wear ib puag ncig.Hard alloys feem ntau muaj xws li cobalt thiab tungsten carbide Cheebtsam, uas muab zoo heev hardness thiab hnav tsis kam.
Taper thiab puab:
Cov duab thiab taper ntawm cov menyuam lub khob hliav qab tuaj yeem hloov kho kom haum rau qhov sib txawv geological thiab lub hom phiaj drilling.Cov duab uas muaj xws li tiaj tus (milled hniav), puag ncig (ntxig hniav), thiab conical (tri-cone) kom haum rau ntau hom pob zeb tsim.
Drill ntsis loj:
Qhov luaj li cas ntawm cov khoom laum tuaj yeem xaiv raws li txoj kab uas hla thiab qhov tob ntawm lub qhov dej kom ua tiav qhov kev ua haujlwm zoo drilling.Cov laum loj dua feem ntau yog siv rau qhov loj-inch qhov dej, thaum cov me me yog tsim rau me me-inch wellbores.
Txiav cov qauv:
Roller cone laum cov khoom feem ntau muaj cov qauv txiav xws li protrusions, txiav npoo, lossis cov lus qhia chisel txiav thiab tshem tawm cov pob zeb.Kev tsim thiab kev teeb tsa ntawm cov qauv no cuam tshuam rau qhov drilling ceev thiab kev ua haujlwm zoo.
