Tricone Bit VS PDC ntsis, Qhov twg yog qhov kev xaiv zoo tshaj rau koj?
Tricone Bit VS PDC ntsis, Qhov twg yog qhov kev xaiv zoo tshaj rau koj?
Lub laum me ntsis yog ib qho cuab yeej los laum lub qhov cylindrical (wellbore) kom pom thiab rho tawm cov roj av thiab cov roj ntsha.
Hauv kev lag luam roj thiab roj, nws yog ib qho tseem ceeb kom muaj cov cuab yeej zoo rau txhua qhov ntawm koj qhov project. Kev siv cov cuab yeej tsis raug tuaj yeem ua rau muaj kev puas tsuaj, yog li nws tseem ceeb heev kom muaj cov ntaub ntawv raug ua ntej koj pib. Tricone cov khoom thiab PDC laum khoom yog muaj nyob rau hauv kev lag luam roj thiab roj. Tricone Bit VS PDC Bit, Qhov twg yog qhov kev xaiv zoo tshaj rau koj?
Tricone Bit hauv Kev Lag Luam Roj thiab Roj
Lub tricone me ntsis tau tsim los ntawm Hughes engineer thiab Ralph Neuhaus thiab yog ib qho kev hloov ntawm Baker Hughes thawj ob lub khob hliav qab. Ib qho tricone me ntsis yog ib lub laum me ntsis nrog lub taub hau uas tau muab faib ua peb qhov tseem ceeb. Lub tricone me ntsis muaj peb rotating cones ua hauj lwm nyob rau hauv ib leeg nrog nws kab ntawm txiav hniav. Cov menyuam-cone khoom yog siv los laum formations los ntawm mos mus rau tawv. Cov txheej txheem mos siv cov hniav hlau thiab cov tawv siv tungsten carbide.
Qhov txiaj ntsig loj tshaj plaws ntawm cov khoom siv tricone muaj tshaj lwm yam kev xyaum yog qhov kev sim ntawm lub sijhawm. Lawv tau raug tshuaj xyuas ntau zaus los ua pov thawj tias lawv yog qhov zoo tshaj plaws ntawm kev tswj cov xwm txheej nyuaj. Tricones 'muaj peev xwm los daws ob qho tib si mos thiab tawv tsim ua rau lawv yooj yim dua uas lwm cov khoom siv tho tsis muaj.
PDC Bit hauv Kev Lag Luam Roj thiab Roj
PDC cov khoom tau txais lawv lub npe los ntawm polycrystalline pob zeb diamond compacts siv rau lawv cov qauv txiav. PDC me ntsis yog ib lub laum me ntsis haum nrog cov pob zeb diamond cutters es tsis txhob siv cov hniav hlau.
PDC cov khoom tau tsim nyob rau xyoo 1970s thiab tau los ua ib qho ntawm cov khoom siv nrov tshaj plaws hauv ntiaj teb. Cov qauv tsim nta lub taub hau ruaj khov thiab yog tsim los ntawm kev sib txuas cov pob zeb diamond thiab tungsten carbide nrog kub thiab siab. PDC cov khoom xyaum nrawm dua tricone cov khoom thiab zoo heev ntawm shearing pob zeb, txawm hais tias ob qho tib si tricone cov khoom thiab PDC cov khoom muaj cais qhov chaw hauv kev lag luam drilling. Qhov tseeb PDC tsim muaj xws li spiraled lossis asymmetric cutter layouts, gauge rings, thiab hybrid cutter designs.
Txawm hais tias PDC cov khoom tau dhau los ua neeg nyiam, cov khoom siv tricone tseem sway ntau yam sib txawv drilling. Cov no suav nrog pob zeb, dolomite, thiab limestone nyuaj. Txij li thaum cov kev hloov pauv rau PDC tsis cuam tshuam txog kev txaus siab hauv cov cheeb tsam ntawd, tricone cov khoom yuav tuav cov thawj coj mus ntev.
Qhov txawv yog dab tsi?
Qhov ncaj tshaj qhov sib txawv ntawm ib qho tricone me ntsis thiab PDC laum me ntsis yog tsis muaj qhov txav ntawm PDC Bit.
Tricone khoom muaj peb lub cones (tsav qhov chaw), thiab lawv yuav tsum tau lubricated bearings thiab roj reservoir. Thaum cov khoom siv tricone siv rau hauv cov haujlwm loj, nws yuav tsum tau muaj lub foob kom cov drillers tuaj yeem khaws cov khib nyiab los ntawm kev ua rau muaj kev cuam tshuam hauv kev sib hloov.
PDC taag cutter khoom yog cov khoom thiab tsis muaj qhov txav txav. PDC cov khoom yog tsim los ntawm kev sib txuas cov pob zeb zoo nkauj zoo nkauj thiab tungsten carbide nyob rau hauv qhov kub thiab txias heev.
PDC & Tricone txiav hom yog txawv thiab. PDC txiav cov pob zeb thaum tricone crushes.
Tricone ntsis yuav tsum muaj WOB siab dua kom ua tau zoo. Txwv tsis pub, nws cov ntaub ntawv tuaj yeem hnav ua ntej.
Cov ntsiab lus:
PDC me ntsis yog qhov kev xaiv zoo rau qee qhov kev tsim. PDC cov khoom ua haujlwm zoo hauv cov pob zeb sib xyaw, homogeneous, xws li shale, sandstone, limestone, xuab zeb, thiab av nplaum. Thaum koj ua haujlwm nrog cov pob zeb hais saum toj no, koj tuaj yeem sim PDC me ntsis raws li kev daws teeb meem ceev, nyab xeeb, thiab kev lag luam. Txwv tsis pub, Tricone yog koj qhov kev xaiv zoo tshaj plaws.
