Dab tsi yog Downhole Stabilizer?
Lub ntsiab lus ntawm downhole stabilizer
Lub downhole stabilizer yog ib hom ntawm downhole chaw siv nyob rau hauv lub hauv qab qhov sib dhos ntawm ib tug laum hlua. Nws mechanically stabilizes lub hauv qab qhov sib dhos nyob rau hauv lub borehole nrog lub hom phiaj kom tsis txhob unintentional sidetracking, thiab vibrations, thiab xyuas kom meej qhov zoo ntawm lub qhov yog drilled. Nws yog tsim los ntawm lub cev hollow cylindrical thiab stabilizing hniav, ob qho tib si ua los ntawm cov hlau muaj zog. Cov hniav tuaj yeem yog ncaj los yog spiraled thiab nyuaj-ntsej muag nrog cov carbide puas rods thiab carbide hnav inserts rau hnav tsis kam.
Hom ntawm downhole stabilizer
Muaj peb hom drilling stabilizers siv hauv kev lag luam oilfield.
1. Lub stabilizer tseem ceeb yog tag nrho machined tawm ntawm ib daim hlau. Hom no nyiam ua tus qauv thiab tau siv dav.
Cov hniav ntawm cov hniav stabilizer yog ib qho tseem ceeb ntawm lub cev stabilizer. Thaum twg lub stabilizer tau hnav mus rau qhov tsis txaus ntseeg, tag nrho cov stabilizer raug xa mus rau lub khw rau kev kho dua tshiab. Qhov no yog tsim rau tawv thiab abrasive formations. Nws yog siv rau hauv qhov me me qhov ntau thiab tsawg
2. Lub tes tsho Replaceable stabilizer, qhov twg cov hniav nyob rau ntawm lub tes tsho, uas yog ces screwed rau ntawm lub cev. Hom no tuaj yeem txuag tau nyiaj thaum tsis muaj chaw kho vaj tse nyob ze ntawm qhov dej drilled. Lawv muaj xws li mandrel thiab lub tes tsho kauv. Thaum cov hniav hnav tawm, lub tes tsho tuaj yeem yooj yim tshem tawm ntawm lub mandrel ntawm lub rig thiab hloov nrog lub tsho tshiab lossis lub tes tsho tshiab. Nws yog siv rau hauv qhov loj.
3. Welded blades stabilizer, qhov twg cov hniav yog welded rau ntawm lub cev. Hom no feem ntau tsis qhia txog cov roj qhov dej vim muaj kev pheej hmoo ntawm cov hniav ploj tab sis yog siv tsis tu ncua thaum drilling dej qhov dej los yog ntawm cov nqi qis.
Cov khoom siv hardfacing siv rau lub downhole stabilizer
Tungsten carbide yog kwv yees li ob zaug li tawv li hlau, thiab nws cov hardness tuaj yeem ncav cuag 94HRA. Vim nws cov hardness siab, nws yog ib qho khoom siv zoo heev rau hnav-resistant daim ntaub ntawv, nrog rau hardfacing. Tungsten carbide hardfacing muaj qib siab tshaj plaws ntawm kev puas tsuaj. Qib siab ntawm kev puas tsuaj yog offset los ntawm kev cuam tshuam qis dua li lwm hom hardfacing.
Txhawm rau ua kom tau raws li qhov xav tau tshaj plaws drilling, ZZBetter muaj ntau qhov ntau thiab tsawg thiab cov duab ntawm tungsten carbide inserts rau qhov nyuaj-facing nyob rau hauv ntau yam kev xaiv rau koj stabilizers. Txhua carbide insert yog haum rau koj cov kev xav tau tshwj xeeb, thiab peb daim ntawv thov kws tshaj lij ua kom muaj kev tiv thaiv tshwj xeeb rau kev hnav thiab tsim kua muag, ua kom lub neej ntev ntawm koj cov stabilizers. Xws li HF2000, geothermal hard-facing siv tungsten carbide cib, brazed rau stabilizer hniav thiab ncig los ntawm tungsten impregnated composite pas nrig; HF3000, Ib txoj kev nyuaj-ntsig uas siv qhov siab tshaj plaws ntawm cov hwm tungsten carbide ntawm txhua qhov hnav. Nws tuaj yeem siv rau hauv ntau yam thicknesses thiab siv tungsten carbide inserts los ua kom muaj zog thiab cuam tshuam ntev.
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.
