Lub reamer yog ib feem tseem ceeb ntawm kab rov tav directional drilling tshuab nyob rau hauv tus txheej txheem ntawm reaming. Nyob rau hauv kev tsim kho ntawm kab rov tav directional drilling, nws yog ib qho cuab yeej los txiav thiab tawg cov av thiab pob zeb raws li txoj kev taug. Kev nthuav dav los ntawm qhov kev qhia lub qhov mus rau qhov haum lub qhov taub feem ntau yuav tsum muaj ntau theem reaming thiab ntau yam clearing. Nws tuaj yeem muab faib ua lub thoob reamer, phaj reamer, ya-rotating reamer, iav reamer,cov menyuam reamer,thiab lwm yam raws li cov yam ntxwv ntawm cov qauv.
1. Barrel reamer
Barrel reaming txheej txheem ntawm lub qhov phab ntsa muaj qee qhov nyem, thiab phab ntsa stabilization muaj nuj nqi. Vuam cov khoom siv-resistant rau sab nrauv ntawm lub thoob tuaj yeem khaws txoj kab uas hla thiab kho cov phab ntsa zoo. Nws lub nraub qaum npog yog welded nrog tungsten carbide-tipped cutter lub taub hau nrog lub taper loj, uas yog qhov zoo rau qhov zoo reaming nyob rau hauv qhov opposite kev taw qhia nyob rau hauv cov ntaub ntawv ntawm lub cev qhuav dej.
Lub thoob reamer kuj tseem tuaj yeem muab faib ua thoob thoob thiab cov thoob thoob reamer, tom kawg tau txais kev sib tw khiav groove, uas yog qhov zoo dua rau cov channelization ntawm av nkos thiab cov khib nyiab geotechnical. Tsis tas li ntawd, muaj lub phaj thoob reamer, uas muaj cov yam ntxwv ntawm qhov loj txiav ntug ntawm lub phaj hom tab sis kuj muaj lub luag haujlwm ntawm lub thoob reamer ntawm lub qhov phab ntsa ntawm qhov kev kho extrusion thiab lub luag hauj lwm ntawm buoyancy loj, nthuav lub qhov. efficiency yog siab heev.
2. Phaj reamer
Nws cov cuab yeej lub cev qauv txais cov kev txiav loj loj, uas tuaj yeem paub txog qib reaming. Lub qhov loj ntawm 480 ~ 1625mm, thiab lub qhov taub dej yog 71 ~ 76mm, cov lej 12, 20, thiab 24 muaj xws li.
3. Flying Spin Reamer
Nws txais cov cemented carbide txiav cov hniav, thiab cov nozzles ntsia saum toj no yog sib hloov. Reaming loj ntawm 480-1625mm, dej qhov muag txoj kab uas hla ntawm 76 hli, tus naj npawb ntawm 12, 20, 24, thiab hais txog.
4. Iav Reamer
Lub iav reamer tsis muaj cov hniav ruaj khov thiab cov kabmob, yog li nws yog ib qho tsim nyog yuav tau xaiv cov hniav uas tsim nyog thiab cov kabmob raws li cov qauv sib txawv. Nws siv lub xib teg rov qab tilting, txias-set los tiv thaiv hnav alloy tsim, thiab cov hniav log los tiv thaiv kev tawg, uas feem ntau tiv thaiv cov hniav log ntawm dislodging tom qab cov hniav log bearing puas, ua rau muaj xwm txheej hauv lub qhov. Nws yog tsim rau kab rov tav directional drilling siv thiab yog tsim los nrog lub zog siab, zoo hnav tsis kam, kev pab lub neej ntev, thiab kev ruaj ntseg zoo. Lub qhov reaming loj yog 220 ~ 1600mm.
Nws feem ntau yog siv tib tus hniav xibtes thiab cov hniav log ntawm cov hniav log tho me ntsis raws li 1 txiav ntug, thiab tus naj npawb ntawm cov npoo yog 3 thiab siab dua, lub qhov reamer yog tsim los ntawm lub phaj txhawb nqa, rear baffle, mandrel, pem hauv ntej baffle. , pem hauv ntej txhawb lub nplhaib, pem hauv ntej txhawb phaj, hniav log, hniav xibtes thiab lwm yam. nws siv cov txheej txheem vuam los txuas thiab kho txhua yam. Cov txheej txheem reaming yog muab los ntawm cov ntsia hlau drilling cuab yeej los muab torque thiab lub drilling rig los muab nro.
Zoo ib yam li roj drilling, nws tuaj yeem muab faib ua milled daim duab, inlaid raws li ntau hom kev xyaum lub cev.
(1) Milling iav reamer
Nws yog kev siv cov hniav ntawm cov iav yog milled cov hniav, uas yog, nyob rau hauv cov hniav log matrix milled hniav, nws hnav kuj tsis zoo. Txhawm rau txhim kho qib ntawm kev hnav tsis kam, feem ntau welded ntawm nws cov txheej tawv tawv.
(2) Iav Reamer
Nws hardness, thiab hnav tsis kam yog qhov zoo, kev pab lub neej ntev. Qhov tsis zoo yog tias cov hniav yog nkig, yooj yim rau lub cev, thiab poob tawm vim cov hniav inlaid tsis ruaj ntseg.
5. Cov menyuam reamer
Roller Reameradopts ib txoj kab uas hla loj hlau sealing hob tsim, bearing lub neej txog li 100 teev los yog ntau tshaj. Lub cim multi-theem anti-dislodgement interlocking ntaus ntawv tiv thaiv kev tawg thaum lub laum me ntsis pov tseg thiab dislodgement ntawm lub hob plhaub thaum cov kabmob puas. Meanwhile, nws muaj ib tug zoo heev hydrodynamic tsim, du slag paug, thiab hydraulic pob zeb tawg. Lub laum me ntsis yog precision forged nrog high-zoo alloy steel, thiab lub laum loj me lub cev txais qhov hnyav hnyav-txo tsim los txo cov kev deformation. Qhov seem loj yog 400 ~ 2000mm.
Cov yam ntxwv ntawm ntau hom reamers txiav txim siab txog kev ua haujlwm reaming, kev siv, thiab daim ntawv thov, ntawm cov thoob reamer, phaj, thiab ya-rotating yog tsim rau traversing cov av txheej, thaum lub iav thiab cov menyuam pob zeb yog tsim rau traversing. lub pob zeb txheej. Nyob rau hauv kab rov tav directional drilling traversing project, tshwj xeeb tshaj yog nyob rau hauv ntev-ntev traversing project, lub stratum mob yog complex, thiab reamer adaptability rau lub stratum yog ib qho tseem ceeb heev.
◆ Kab rov tav directional drilling traversing pre-reaming yuav tsum xav txog peb yam nram qab no:
1. kev pab cuam lub neej ntawm cov reamer
2. tus nqi ntawm torque generated los ntawm reamer ntawm txhua theem reaming
3. efficiency thiab kev lag luam ntawm reaming.
Qhov zoo ntawm cov iav reamer xws li muaj zog geological adaptability, siab tsim lub zog, zoo hnav tsis kam, kev pab lub neej ntev thiab kev nyab xeeb kev ua tau zoo tuaj yeem txhim kho qhov ua tau zoo thiab zoo ntawm reaming, uas yog tsim rau kev siv mus ntev-kev taw qhia traversing. Yog li ntawd, nws yog ib qho tsim nyog yuav tau ua kom zoo dua thiab txhim kho cov iav reamer rau qhov ntev-ntev kab rov tav directional traversing tej yaam num.
