Reamers yog cov khoom tseem ceeb hauv cov txheej txheem reaming ntawm kab rov tav directional drilling rigs. Nyob rau hauv kab rov tav directional drilling siv, lub reamer yog lub cuab tam uas txiav thiab lov li tsim thiab av raws li coj trajectory. Kev loj hlob los ntawm lub qhov tsav mus rau qhov tsim nyog borehole txoj kab uas hla feem ntau yuav tsum muaj ntau theem reaming thiab ntau qhov kev mus ncig ua si rau kev tu lub qhov. nws tuaj yeem muab faib ua thoob, hniav, fly cutter, toothed, thiab cov menyuam reamersraws li cov yam ntxwv ntawm cov qauv.
1. Lub thoob Reamers
Lub thoob exerts ib co squeezing thiab phab ntsa-stabilizing nyhuv ntawm lub borehole phab ntsa thaum lub sij hawm reaming. Cov ntaub ntawv hnav-tiv taus welded rau sab nrauv ntawm lub thoob tuaj yeem tuav txoj kab uas hla thaum tseem kho cov phab ntsa borehole. Qhov kawg ntawm lub reamer yog welded nrog ib tug loj tapered conical nto ntawm tungsten carbide inserts, uas yog conducive rau rov qab reaming nyob rau hauv cov ntaub ntawv ntawm borehole vau.
Nws tseem tuaj yeem muab faib ua cov thoob thoob reamers thiab channeling thoob reamers. Lub tom kawg txais yuav ib tug kauv channel zawj, uas yog ntau conducive rau cov kua dej ntawm av nkos thiab cuttings. Tsis tas li ntawd, muaj cov hniav-bucket reamer, uas muaj cov yam ntxwv ntawm cov hniav loj ntawm cov hniav reamers, nrog rau kev sib tsoo, kho qhov borehole, thiab loj buoyancy cuam tshuam ntawm thoob reamers, nrog rau siab heev bore-enlarging efficiency.
2. Hniav Reamers
Nws cov qauv siv cov hniav loj loj rau kev txiav reaming. Qhov ntev reaming muaj li ntawm 480 mus rau 1625 hli, nrog rau txoj kab uas hla ntawm 71 mus rau 76 hli, thiab cov hniav suav ntawm 12, 20, 24, thiab lwm yam.
3. Fly Cutter Reamers
Fly Cutter Reamers: Siv carbide txiav inserts nrog interchangeable nozzles saum toj no. Reaming qhov ntev yog 480-1625 hli, dej txoj kab uas hla yog 76 hli, thiab cov hniav suav yog 12, 20, 24, thiab lwm yam.
4. Toothed reamers
Toothed reamers tsis muaj cov hniav ruaj khov lossis cov kabmob. Cov hniav tsim nyog thiab cov qauv bearing yuav tsum raug xaiv raws li cov qauv tsim sib txawv. Txais cov xibtes inclined thiab txias alloy hnav-tiv taus tsim, lawv muaj cov qauv tiv thaiv cov hniav-poob los tiv thaiv kev puas tsuaj thiab cov hniav poob, zam kev raug mob downhole. Lawv tsim nyog rau kab rov tav directional drilling siv nrog lub zog tsim, zoo hnav tsis kam, kev pab lub neej ntev, thiab kev nyab xeeb zoo. Reaming qhov ntev li ntawm 220 mus rau 1600 hli.
Zoo ib yam li cov roj drilling cov khoom, nws tuaj yeem muab faib ua milled-tooth thiab insert-tooth hom raws li qhov sib txawv iav log hom ntawm lub cev me ntsis.
(1) Milled-tooth reamers xa mus rau reamers siv cov hniav milled ntawm lub iav log lub cev, uas muaj kev hnav tsis zoo. Hard alloy txheej feem ntau welded rau lawv los txhim kho hnav tsis kam.
(2) Insert-tooth reamers xa mus rau cov reamers siv cov hniav ntxig, nrog cov hniav ua los ntawm cov hlau tawv tawv ntxig thiab tsau rau hauv lub iav log lub cev. Hom hniav no muaj qhov hardness siab thiab hnav tsis kam, nrog lub neej ua haujlwm ntev. Qhov tsis zoo yog qhov brittleness ntawm inserts, uas yog nquag mus puas thiab poob tawm vim xoob fixation.
5. Roller reamers
Roller reamerssiv loj-ntev kaw cov menyuam cutters nrog lub neej ntev tshaj 100 teev. Lawv muaj qhov tshwj xeeb ntau theem los tiv thaiv kev poob qis los tiv thaiv kev sib tsoo thaum lub sij hawm qhuav khiav thiab cov menyuam txiav cov vaj tse poob tawm thaum cov kabmob puas. Lawv kuj muaj zoo heev hydraulic tsim rau du cuttings tshem tawm thiab hydraulic pob zeb tawg. Cov khoom siv yog ua los ntawm cov hlau zoo hlau thiab cov kab loj loj siv cov qauv tsim los txo cov trajectory deformation. Reaming qhov ntev li ntawm 400 mus rau 2000 hli.
