Laum dab tshos yog cov hlau hnyav hnyav siv nyob rau hauv cov txheej txheem drilling los muab qhov hnyav ntawm lub laum me ntsis, stabilize lub laum txoj hlua, thiab xa torque mus rau me ntsis. Non-magnetic laum dab tshos (NMDCs) yog cov tho dab tshos ua los ntawm cov khoom tsis sib nqus xws li titanium lossis cov hlau tsis sib nqus. Lawv tau siv hauv kev ua haujlwm drilling qhov chaw sib nqus cuam tshuam los ntawm cov qauv sib nqus sib nqus tho dab tshos tuaj yeem cuam tshuam nrog cov ntsuas ntsuas ntsuas xws li magnetic resonance imaging (MRI) thiab cov cuab yeej electromagnetic logging.
Kev ua haujlwm ntawm Tsis-Magnetic Drill Collars:
1. Qhov hnyav thiab ruaj khov: Lub luag haujlwm tseem ceeb ntawm NMDCs yog muab qhov hnyav ntxiv thiab ruaj khov rau txoj hlua xyaum. Qhov hnyav pab thawb lub laum me ntsis rau hauv kev tsim, thaum qhov kev ruaj ntseg tiv thaiv txoj hlua laum los ntawm kev sib txawv ntawm txoj kev xav tau.
2. Corrosion Resistance: NMDCs yog tsim los ntawm cov khoom tsis sib nqus, uas kuj muaj cov khoom zoo corrosion kuj. Qhov no ua rau lawv zoo tagnrho rau siv hauv kev ua haujlwm drilling hauv qhov chaw corrosive.
3. Sib Nqus Sib Nqus: Tsis yog sib nqus laum dab tshos yog siv hauv kev ua haujlwm drilling qhov chaw sib nqus cuam tshuam tuaj yeem cuam tshuam nrog cov ntsuas ntsuas, xws li MRI thiab cov cuab yeej siv hluav taws xob.
Kev xaiv ntawm Non-Magnetic Drill Collars:
Thaum xaiv NMDCs, cov hauv qab no yuav tsum xav txog:
1. Khoom siv: Cov khoom siv rau NMDCs yuav tsum muaj lub zog zoo, ua haujlwm ntev, thiab tiv thaiv corrosion. Qee cov khoom siv feem ntau suav nrog titanium, aluminium, thiab cov hlau tsis sib nqus hlau.
2. Qhov hnyav: Qhov hnyav ntawm NMDC yuav tsum txaus los muab qhov tsim nyog qhov hnyav thiab ruaj khov rau txoj hlua xyaum.
3. Length: Qhov ntev ntawm NMDC yuav tsum yog qhov uas nws muab qhov hnyav txaus thiab ruaj khov rau txoj hlua xyaum thaum txo qis tag nrho ntev ntawm txoj hlua xyaum.
4. Hom kev sib txuas: Hom kev sib txuas ntawm NMDC yuav tsum sib haum nrog lwm cov khoom ntawm cov hlua tho, xws li cov khoom siv tho thiab cov kav dej tho.
5. Tus nqi: Tus nqi ntawm NMDC yuav tsum raug txiav txim siab raws li lawv feem ntau kim dua li cov khoom siv sib nqus sib nqus. Txawm li cas los xij, tus nqi ntawm kev siv NMDCs tuaj yeem tsim nyog hauv kev ua haujlwm drilling qhov chaw sib nqus cuam tshuam yuav ua rau muaj teeb meem loj.
Zuag qhia tag nrho, tsis yog-magnetic laum dab tshos yog cov cuab yeej tseem ceeb hauv kev ua haujlwm niaj hnub drilling, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas sib nqus cuam tshuam tuaj yeem cuam tshuam cov ntsuas ntsuas. Kev xaiv kom raug thiab siv NMDCs tuaj yeem pab ua kom muaj kev nyab xeeb thiab ua haujlwm zoo.
Tuam Tshoj Vigor's Laum dab tshos yog cov cuab yeej siv hnyav hnyav uas siv los ua kom pom tseeb qhov hnyav mus rau lub laum me ntsis rau drilling thiab ua kom cov hlua tho hauv qhov nro. Mill xeem daim ntawv pov thawj ua raws li API Spec. 7-1, NS-1, DS-1, thiab cov neeg siv khoom xav tau. Peb kuj tsim Slick Non-magnetic Drill dab tshos thiab Kauv Tsis-magnetic Drill dab tshos, lawv ua haujlwm ua vaj tse rau MWD cov cuab yeej thiab muab qhov hnyav rau txoj hlua drilling hauv kev taw qhia drilling.
Tuam Tshoj Vigor's Drill Collar cov ntaub ntawv suav nrog AISI 4145H, AISI4145H hloov kho hlau, thiab Tsis-sib nqus (P550 sib npaug, P530 sib npaug) Laum dab tshos yog Kauv Laum dab tshos, Slick, Flex, thiab Slip thiab / lossis of Elevator Recess.
Nta thiab Cov txiaj ntsig:
1. API kev ntxhov siab nyem groove pin txuas; API Bore Back Box Kev Sib Txuas.
2. Txias Rolling Thread cov hauv paus hniav - txhawm rau txhim kho kev qaug zog ntawm kev sib txuas.
3. Phosphate-coated kev sib txuas- tiv thaiv corrosion thiab galling raws li thawj zaug ua-up.
4. Lub hardness ntau ntawm 285 mus rau 341 BHN thiab Charpy cuam tshuam tus nqi ntawm 40 ft-lbs yog guaranteed ntawm tusyees faib 16 ntsiab lus nyob rau hauv tej seem ntawm chav tsev kub;
Tshwj xeeb nta:
1. Kauv Grooving- kom tsis txhob muaj qhov sib txawv ntawm qhov sib txawv hauv qhov.
2. Stress Relief Groove & Bore Back Box
3. Hardbanding yog tias xav tau.
4. Slip thiab of Elevator Recess-kom txhim kho downhole tuav efficiency thiab kev nyab xeeb.
Tuam Tshoj Vigor Drilling Roj Cov Cuab Yeej thiab Cov Khoom Siv Tuam Txhab Limited tau tsim nyob rau xyoo 2008. Vigor yog ib qho ntawm thawj cov tuam txhab lag luam uas tau qhia Suav cov cuab yeej downhole rau lub lag luam thoob ntiaj teb. Vigor nkag siab tias qhov ua tau zoo txhais tau li cas rau kev lag luam roj thiab roj, thiab nws muaj txiaj ntsig npaum li cas rau kev txuag cov nqi ntawm cov khoom, tshwj xeeb tshaj yog lub sijhawm nyuaj thiab tsis tau muaj dua los rau lub ntiaj teb no.
