Taw Qhia Ntawm Hardbanding
Hardbanding yog hnav-resistant metallic txheej Hardbanding yog txheej txheem ntawm nteg on ib txheej los yog nto ntawm cov hlau tawv] ntawm ib tug softer hlau ib feem. Siv los ntawm cov pa roj hlau arc vuam rau ntawm qhov chaw sab nraud ntawm cov tho yeeb nkab cov cuab yeej pob qij txha txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws
Hardbanding yog siv rau qhov kev sib hloov thiab axial kev sib txhuam cuam tshuam nrog drilling thiab tripping tsim ntau abrasive hnav ntawm txoj hlua laum thiab lub casing lossis nruab nrab ntawm txoj hlua tho thiab pob zeb. Hard alloy overlays yog siv rau cov ntsiab lus ntawm kev sib cuag loj tshaj plaws. Feem ntau, lub hardbanding yog siv rau cov cuab yeej sib koom ua ke vim nws yog qhov dav tshaj plaws ntawm txoj hlua tho thiab yuav ua rau kev sib cuag nrog lub casing feem ntau.
Thaum pib, tungsten-carbide hais tau muab tso rau hauv ib qho me me-hlau matrix, tshuav tus qauv kev lag luam rau ntau xyoo. Txawm li cas los xij, cov tswv zoo tsis ntev los no pom tau hais tias thaum lub cuab yeej sib koom ua ke tau tiv thaiv zoo, cov khoom siv tungsten-carbide feem ntau ua raws li cov cuab yeej txiav tawm tsam lub casing, ua rau muaj kev hnav hnyav thiab qee zaus tag nrho cov casing tsis ua haujlwm. Txhawm rau hais txog qhov xav tau tseem ceeb rau cov khoom siv tawv tawv tawv uas tuaj yeem tiv thaiv cov pob qij txha thiab lwm yam cuab yeej downhole.
Hom hardbanding:
1. Tsau hardbanding (PROUD)
2. Flush hardbanding (FLUSH)
3. Hardbanding ntawm lub hauv paus chim siab ntawm Drill Collar thiab Heavy Weight Drill Pipe
Hardbanding muaj nuj nqi:
1. Tiv thaiv cov tho yeeb nkab cov cuab yeej sib koom ua ke tiv thaiv kev puas tsuaj thiab hnav thiab txuas ntxiv DP kev pab cuam lub neej.
2. Tiv thaiv cov cuab yeej pob qij txha tiv thaiv thermal tawg.
3. Txo qhov hnav khaub ncaws.
4. Txo qhov drilling kev sib txhuam poob.
5. Hardbanding tso cai rau kev siv slim OD welded cuab yeej pob qij txha.
Kev siv Hardbanding:
1. Hardbanding muaj feem xyuam rau kev xyaum cov kav dej ntawm txhua qhov ntau thiab tsawg.
2. Hardbanding tej zaum yuav siv tau rau cov tshiab thiab u sed tubular.
3. Hardbanding tuaj yeem siv rau ntawm cov yeeb nkab laum cov cuab yeej pob qij txha ua raws li GOST R 54383-2011 thiab GOST R 50278-92 lossis ib qho kev qhia tshwj xeeb ntawm lub teb chaws cov yeeb nkab mills, thiab ntawm cov yeeb nkab laum cov cuab yeej sib txuas ua raws API Spec 5DP.
4. Hardbanding tuaj yeem siv rau ntawm cov kav dej laum nrog ntau hom kev sib koom ua ke, suav nrog ob lub xub pwg cov cuab yeej pob qij txha.
5. Hardbanding tuaj yeem siv rau ntawm cov kav dej txias-resistant laum thiab qaub-kev pabcuam DP.
Hardbanding tuaj yeem siv rau ntawm tubular ntawm cov hauv qab no thiab ntau thiab tsawg:
1. Cov yeeb nkab lub cev OD 60 mus rau 168 hli, ntev txog 12 m, OD ntawm cov cuab yeej welded pob qij txha ib DP cov ntaub ntawv.
2. Hardbanding yog siv rau kev ntxhov siab ntawm HWDP, ntawm cov cuab yeej sib koom ua ke ntawm HWDP, thiab DC ntawm txhua hom thiab ntau thiab tsawg.
3. Hardbanding kuj tseem siv rau qhov kev chim siab ntawm HWDP thiab DC.
4. Hardbanding tuaj yeem siv rau ntawm cov cuab yeej sib txuas ua ntej lawv tau welded rau lub laum yeeb nkab.
Kev txuag tau tsim los ntawm kev siv cov laum yeeb nkab nrog hardbanding:
1. Drill yeeb nkab kev pab cuam lub neej txuas ntxiv mus txog 3 zaug.
2. Cov cuab yeej sib koom ua ke yog txo los ntawm 6-15% nyob ntawm seb hom hardbanding siv.
3. Casing phab ntsa hnav yog txo los ntawm 14-20% piv rau hnav los ntawm cov cuab yeej siv pob qij txha.
4. Txo qhov kev sib txhuam zoo.
5. Yuav tsum tau rotary torque txo, yog li txo lub zog noj.
6. Txhim kho kev ua haujlwm drilling.
7. Txo lub sijhawm drilling.
8. Txo qhov zaus ntawm txoj hlua laum thiab cov hlua casing tsis ua haujlwm hauv kev ua haujlwm drilling.
