Raws li cov txheej txheem khaws cia, cov khoom siv ntawm cov khoom tsis yog - sib nqus laum dab tshos feem ntau tsis hloov pauv tseem ceeb tom qab ib xyoos ntawm kev khaws cia. Txawm li cas los xij, nws yog ib qho tseem ceeb los xyuas kom meej qhov chaw qhuav tsis muaj corrosive gases thiab ua kom muaj kev tiv thaiv xeb tsis tu ncua.
Hauv kev ua haujlwm drilling, tsis yog - sib nqus laum dab tshos yog cov cuab yeej tseem ceeb, thiab kev ruaj khov thiab kav ntev ntawm lawv cov khoom ncaj qha cuam tshuam rau kev ua haujlwm drilling thiab kev nyab xeeb. Yog li ntawd, ntau tus neeg siv tau txhawj xeeb txog seb cov khoom siv ntawm cov khoom tsis yog- sib nqus laum dab tshos yuav hloov tom qab ntev - lub sijhawm cia. Peb tau ua ib qho kev sib tham hauv - qhov tob tob ntawm cov lus nug, "Puas yog cov khoom siv tsis yog- cov hlua hlau nplaum hloov pauv tom qab ib xyoos ntawm kev cia?"
Kev tshuaj xyuas cov yam ntxwv ntawm cov khoom tsis yog -Magnetic Drill Collars
Tsis yog- cov hlua sib nqus hlau nplaum feem ntau yog ua los ntawm cov khoom tsis yog- cov khoom sib nqus, xws li austenitic stainless hlau. Cov ntaub ntawv no muaj zoo heev corrosion kuj thiab mechanical zog. Tsis yog- cov khoom sib nqus yog qhov tseem ceeb rau lawv qhov kev ua tau zoo hauv qhov chaw drilling tshwj xeeb (xws li kev txiav cov haujlwm uas yuav tsum tau zam kev cuam tshuam ntawm magnetic teb). Tsis tas li ntawd, cov tsis yog - sib nqus laum dab tshos yuav tsum muaj lub zog siab thiab tawv kom tiv taus cov kev ntxhov siab thiab kev cuam tshuam uas tshwm sim thaum lub sijhawm drilling.
Qhov cuam tshuam ntawm Cia ib puag ncig ntawm cov khoom tsis yog -Magnetic Drill Collars
Qhov chaw cia khoom yog qhov tseem ceeb cuam tshuam rau kev ruaj ntseg ntawm cov khoom tsis yog- cov khoom siv sib nqus sib nqus. Feem ntau, tsis yog- cov hlua sib nqus sib nqus yuav tsum tau muab cia rau hauv qhov chaw qhuav, zoo- qhov cua qhov chaw tsis muaj roj corrosive. Cov av noo ntau dhau los yog muaj cov roj corrosive tuaj yeem ua kom cov txheej txheem kev laus thiab corrosion ntawm cov khoom. Qhov kub hloov pauv kuj tseem muaj qee qhov cuam tshuam rau cov khoom siv, tab sis qhov no tsis tshua muaj txiaj ntsig piv rau cov av noo thiab corrosive gases.
Material Aging Mechanisms thiab Kev Tiv Thaiv Kev Ntsuas
Kev laus ntawm cov khoom tsis yog- cov khoom siv hlau nplaum sib nqus feem ntau tshwm sim raws li qhov chaw corrosion, kev hloov hauv cov qauv sab hauv, thiab kev poob ntawm cov khoom siv kho tshuab. Txhawm rau tiv thaiv cov khoom laus, cov neeg siv tuaj yeem siv cov kev tiv thaiv hauv qab no:
1. Khaws ib puag ncig kom qhuav: Siv cov desiccants lossis dehumidifiers los tswj cov av noo ntawm qhov chaw cia.
2. Tsis txhob corrosive gases: xyuas kom qhov chaw cia nyob deb ntawm cov nroj tsuag tshuaj thiab lwm qhov chaw uas yuav tsim corrosive gases.
3. Kev tiv thaiv xeb tsis tu ncua: Siv cov tshuaj tiv thaiv xeb kom tsim nyog los kho qhov chaw ntawm qhov tsis yog - sib nqus laum dab tshos kom tiv thaiv qhov xeb.
4. Kev Tshawb Fawb thiab Kev Saib Xyuas Tsis tu ncua: Kev tshuaj xyuas tsis tu ncua ntawm cov tsis yog -Magnetic laum dab tshos txhawm rau txheeb xyuas thiab daws cov teeb meem uas yuav tshwm sim.
Kev sim cov ntaub ntawv thiab kev lag luam kev lag luam: Raws li kev sim cov ntaub ntawv thiab kev lag luam kev lag luam, cov khoom siv ntawm cov khoom siv tsis yog - sib nqus laum dab tshos feem ntau tsis hloov pauv ntau tom qab ib xyoos ntawm kev khaws cia raws li cov txheej txheem. Txawm li cas los xij, qhov no tsis tau txhais hais tias qhov cuam tshuam ntawm qhov chaw cia khoom ntawm cov khoom tuaj yeem tsis quav ntsej kiag li. Ntawm qhov tsis sib xws, cov neeg siv yuav tsum nruj me ntsis ua raws li qhov yuav tsum tau khaws cia kom ntseeg tau tias cov khoom ruaj khov thiab ua haujlwm ntev ntawm cov khoom tsis yog - sib nqus laum dab tshos.
