Hauv kev tsim thiab xaiv cov hlua laum, kev nkag siab txog kev xyaum tho dab tshos yog qhov tseem ceeb rau kev ua haujlwm zoo thiab kev ntseeg siab. Vigor qhia kev paub txog cov ntsiab lus alloys siv raunon-magnetic laum dab tshos- P550 thiab P530 nickel-tooj liab alloys.
P550 Tsis-Magnetic Laum dab tshos thiab P550 cov khoom siv
Raws li kev tshawb fawb thiab kev ua haujlwm ntawm tes, P550 tau dhau los ua cov khoom siv tseem ceeb rau cov ntawv thov tsis muaj hlau nplaum. Nws muaj kwv yees li 40% npib tsib xee, 1% titanium, 0.7% columbium, thiab qhov sib npaug ntawm tooj liab. Kuv tau pom cov hlau no muaj qhov tshwj xeeb ua ke ntawm lub zog, toughness, thiab cov khoom tsis sib nqus uas xav tau rau cov hlua tho. Cov ntsiab lus npib tsib xee siab muab P550 ua kom muaj zog zoo ntawm ib puag ncig 130 ksi yam tsis muaj kev cuam tshuam qhov hnyav. Qhov no txhais tau tias nws resists deformation nyob rau hauv hnyav loads thov nyob rau hauv drilling ua hauj lwm. Qhov ceev ntawm P550 yog 0.322 lb / in3 uas muab qhov hnyav-rau-ntsis yam tsis hnyav hnyav.
P550 khoom yog dab tsi?
Ib qho ntawm cov yam ntxwv tseem ceeb uas kuv txheeb xyuas thaum xaiv cov khoom yog sib nqus permeability. P550 muaj qhov txheeb ze permeability ntawm 1.01, txhais tau tias nws tsis cuam tshuam nrog cov cuab yeej tseem ceeb ntawm cov cuab yeej drilling uas siv cov hlau nplaum los txiav txim siab kev taw qhia. Nws cov hluav taws xob tiv taus ntawm ib ncig ntawm 500 ohm-cm kuj tseem tiv thaiv cov xau tam sim no uas tuaj yeem cuam tshuam kev ntsuas los ntawm EM-raws li cov cuab yeej. Tom qab ntsuas ntau cov alloys, kuv tau pom tias P550 muab qhov zoo tshaj plaws sib npaug ntawm lub zog, qhov hnyav, thiab cov khoom tsis sib nqus.
Raws li kuv cov kev tshawb fawb rau hauv nws cov metallurgy, cov khoom ntawm P550 yog los ntawm kev ceev faj tswj ntawm thermomechanical processing thiab nag lossis daus-hardening tshav kub kho. Cov npib tsib xee thiab tooj liab tsim ib qho kev daws teeb meem matrix, thaum ntxiv ntawm titanium thiab columbium pab tswj cov qauv nplej. Cov kev kho cua sov tshwj xeeb Kuv tau sim tsim cov xim zoo nkauj uas pab cuam tshuam kev txav txav, yog li ua kom lub zog thiab tawv. Qhov kev nkag siab ntawm yuav ua li cas P550 tau txais nws cov khoom zoo tshaj plaws pab kuv pom zoo rau kev kho cua sov specs thiab ntsuas kev tswj kom zoo.
P530 Tsis-Magnetic Laum dab tshos
Rau cov ntawv thov xav tau heev, qee zaum kuv pom zooP530 non-magnetic laum dab tshos. P530 muaj cov ntsiab lus nickel qis me ntsis nyob ib puag ncig 36% tab sis muaj kev sib piv. Hauv kuv qhov kev paub dhau los, P530 muab qhov qis dua lub zog thiab tawv, tab sis tuaj yeem muab kev txuag nqi hauv qhov chaw drilling tsawg dua. Ob leeg P550 thiab P530 ua tau raws li NACE cov qauv rau H2S tsis kam, uas yog qhov tseem ceeb rau kev tiv thaiv sulfide kev ntxhov siab tawg.
Txhawm rau kom ntseeg tau tias kuv nkag siab txog cov alloys no kom huv si, kuv ua qhov tseem ceeb kom ua raws li kev tshawb fawb tshiab. Qee cov ntaub ntawv tseem ceeb kuv siv suav nrog:
- Singh li al.'s ua haujlwm ntawm cov teebmeem ntawm kev kho cua sov ntawm microstructure thiab cov khoom ntawm P550. Qhov no tau ua rau kuv nkag siab txog kev ua kom zoo tshaj plaws los ntawm kev tsim precipitate rau lub zog thiab toughness.
- Feng li al. txoj kev tsom xam ntawm nag lossis daus theem hauv P550 thiab lawv cov txheej txheem ntxiv dag zog. Qhov no pab kuv zoo dua kwv yees tus cwj pwm alloy.
- Totten et al.'s overview of composition, properties, processing, and applications of non-magnetic drill collar alloys. Ib qho tseem ceeb qhia txog kev siv.
- ASTM B637 specification rau nickel alloys xws li P550 thiab P530 rau oilfield siv. Teem cov txheej txheem uas kuv ua raws li kev tswj xyuas kom zoo.
Nrog rau qhov tob ntawm kev paub kuv tau tsim los ntawm cov ntaub ntawv laum dab tshos, kuv tuaj yeem ua cov lus pom zoo kom ua tiav cov hom phiaj drilling. Kev nkag siab txog cov khoom siv hlau, cov khoom, kev ua, kev sim, thiab kev tsim nyog ntawm cov hlau tshwj xeeb no tso cai rau kuv los txhawb kev nyab xeeb, ua haujlwm zoo drilling. Kuv vam tias qhov kev pom thawj zaug no ua rau koj pom meej dua li casnon-magnetic laum dab tshoszoo li P550 thiab P530 tau ua kom zoo rau lawv lub luag haujlwm tseem ceeb hauv kev ua haujlwm drilling.
