International qib sib npaug
J55 yog sib npaug rau lub teb chaws tus qauv 37Mn5 (GB / T 20659) thiab American standard AISI 1035 (ASTM A519), tab sis qhov tseeb muaj pes tsawg leeg yog txawv me ntsis. Piv txwv li, cov ntsiab lus manganese ntawm 37Mn5 yog siab dua (1.3% -1.6%), thaum cov ntsiab lus phosphorus ntawm J55 yuav tsum tau tswj nruj me ntsis hauv qab 0.03% (raws li tau teev tseg hauv API SPEC 5CT 2023 tsab).
Cov yam ntxwv ntawm J55
Qib Qeb Muaj Zog:J55 yog ib qho ntawm cov qib qis tshaj plaws hauv API tus qauv, muab kev ua haujlwm zoo thiab ua haujlwm tau zoo.
Kev xaiv nyiaj txiag:Vim tias cov ntsiab lus tsis tshua muaj alloy thiab qhov tseeb tias kev kho cua sov (xws li quenching thiab tempering) tsis yog qhov yuav tsum tau ua (feem ntau xa tuaj raws li -rolled condition), nws yog qhov kev xaiv pheej yig tshaj plaws.
Superior Weldability:Raws li qis-rau- nruab nrab carbon steel, J55 yooj yim heev rau vuam piv rau qib siab - lub zog.
Daim ntawv thov
Txoj Kev Loj Hlob Loj:Qhov zoo tshaj plaws rau cov roj thiab roj qhov dej nrog qhov tsim qis thiab qhov tob tob.
Nto Casing:Feem ntau siv rau sab saum toj - feem ntau txheej ntawm lub qhov dej los txhawb lub qhov thiab tiv thaiv thaj chaw dej tshiab.
Kev Tsim Kho Dej Dej:Siv dav hauv kev ua liaj ua teb thiab kev lag luam dej qhov dej vim nws tus nqi qis.
Coalbed Methane (CBM):Ib qho kev xaiv tseem ceeb rau CBM rho tawm qhov kev tsim cov siab feem ntau yog nruab nrab.
Thaum twg koj yuav tsum zam J55?
Yog tias koj qhov project cuam tshuam nrog ib qho ntawm cov xwm txheej hauv qab no, J55 yog qhov zoo liyuam kevxaiv:
High-Pressure Wells:Qhov twg yuav tsum muaj kev sib tsoo siab.
Sour Wells:MuajH2S(Koj yuav tsum xaiv qaub- qib kev pabcuam xws li L80-1, C90, lossis T95).
Deep Wells:Qhov twg cov yeeb nkab hlua hnyav tshaj qhov txwv tensile ntawm J55.
Critical Production Wells:Rau siab - qhov dej muaj txiaj ntsig, cov neeg ua haujlwm feem ntau hloov mus rau K55 lossis N80 kom ntseeg tau tias muaj kev nyab xeeb dua.

FAQ
J55 khoom yog dab tsi?
J55 roj casing feem ntau yog ua los ntawm cov pa roj carbon steel thiab tuaj yeem tiv taus siab, kub siab, thiab yaig los ntawm cov kua dej tsim thaum lub sijhawm drilling. Raws li cov kev xav tau sib txawv, J55 casing tuaj yeem muab faib ua ntau hom, xws li ca qhov kawg casing (LC), thickened casing (xws li STC, BTC, thiab lwm yam), thiab tshwj xeeb threaded casing (xws li VAM, REG, thiab lwm yam). Thickening kev kho mob tuaj yeem txhim kho lub zog tiv thaiv extrusion thiab tensile lub zog ntawm lub casing, ua kom muaj kev nyab xeeb ntawm kev ua haujlwm nyob rau hauv txoj haujlwm geological.
Lub zog tawm ntawm API 5CT J55 yog dab tsi?
J55 yog cov roj av casing steel qib uas tau teev tseg los ntawm American Petroleum Institute (API), uas yog cov qib siab - cov pa roj carbon zoo nrog lub zog tawm los ntawm 379-552MPa thiab lub zog tensile ntau dua lossis sib npaug rau 517MPa. Nws lub zog yog kwv yees li 30% siab dua li ntawm cov hlau zoo tib yam
