Roj Casing Steel Qib Analysis: Xaiv txoj cai "Armor" rau koj Qhov Zoo
Hauv kev lag luam roj thiab roj, lub qhov dej zoo li "steel tunnel" tob rau hauv lub ntiaj teb. Covvaj huam sib luagua raws li cov cuab yeej tiv thaiv lub qhov. Los ntawm qhov tob tob ntawm ob peb puas meters mus rau qhov tob reservoir ntau tshaj 7,000 meters, lub casing yuav tsum tiv thaiv loj heev geological siab thiab corrosive kua.
Qhov zais cia rau qhov kev tiv thaiv no yog nyob hauvQib Steel. Raws li API 5CT cov qauv, qib qhia cov khoom ua haujlwm. Piv txwv li,N80txhais tau hais tias qhov tsawg kawg nkaus yield zog yog80,000 psi(kwv yees . 552 MPa).
NtawmGnee Steel, peb tshwj xeeb hauv kev muab ntau yam API 5CT raws li OCTG (Oil Lub Tebchaws Tubular Khoom) kom ntseeg tau tias koj cov dej num drilling nyob twj ywm muaj kev nyab xeeb thiab ua haujlwm tau zoo.
Los ntawm "Bronze" mus rau "King": 7 Qib ntawm Casing Performance
Ib puag ncig sib txawv xav tau qhov sib txawv "kev txawj ntse." Nov yog yuav ua li cas peb faib cov qib casing raws li lawv lub zog thiab daim ntawv thov:
Yield zog:~ 276 MPa (40,000 psi).
Nta:Basic carbon steel nrog tus nqi qis tshaj.
Qhov zoo tshaj plaws rau:Cov dej ntiav ntiav lossis -cov roj qhov dej siab. Nws yog "lub hauv paus T-shirt" ntawm lub ntiaj teb casing.
Yield zog:~ 379 MPa (55,000 psi).
J55 vs K55:Thaum lawv sib koom tib lub zog,K55muaj kev cuam tshuam zoo zog thiab siab purity siab dua li J55.
Qhov zoo tshaj plaws rau:1,000-2,000m lub qhov dej. Lawv yog cov feem ntau xaiv rau nto casing.
Nov yog qhov tshwj xeeb "cov ntoo txuj ci" tshwm sim. Ob leeg muaj lub zog tawm los ntawm ~ 552 MPa, tab sis lawv cov temperaments txawv:
N80 (N80-1/N80-Q):Lub ntsiab quab yuam rau 3,000-4,000m pa qhov tob tob.
L80 Series (Anti-Cov Kws Tshaj Lij Choj corrosion):
L80-9Cr & L80-13Cr:Infused nrog Chromium los tiv thaivCO2 corrosion.
Super 13Cr:Qhov kawg daim thaiv tiv thaiv ob leegH2S thiab CO2nyob rau hauv lub qhov dej qaub.
Gnee Steel Pro Lub Tswv Yim:Kev nqis peev hauv L80-13Cr tej zaum yuav yog tus nqi siab dua, tab sis nws tiv thaiv kev puas tsuaj tsis zoo nyob rau hauv ib puag ncig acidic, txuag ntau lab tus nqi kho.
Siab - Qib Ua tau zoo rau cov xwm txheej hnyav
C90/C95:Tsim los rau siab - lub siab roj qhov dej nrog zoo heevcev qhuav dej tsis kam.
T95:Tshwj xeeb optimized rauSSC (Sulfide Stress Cracking)kuj nyob rau hauv hnyav H2S ib puag ncig.
Yield zog:~ 758 MPa (110,000 psi).
Nta:Siab -lub zog quenched thiab tempered steel.
Qhov zoo tshaj plaws rau:Ultra- qhov dej tob (tshaj 4,000m) thiab siab - qhov dej siab. Nws yog "alloy armor" ntawm lub oilfield.
Yield zog:~862 MPa (125,000 psi).
Nta:"Ceiling" ntawm API 5CT system.
Daim ntawv thov:Siv rau qhov nyuaj tshaj plaws, siab - kub, thiab siab - siab (HTHP) qhov dej uas zoo tib yam hlau yuav tsuas tsoo los yog snap.
Yuav Ua Li Cas Xaiv Cov Qib Zoo rau Koj Qhov Haujlwm?
Kev xaiv tsis yog hais txog kev xaiv "theem siab tshaj"; nws yog hais txog lubzoo meej match:
Qhov tob:Cov qhov dej ntiav siv J55; Qhov dej tob xav tau P110.
Corrosion:Yog tias H2SH2S lossis CO2CO2 tam sim no, kojyuav tsumhloov mus rau L80 lossis T95.
Siab:Cov qib siab -collapse (C90/T95) yog qhov tseem ceeb rau cov txaj ntsev hnyav lossis siab - thaj chaw roj av siab.
Gnee Steelmuab ntau tshaj li cov kav dej. Peb muab kev cob qhia kev xaiv cov khoom siv los xyuas kom meej tias koj lub casing ua tau raws li API 5CT cov qauv thaum nyob hauv pob nyiaj siv. Los ntawm theem pib J55 mus rau hwm Q125, peb cov khoom raug kuaj xyuas ultrasonic thiab hydrostatic.
Vim li cas Gnee Steel?
Raws li tus thawj coj OCTG muab khoom,Gnee Steelnkag siab tias kev nyab xeeb yog qhov tseem ceeb tshaj plaws hauv kev lag luam roj.
Certified Quality:Ua raws li API 5CT, ISO 9001, thiab thib peb -kev soj ntsuam tog (SGS/BV).
Kev cai daws teeb meem:Peb muab ntau hom xov (STC, LTC, BTC, thiab Premium Connections) thiab hnyav - phab ntsa tsim.
Ntiaj teb no Logistics:Kev xa khoom zoo mus rau cov chaw tseem ceeb roj thoob ntiaj teb.
