Tsis paub tseeb:Nws yog qhov tseem ceeb los nco ntsoov tiasQeb Z150 tau muab tshem tawm los ntawm cov ntaub ntawv tshaj lij tshiab ntawm cov Upi 5CT tus qauv.Nws yog ib feem ntawm cov laus dua "Pawg 4" ultra {{1} - lub zog kawm, uas tseem muaj zom10. Thaum nws tseem yuav tau hais txog cov haujlwm tshwj xeeb lossis muaj los ntawm qee cov tuam txhab ua ib qho qauv, nws tsis yog tus qauv, tawm - cov khoom siv.
Cov ntaub ntawv no yog ua raws li cov ntaub ntawv keeb kwm thiab cov qauv qhia txog cov txheej txheem.
1. Cov yam ntxwv tseem ceeb & cov ntawv thov
Ultra - lub zog siab:Z150 yog tus cwj pwm los ntawm nws qhov tsawg kawg los lub zog ntawm 150,000 psi (1034 MPA). Qhov no ua rau nws yog ib qib muaj zog tshaj plaws ntawm cov casing muaj.
Daim Ntawv Thov:Nws tau tsim los siv rau hauvHuab Downhole ib puag ncig:
Ultra -} Cov dej tob tob:Qhov twg kev sib xyaw ua ke ntawm qhov hnyav nruj (txoj hlua tawv ntev) thiab siab sib dhos sib tsoo cov kev ntsuas xav tau siv lub zog tshwj xeeb.
Siab - h siab / siab- kub (HPHT) WELLS:Txhawm rau tiv thaiv lub cev loj loj hauv sab hauv tawg.
Cov qauv zoo tsim nyog:Xws li txuas ntxiv -}}} expring drilling (ERD) nrog lub siab dhia thiab lub zog.
Cov nyom:Ua tiav qhov muaj zog no yuav tsum tau sib kho me me thiab meej kho kom sov (quenching thiab tempering). Qhov no qee zaum tuaj yeem them tus nqi txo qis thiab muaj kev phom sij rau kev ntxhov siab sulfide (SSC). Yog li ntawd, nws yogFeem ntau tsis pom zoo rau Sour kev pabcuam(ib puag ncig muaj h₂s) tsis muaj kev sim txhij thiab kev hloov tshwj xeeb.
2. Cov khoom lag luam thiab cov cuab yeej siv tshuab cov cuab yeej
Cov lus hauv qab no qhia txog cov khoom tseem ceeb rau qib Z150 raws li nws tau txhais ua keeb kwm.
Rooj 1: Cov khoom siv kho tshuab ntawm API 5CT qib Z150
| Ntiag tug | Tus nqi | Ib yam | Sau ntawv | |
|---|---|---|---|---|
| Qib kev tsim | Z150 | - | "Z" Series rau Ultra -} lub zog siab | |

| Qhov Tshaj Tawm Los Muaj Zog | 180,000 (raug) | psi | 1241 MPa | (1) Qhov no yog qhov kev txwv ib txwm muaj; precise qhov tseem ceeb tau teev los ntawm cov khw. |
| Yam tsawg kawg tensile lub zog | 160,000 | psi | 1103 MPa | |
| Hardness (HRC) | ~ 36 - 42 | Hrc | * (2) Hardness tau thuam tau ua kom muaj zog thiab SSC tsis kam. | |
| Elongation (yam tsawg kawg nkaus) | Xws li cov mis | % | Cov qauv API txheej txheem raws li Tensile xeem cov hnoos qeev. |
Sau ntawv rau ntawm lub rooj:
Qhov siab tshaj plaws tau muaj zog:Qhov kev txwv siab tshaj plaws yog qhov tseem ceeb kom ua kom muaj kev lom zem ua tau zoo thiab du. Tus nqi tshwj xeeb yog feem ntau txhais los ntawm cov chaw tsim khoom cov ntawv txheej txheem cov ntaub ntawv.
Hardness:Qhov no yog qhov tseem ceeb heev. Siab Hardness Ntau txoj kev pheej hmoo ntawm sulfide kev ntxhov siab tawg (SSC). Rau qee qhov kev pab cuam hauv cov kev pab me me, lub hardness yuav xav tau kom zoo tswj thiab kuaj xyuas raws li tus qauv zoo li NACE MR0175 / ISO 15156.
3. Tshuaj lom neeg sib xyaw ua ke (raug / tus tswv)
Cov tshuaj lom neeg muaj pes tsawg leeg rau Z150 yog cov tswv cuab thiab txawv los ntawm cov chaw tsim khoom. Nws yog qhov qis - alloy steel ua tib zoo tsim los ua kom tiav lub zog los ntawm kev kho cua sov. Ib qho kev khwv tau ntau yuav zoo li no:
Rooj 2: Cov tshuaj lom neeg raug nplua (hnyav%)
| Lub ntsiab | Cov Khoom Nquag Yog | Lub hom phiaj |
|---|---|---|
| Carbon (c) | 0.25 - 0.35 % | Ua kom muaj zog zog thiab hardness. |
| Manganese (mn) | 0.60 - 1.20 % | Ua kom muaj zog zog thiab ua tsis tau. |
| Molybdenum (mo) | 0.40 - 0.80 % | Txhim kho cov khoom nyuaj thiab lub zog, tshwj xeeb tshaj yog thaum muaj kub. |
| Chromium (cr) | 0.80 - 1.50 % | Txhim kho cov neeg muaj zog, kev xeb, thiab oxidation tsis kam. |
| Npib tsib caug (ni) | 0.50 - 1.50 % | Nce kev nyuaj thiab tsis muaj zog, tshwj xeeb tshaj yog nyob rau hauv cov ntawv ntsa hnyav. |
| Vanadium (V) | 0.05 - 0.15 % | Ua kom tau cov qauv lis cov qauv thiab nce lub zog los ntawm kev ua kom nag lossis daus. |
| Lwm tus (S, P) | Tsawg dua los yog sib npaug rau 0.010% | Khaws cia tsawg los txhim kho kev nruj thiab txo qhov kev pheej hmoo ntawm kev tawg. |
4. Sab thiab kuaj cov qauv
Txawm hais tias yog cov qib tshem tawm, txhua Z150 tus yeeb nkab yuav ua raws li qhov seem thiab kev sim ntawm API 5CT cov qauv uas tau siv rau lub sijhawm.
Qhov loj me:Sab nraum txoj kab uas hla (OD), Phab Ntsa Thickness (WT), thiab ntev rau ib API 5ct.
Threading:Tuaj yeem muab nrog cov qauv API cov xov (piv txwv, LTC, STC) lossis, feem ntau rau qhov siab- ua tiav qib, nrogCov Kev Sib TxuasLos ntawm cov tuam ntxhab nyiam Vallourec, Tenaris, lossis tua tsiaj.
Kuaj:Yuav yauv tau xeem tag nrho suav nrog hydrostatic kev sim, kuaj cov seem, thiab tsis yog- kev sim siab (ndt). Cov kev ntsuam xyuas ntxiv xws li Charpy V - cov kev ntsuas cuam tshuam rau cov qauv.
Cov ntsiab lus thiab cov kev xaiv niaj hnub
Txij liZ150 tsis yog ib qib API nquag, engineers tsim cov dej num zoo yuav tsum tau siv cov kev ua tau zoo ib txwm siv:
High - Kev Ua Haujlwm Cov Qeb Prodrietary:Cov neeg tsim khoom muaj lawv tus kheej ultra- high- lub zog kawm tau yooj yim thiab zoo dua rau cov chaw ib puag ncig. Piv txwv li:
Vallourec:VM-150
Kaum-:Xiav ™ 125/130/140/150
Lwm tus:Tus tswv 140-150 Ksi qib
Q125:Qhov siab tshaj plaws - lub zog qib tam sim no tau teev nyob rau hauv API 5ct, uas tau pab raws li ntau ultra- Cov ntawv thov cov ntaub ntawv.
Rau txhua qhov haujlwm xav txog qib li z150, nws yog qhov tseem ceeb rauncaj qha sab laj nrog tus nqi them seTxhawm rau kom tau txais feem ntau up - rau -}} Hnub cov ntaub ntawv cov ntaub ntawv thiab kev txhawb nqa kev lag luam rau koj cov kev mob zoo.
