1. Cov khoom lag luam
API J55 yog cov pa roj carbon hlau casing hauv qabAPI spec 5ctTxheem, feem ntau siv hauv cov roj thiab roj drilling. Cov qauv tseem ceeb muaj:
| Chaw ua uas tsis tau haus | Tus nqi / lus piav qhia |
|---|---|
| Khoom Siv Khoom | J55 (Cov Hlau Hlau) |
| Paib lub zog | Ntau dua los yog sib npaug rau 379 MPa (55 ksi) |
| Lub zog tensile | Ntau dua los yog sib npaug rau 517 mpa (75 ksi) |
| Tshuaj Muaj Tshuaj | C Tsawg dua lossis sib luag rau 0.45%, mn tsawg dua los yog sib npaug nrog 1.20%, p tsawg dua lossis sib npaug lossis sib npaug nrog 0.045% |
| Txheej hauv lub taub | 139.7-244.5 hli (5.5-9.6 ntiv) |
| Phab Ntsa Thickness | 7.72-11.05 hli (0.3-0.43 nti) |
| Qho ntev | R-1 (4.88–7.62 m), R-2 (7.62–10.36 m), R-3 (>10.36 m) |
| Xov Hom | BTC (Luv Luv Xov), LTC (xov ntev) |
| Tus qauv | API spec 5ct, SY / T6194-96 (Suav teb) |
2. Cov ntawv thov
Roj & Roj Zoo: Txhawb kev ua haujlwm zoo thaum drilling thiab ntau lawm
Geothermal wells: Siv nyob rau hauv high - qhov projical geothermal
Dej Wells: Tiv thaiv kev vau rau hauv hydrogeological kev tshawb nrhiav
3. Qhov Zoo
Siab Zog: Withstands siab siab thiab lub zog muaj kev ntxhov siab hauv cov dej tob
Corrosion Kuj: Tsim nyog rau tsis - {{{1} {}} Cov qhab nia tsis txaus siab zoo li L80 yog nyiam rau cov mob corrosive)
Nqi -}}}}: Tus nqi qis dua piv rau qhov siab - bex steels (piv txwv li, p110)
Qauv: Ua raws li cov qauv API hauv ntiaj teb, ua kom muaj kev cuam tshuam sib txuas lus.
4. Kev sib piv nrog lwm qib
| Teem nqi | Paib muaj zog (ksi) | Raug siv cov ntaub ntawv |
|---|---|---|
| J55 | 55 | Ntiav mus rau nruab nrab - qhov tob tob |
| N80 | 80 | High - h siab zoo |
| P110 | 110 | Ultra -} Cov Dej Duaj |
Rau cov ncauj lus kom ntxaws kev sim (piv txwv li, flattening, hydrostatic siab), xa mus rau API spec 5ct.
