Taw qhia
Cov roj casing yeeb nkab yog lub siab - lub zog steel yeeb nkab tsim los rau drilling thiab ua kom tiav cov roj thiab cov qhov dej. Nws txhawb nqa lub qhov dej, tiv thaiv kev sib tsoo, thiab cais cov dej hauv av, ua kom muaj kev nyab xeeb thiab muaj txiaj ntsig roj thiab roj rho tawm.

Nta
-
Kev cais kua dej
Sib cais cov roj, roj, thiab dej kom tsis txhob hla - paug.
-
High Pressure Resistance
Withstands downhole pressures mus txog 10,000 psi thiab kub txog 350℃F (177 degree).
-
Premium alloy steel (xws li J55, N80, P110 qib)
Nws ua raws li cov qauv thoob ntiaj teb xws li API 5CT (American Petroleum Institute) thiab ISO 11960, ua kom muaj kev ntseeg siab nyob rau hauv siab -siab, siab - kub (HPHT) downhole ib puag ncig.
- Cov cuab yeej tiv thaiv
Muab cov channel ruaj khov rau cov cuab yeej downhole, txo kev puas tsuaj los ntawm kev tsim cov khib nyiab.
Customization Options
-
Steel qib xaiv
(Basic) H40, J55, K55, N80, R95;(High -lub zog) C90, L80, M65, T95; (Anti-sulfur) P110; (Ultra-lub zog siab) Q125, xaiv raws li kev pabcuam.
-
Phab ntsa thickness yog raws li qhov yuav tsum tau muaj siab (2-100 hli, tuaj yeem kho tau).
-
PSL (Product Specification Level)
PSL1: Muaj feem xyuam rau qhov dej ntiav thiab tsis yog -ib puag ncig corrosive.
PSL2: Ua rau muaj kev cuam tshuam ntau zog, tsis yog - kuaj kev puas tsuaj, thiab kev taug qab siv tau rau qhov nruab nrab thiab qhov tob tob.
PSL3: nruj tswj ntawm hardenability, grain loj, thiab inclusions; siv rau siab -cov roj qhov dej siab thiab cov kab mob corrosive.
- Cov yeeb nkab ntev customization (6 m, 6.4 m, 12 m, lossis kev cai).
- Sab nraud txoj kab uas hla hloov kho rau tej casing designs.
FAQ
Q: Dab tsi yog cov kev siv ntawm cov roj casing kav?
A: Cov xwm txheej tseem ceeb suav nrog thaj chaw roj av / roj av, cov roj av / roj av drilling, qhov dej kub hauv qab, thiab txhim kho cov roj rov qab (EOR) cov haujlwm.
Q: Koj puas tuaj yeem muab kev qhia txog kev tsim khoom thiab xaiv cov qauv tsim nyog?
A: 1. Rau qhov sib sib zog nqus, siab - qhov dej siab, siv qib PSL2/3 nrog QT kev kho cua sov, tag nrho tsis yog- kuaj kev puas tsuaj, thiab BC trapezoidal threads kom zoo dua sealing thiab tiv thaiv - nplaum.
2. Rau corrosive ib puag ncig (CO₂/H₂S), xaiv 13Cr, 22Cr duplex, los yog npib tsib xee alloys thiab ua raws li NACE MR0175/ISO 15156 tswj hardness thiab microstructure.
Q: Dab tsi yog hom roj casing kav thiab lawv cov ntawv thov theem?
A: Cov kav dej roj tau muab faib ua cov kav dej saum npoo (0-1,000 m) los tiv thaiv cov dej hauv av ntiav thiab txhawb nqa cov casings tom ntej, nruab nrab casing (1,000-3,000 m) kom cais tawm siab - siab los yog corrosive txheej, thiab cov casing ntau lawm (3,000 m+) los coj cov roj thiab roj ntws siab tshaj plaws.
