Hauv kev lag luam roj thiab roj, tubing thiab casing qhov ntau thiab tsawg yog standardized los ntawm covAPI (American Petroleum Institute), tshwj xeeb hauv qabSpec 5CT.
Qhov loj ntawm cov kav dej no ib txwm raug xa mus los ntawm lawvSab nraud Diameter (OD). Txawm li cas los xij, vim tias qhov sib txawv ntawm phab ntsa thicknesses xav tau rau qhov sib txawv qhov tob thiab qhov siab, Sab hauv Diameter (ID) txawv.

Casing Sizes
Casingyog qhov loj - txoj kab uas hla cov yeeb nkab txo qis rau hauv lub qhov dej ntshiab thiab cemented nyob rau hauv qhov chaw. Nws tiv thaiv lub qhov dej los ntawm kev sib tsoo thiab tiv thaiv cov kua dej los ntawm cov dej hauv av.
Common Casing OD Loj:
Conductor Yeeb Nkab:16", 20", 24", lossis 30" (Cov hlua siv thawj zaug).
Nto Casing:10-¾", 13-⅜" (Tshwj xeeb thaj tsam dej ntshiab).
Intermediate Casing:7-⅝", 8-⅝", 9-⅝" (Siv rau hauv qhov tob tob kom hloov mus rau qhov chaw siab).
Production Casing:4-½", 5", 5-½", 7" (Txoj hlua zaum kawg uas khiav mus rau lub pas dej).
Qhov tseem ceeb Metric:Casing tau piav qhia los ntawmODthiabNyhav ib ko taw(piv txwv li, 5-½" 17 # casing).
Casing size specification
| Qeb | Common OD (Inches) | OD (mm) | Daim ntawv thov tseem ceeb |
| Tus coj | 16", 20", 24", 30" | 406 - 762 | Txoj hlua sab nraud; tiv thaiv topsoil collapse. |
| Nto Casing | 10-¾", 13-⅜" | 273 - 340 | Tiv thaiv thaj chaw dej tshiab; txhawb BOP pawg. |
| Intermediate Casing | 7-⅝", 8-⅝", 9-⅝" | 194 - 244 | Siv rau cov ntu complex (siab siab los yog poob zones). |
| Production Casing | 4-½", 5", 5-½", 7" | 114 - 178 | Txoj hlua zaum kawg tau teeb tsa los ntawm los yog siab dua lub reservoir. |
| Liner | Ntau yam | - | Ib txoj hlua uas tsis txuas mus rau saum npoo; hangs los ntawm yav dhau los casing. |
Tubing Sizes
Tubing yog cov yeeb nkab tso rau hauv lub casing. Nws yog lub conduit uas cov roj los yog roj yeej ntws mus rau saum npoo. Tsis zoo li casing, tubing yog tsim los rub thiab hloov yog tias nws corrodes los yog ntsaws.
Hom Tubing OD Loj:
Me me (Macaroni) Tubing:1.050", 1.315", 1.660" (Siv rau tshuaj txhaj tshuaj lossis qhov dej me me).
Standard Production Tubing:
2-⅜"(Ntau heev hauv cov laus lossis qis dua - ntim qhov dej).
2-⅞"(Cov qauv kev lag luam rau feem ntau onshore roj thiab roj qhov dej).
3-½"(Siv rau siab - ntim qhov dej).
Loj Bore Tubing:4", 4-½" (Siv nyob rau hauv high-tsim offshore los yog subsea qhov dej).
Tubing Sizes specification
| Qeb | Common OD (Inches) | OD (mm) | Daim ntawv thov tseem ceeb |
| Macaroni Tubing | 1.050", 1.315", 1.660" | 26.7 - 42.2 | Kev txhaj tshuaj tshuaj lossis slim- qhov ua haujlwm ua haujlwm. |
| Standard Tubing | 2-⅜" | 60.3 | Feem ntau nyob rau hauv qis dua - ntim lossis laus dua nyob rau hauv qhov dej. |
| Standard Tubing | 2-⅞"(Feem ntau) | 73.0 | Kev lag luam tus qauv rau feem ntau onshore roj / roj qhov dej. |
| Loj Bore Tubing | 3-½", 4", 4-½" | 88.9 - 114.3 | High -cov qhov dej tsim tawm, cov dej tawm sab nraud, lossis cov dej txhaj tshuaj. |
Length Classifications (Ranges)
API txhais peb "Ranges" rau qhov ntev ntawm txhua tus neeg sib koom ntawm cov yeeb nkab:
| Ntau yam | Ntev ntev (ft / m) | Tubing Length (ft / m) | Lus hais |
| Ntau yam 1 (R1) | 16 - 25 ft ({2}}m) | 20 - 24 ft ({2}}m) | Tsis tshua siv. |
| Ntau yam 2 (R2) | 25 - 34 ft ({2}}m) | 28-32 ft ({2}}m) | Feem ntau cov qauv kev lag luam. |
| Ntau yam 3 (R3) | > 34 ft (> 10.4m) | 38-42 ft ({2}}m) | Siv rau qhov dej tob kom txo tau cov kev sib txuas. |

FAQ
Qhov ntev ntawm lub casing yog dab tsi?
Roj / Gas Qhov Casings: Have standardized API length ranges (R-1: 4.88-7.62m, R-2: 7.62-10.36m, R-3: >10.36m), feem ntau tsim los ntawm 6-13m.
Flexible Waterproof Casings:Length yog kev cai- xam ib qho kev teeb tsa raws li Phab Ntsa Thickness + Extension Length (feem ntau 40-100mm tag nrho).
Qhov ntev ntawm 2 tubing yog dab tsi?
Range 2 tubing muaj qhov ntev ntawm tus qauv25 rau 34 ft. Qhov ntev tshwj xeeb no yog tsim los ua kom zoo dua kev tuav, kev thauj mus los zoo, thiab kev siv qhov chaw ntawm qhov drilling rigs thiab thauj tsheb hauv kev lag luam xws li roj thiab roj.
