Casing yog ib feem tseem ceeb ntawm cov roj & roj qhov dej. Nws ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev ncaj ncees zoo thaum lub sijhawm ua tiav lub neej zoo, txij li qhov drilling, mus rau ntau lawm, txog thaum tso tseg. Zoo li tom qab tso tseg, raws li qee qhov casings deteriorate thiab pib xau hydrocarbon rau saum npoo.
Lub sijhawm txuas ntxiv no, qhov twg lub casing raug muab tso rau kev pabcuam, hais kom ua tiav kev xaiv cov casing. Cov txheej txheem no yuav siv sij hawm los xav txog qhov chaw nyob qhov twg lub casing tau muab tso rau hauv, thiab daim ntawv thov uas lub casing yuav siv rau.
Dab tsi peb saib thaum xaiv Casing?
Casing xaiv los tom qab tus txheej txheem Casing Design, uas yuav siv sij hawm mus rau hauv tus account zoo profile thiab tag nrho cov loads exerted rau lub casing thaum lub sij hawm tag nrho lub neej voj voog.
Muaj tsib yam casing peb saib thaum ua Casing Design:
- OD thiab ID
- Nyhav ib unit ntawm qhov ntev
- Joint Ntev
- Qib hlau
- Hom kev sib txuas
Thawj peb cov txheej txheem yog suav tias yog qhov loj me thiab feem ntau cuam tshuam los ntawm kev ua haujlwm (muaj, cov khoom tiav, lub rooj zaum qhov tob, qhov tho me me, kev cuam tshuam yav tom ntej ... thiab lwm yam).
Qhov thib ob qhov tseem ceeb yog qhov tseem ceeb tshaj rau kev ncaj ncees. Kab lus no yuav kov ntawm cov txheej txheem Steel Qib nkaus xwb.
Casing Steel Qib yog dab tsi?
Lub Casing Steel Qib yog ib qeb ntawm cov hlau uas nws muaj nws tus yam ntxwv thiab specifications.
- Casing Steel Qib sib txawv hauv peb yam:
- Steel alloy formulation thiab muaj pes tsawg leeg
- Manufacturing txheej txheem nyob rau hauv cov nqe lus ntawm kev siv tshav kub kho
- Mechanical zog xws li yam tsawg kawg nkaus yield zog
API Casing Steel Qib yog dab tsi?
Thaum muaj kaum ob ntawm Casing Steel Qib muaj nyob hauv khw, API tau teev cov hauv qab no raws li qib API:
- H-40
- J-55
- K-55
- M-65
- N-80 (N-80.1, N-80.Q)
- L-80 (N-80.1, L-80.9Cr, L-80.13Cr)
- C-90
- C-95
- T-95
- R-95
- C-110
- P-110
- Q-125
Lub Casing Steel Qib yog qhia los ntawm tsab ntawv thiab tus lej. Thaum Tus lej sawv cev rau qhov tsawg kawg nkaus lub zog tawm los, Tsab Ntawv tsis muaj qhov tseem ceeb thiab tau raug xaiv los ntawm arbitrarily.
Puas muaj lwm yam kev faib tawm rau Casing Steel Qib?
Yog lawm, cov qib casing saum toj no tau muab faib ua 4 pawg (lossis feem ntau hu ua Cov Qib Kev Pabcuam). Qhov no categorization yuav siv sij hawm rau hauv ob qho tib si:
tiv thaiv sulfide kev nyuaj siab tawg
ua hauj lwm siab
Tnws API Casing Steel Qib pawg yog:
- Pawg 1: H-40, J-55, K-55, N-80, R-95
- Pawg 2: M-65, L-80, C-90, C-95, T-95, C-110
- Pawg 3: P-110
- Pawg 4: Q-125
Tsis tas li ntawd, Muaj lwm txoj kev ywj pheej hu ua Product Specification Level (PSL). Qhov kev faib tawm no faib cov API Casing Steel Qib rau hauv peb PSLs raws li lawv daim ntawv thov:
- PSL-1: Common Application Casing (H-40, J-55, K-55, M-65, N-80, R{{6 }})
- PSL-2: Corrosion-Resistance Casing (L-80, C-90, T-95, C-110)
- PSL-3: Deep Well Casing (P-110, Q-125)
Txawm hais tias muaj qhov sib txawv ntawm cov qib casing Steel Qib, qhov chaw ua haujlwm ntawm lub casing (qab zib thiab qab zib, kev ntsuas siab, qhov kub thiab txias) tseem yog lub hauv paus rau kev xaiv cov txheej txheem casing. Yog li ntawd, kev txheeb xyuas qhov raug cov qib casing nyob rau theem tsim yog qhov tseem ceeb los xyuas kom meej qhov zoo ntawm nws lub neej.
Lub casing thiab tubing uas tsim los ntawm Vigor yog tsim thiab tsim nyob rau hauv nruj raws li API 5CT cov qauv, thiab Vigor's QC pab neeg yuav muab peb cov neeg muas zaub nrog ntau lawm npaj ua ntej thiab tawm tswv yim txog qhov project nce nyob rau hauv lub sij hawm, kom peb cov neeg muas zaub yuav paub lub cov xwm txheej ntawm cov khoom txhua lub sijhawm. Vigor ib txwm ua raws li lub tswv yim ntawm cov neeg siv khoom centricity, tau cog lus los muab cov neeg siv khoom nrog cov khoom zoo tshaj plaws thiab cov kev pabcuam, yog tias koj txaus siab rau Vigor lub drilling thiab ua tiav cov cuab yeej, thov tsis txhob yig tiv tauj nrog peb kom tau txais kev pabcuam zoo tshaj plaws thiab kev txhawb nqa kev tshaj lij tshaj plaws.
