BOP yog siv los kaw lub qhov dej thaum lub sijhawm kuaj roj, kho kom zoo, thiab ua tiav kev ua haujlwm kom tsis txhob muaj kev sib tsoo. Nws muab tag nrho cov sealing thiab semi-sealing functions rau hauv ib qho, thiab muaj cov yam ntxwv ntawm cov qauv yooj yim, kev ua haujlwm yooj yim, thiab muaj zog ua haujlwm siab. Nws yog feem ntau siv kev ruaj ntseg sealing wellhead li nyob rau hauv cov roj teb los tiv thaiv blowouts. Muaj ob lub ntsiab ntawm BOP:IB annularthiabram BOP. Thaum siv BOP ntawm qhov chaw, ntau hom BOPs feem ntau ua ke raws li kev xav tau. Feem ntau, sab sauv yog annular BOP, qhov nruab nrab yog tag nrho ram BOP thiab shear ram BOP, qhov qis dua yog ib nrab ram BOP, thiab lwm yam. Muaj ntau qhov sib txawv raws li qhov chaw nyob.
Kev xaiv ntawm BOP Assembly
Cov yam tseem ceeb uas yuav tsum tau xav txog hauv kev xaiv hydraulic BOP kev sib xyaw ua ke yog: hom zoo, tsim siab, casing loj, tsim kua hom, cov neeg ua haujlwm cov txheej txheem, cov txheej txheem thev naus laus zis, kev nyab xeeb, kev nyab xeeb, tsheb thauj mus los, cov khoom siv, thiab kev tiv thaiv ib puag ncig. Hauv luv luv, nws yuav tsum muaj peev xwm ua tiav qhov sib npaug ntawm qhov drilling siab, xyuas kom muaj kev ruaj ntseg drilling, thiab txuag nqi drilling.
1)Xaiv Cov Qib Siab
Kev ua haujlwm siab ntawm hydraulic BOP sib dhos yog nyob ntawm lub siab tsis kam ntawm lub casing, lub siab tawg ntawm qhov qhib qhov tsim ntawm cov khau casing thiab qhov xav tau siab tshaj plaws hauv lub taub hau. Tab sis nws tsuas yog txiav txim siab los ntawm qhov siab tshaj plaws lub taub hau siab uas BOP lub rooj sib txoos yuav tsum tuaj yeem tiv taus. Muaj tsib qib BOP siab:14MPa, 21MPa,35MPa,70MPa,105MPa, thiab140MPa.
2)Xaiv Txoj Kab
Txoj kab uas hla ntawm BOP lub rooj sib txoos nyob ntawm qhov loj me hauv qhov tsim qauv ntawm lub qhov dej, uas yog, nws yuav tsum yog me ntsis loj dua li cov kab uas hla ntawm cov kab txuas txuas. Muaj cuaj hom BOP diameters:180mm,230mm,280mm,346mm,426mm,476 ibmm,528 ibmm,540mm ,ua680mm. Ntawm lawv,230mm,280mm,346mm ,ua540mm feem ntau siv rau ntawm qhov chaw.
3)Kev xaiv ntawm BOP Assembly
Kev xaiv ntawm kev sib xyaw ua ke yog feem ntau raws li kev tsim siab, kev xav tau ntawm cov txheej txheem drilling, cov cuab yeej drilling thiab cov khoom siv sib txuam.
BOP yog cov cuab yeej tseem ceeb tshaj plaws los xyuas kom muaj kev ruaj ntseg zoo. Raws li qhov sib sib zog nqus thiab ultra-ntxhais roj thiab roj qhov kev tshawb nrhiav thiab kev loj hlob tau dhau los ua qhov kev sib ntaus sib tua tseem ceeb rau cov roj thiab roj cia thiab kev tsim khoom nyob rau xyoo tas los no, kev tsim thiab tsim cov khoom tiv thaiv blowout kuj tau tsim rau siab dua thiab txoj kab uas hla loj dua. PWCE yeej ib txwm ua raws li cov ntsiab lus tseem ceeb ntawm kev nruj, kev tshaj lij thiab kev ntseeg siab, thiab tau cog lus los tsim ntau yam kev tiv thaiv zoo tshaj plaws. Thov hu rau peb kom paub ntau ntxiv txog cov khoom siv tshuaj tiv thaiv blowout.
Yog tias koj muaj lus nug lossis xav paub ntxiv, thov hu rau peb pab pawg muag khoom.
