Casing yog cov pob txha pob txha ntawm cov roj lossis roj qhov dej - nws kab cov borehole los ntawm qhov chaw mus rau lub hom phiaj qhov tob, cais cov chaw tsim khoom, thiab tuav tag nrho lub qhov dej tiv thaiv kev sib tsoo, tawg, thiab tsim cov dej tsiv teb tsaws rau lub qhov dej ua haujlwm. Tsis muaj kev txhim kho casing thaum nws tau cemented hauv qhov chaw, uas yog vim li cas qib thiab kev sib txuas xaiv tsim nyog tau txais kev saib xyuas ntau dua li lawv feem ntau tau txais ntawm PO theem.
Xaiv cov qib zoo tsis yog hais txog "Zoo dua yog qhov zoo dua"
Qhov yuam kev tshaj plaws uas peb pom hauv cov lus nug casing yog kho cov qib kev xaiv raws li tus ntaiv lub zog yooj yim - xav tias tus lej siab dua txhais tau tias muaj kev nyab xeeb dua, xaj qib siab tshaj koj tuaj yeem them taus. Cov logic ntawd tawg sai sai thaum cov kev pabcuam corrosive nkag mus rau hauv daim duab.
- J55/K55- yield zog 379-552 MPa, sib qhia tib yam chemistry, sib txawv ntawm lub zog tensile (517 MPa min rau J55, 655 MPa min rau K55). Tus nqi -zoo rau qhov dej ntiav, tsis muaj corrosive nrog lub siab nruab nrab.
- N80 Hom 1 thiab N80Q- ib kauj ruam nce hauv lub zog (tso tawm 552-758 MPa), haum rau qhov dej tob; N80Q nqa ntxiv quenched-thiab-tempered kev kho cua sov kom txhim kho toughness.
- L80 (L80-1, L80 9Cr, L80 13Cr)- hardness capped ntawm HRC 23, lub hom phiaj- ua rau H2S (kub) kev pabcuam. Qhov no yog sulfide-kev nyuaj siab- kev tswj kev tawg, tsis yog lub zog spec - L80 zoo xaj raws li N80 kom txuag tau tus nqi yog qhov corrosion tiag tiag -kev pheej hmoo tawg, tsis yog technicality.
- P110- yield 758-965 MPa, qhov muaj zog tshaj plaws ntawm cov dav dav- cov hom phiaj qib, siv rau hauv qhov tob tob, qhov siab siab qhov chaw tawg thiab tawg qhov ntsuas tswj tus qauv tsim.
Qhov kev txiav txim siab qib yuav tsum rov qab mus rau peb qhov tsis zoo: qhov tob (burst / collapse load), siab profile, thiab H2S / CO2 cov ntsiab lus - nyob rau hauv qhov kev txiav txim, tsis yog lwm txoj kev.
Kev sib txuas hom hloov tag nrho txoj hlua tus cwj pwm
STC (short round thread), LTC (ntev round thread), thiab BTC (buttress thread) tsis hloov pauv ntawm tus nqi ib leeg. STC muaj qhov sib koom ua haujlwm qis tshaj plaws thiab feem ntau txwv rau ntiav, qis - cov hlua siab. BTC muaj kev sib koom ua ke ntawm cov xov muaj zog thiab muaj zog sib koom ua ke ntau dua, ua rau nws yog qhov kev xaiv rau kev sib sib zog nqus los yog siab dua -load casing hlua. Qhov twg roj- nruj sealing los yog huab cua torque / nro yuav tsum tau - kab rov tav laterals, siab - lub kaum sab xis, los yog siab - siab gas - premium (proprietary) kev sib txuas tau teev tseg es tsis txhob API threads nkaus, ntawm tus nqi tsev siab dua.
Ib txoj hlua tsim nyob ib ncig ntawm BTC- ntsuas kev sib koom ua ke tab sis xaj nrog STC kev sib txuas los ntawm kev ua yuam kev yuav tsis ua rau lub zeb tshuaj xyuas - nws ua tsis tiav ntawm qhov chaw zoo, hauv qab thauj khoom sib txuas tsis tau ntsuas rau.
Manufacturing thiab Quality Control
Peb API 5CT casing yog tsim los ntawm tus qauv seamless txoj kev:
- Round billet cua sov
- Piercing (rotary piercing zeb ua rau lub plhaub hollow)
- Elongating thiab sizing rau phiaj OD / phab ntsa
- Kev kho cua sov (zoo li qub, lossis quench-thiab- kub rau Q&T qib zoo li N80Q, L80, P110)
- Ncaj
- Tag nrho -ntev ultrasonic thiab/los yog electromagnetic soj ntsuam (UT/EMI) rau longitudinal thiab transverse defects
- Hydrostatic kuaj ntawm txhua qhov sib koom ua ke
- Threading, coupling ua-up (lossis premium txuas machining), thiab API monogram cim
Txhua qhov cua sov yog chemistry- kuaj, txhua qhov sib koom ua ke yog ntsuas txhua qhov API 5CT's sampling zaus, thiab daim ntawv pov thawj zeb raug xa tawm rau qib PSL.
Qhov twg siv - thiab qhov twg hloov tsis yog lub tswv yim zoo
Cov hlua casing yog khiav hauv theem - tus neeg xyuas pib, nto, nruab nrab, thiab ntau lawm casing - nrog qib thiab phab ntsa tuab feem ntau nce nrog qhov tob. Ib txoj hlua ntiav nto tuaj yeem khiav J55; cov hlua ntau lawm nyob rau hauv qhov tob, qaub roj zoo tsis tuaj yeem. Peb niaj hnub pom cov neeg yuav khoom sim ua tus qauv ntawm ib qib thoob plaws ib qho kev pab cuam kom yooj yim rau kev yuav khoom - ua haujlwm tau rau saum npoo, muaj kev pheej hmoo rau txhua yam kov qhov qaub lossis siab - cheeb tsam siab.
Illustrative Case:Ib tus neeg yuav khoom qhov chaw rau qhov dej nkag rau hauv qhov chaw paub tab tau teev tseg N80 hla tag nrho txoj hlua, raws li qib siv ntawm cov qhov dej offset drilled ib xyoo caum dhau los. Daim ntawv teev cov khoom siv los ntawm lub qhov dej nyob ze pom tau tias H2S nce siab txij li cov qhov dej ua ntej tau drilled. Peb chij qhov tsis sib haum ua ntej xa khoom xa tuaj; tus neeg teb xov tooj hloov txoj hlua ntau lawm rau L80 9Cr, khaws N80 rau saum npoo thiab nruab nrab casing. Tus nqi ntawm cov khoom siv ntxiv yog ib feem me me ntawm tus nqi ntawm kev ua haujlwm ua los ntawm sulfide kev nyuaj siab tawg.
Vim Li Cas Koj Qhov Casing Los Ntawm Peb
Peb tsim thiab xa tawm API 5CT casing nyob rau hauv tag nrho cov ntawv pov thawj zeb, nrog rau cov cua sov- los ntawm - cov ntaub ntawv kub chemistry thiab kev sib koom ua ke - cov ntaub ntawv ntsuas cov tshuab thiab hydrostatic muaj nyob ntawm kev thov - tsis yog daim ntawv pov thawj cov ntsiab lus. Yog tias koj xa koj qhov kev pab cuam zoo rau peb (qhov tob, siab gradient, H2S / CO2 cov ntsiab lus, thiab kev nyiam kev sib txuas), peb yuav pom zoo rau qib thiab kev xaiv kev sib txuas sib npaug rau txhua txoj hlua casing, tsis yog ib qho -loj nqe lus. Xa koj cov specifications rau peb thiab peb yuav tig ib ncig ntawm cov ncauj lus kom ntxaws nrog lub sij hawm ua.
Cov lus nug nquag nug (FAQ)
Q: API 5CT casing puas tuaj yeem hloov nrog API 5L kab yeeb nkab yog qhov ntau thiab tsawg?
A: Tsis yog API 5L yog tsim los rau lub siab ntim hauv kev pabcuam kev sib kis; nws tsis nqa lub hauv paus tsim lub cev qhuav dej / tawg, sib txuas xov, los yog qaub- kev pabcuam qib tswj (xws li L80's hardness cap) uas casing tsim nyob ntawm.
Q: Puas yog L80 xav tau rau ib qho dej nrog H2S tam sim no, lossis tsuas yog muaj qhov siab?
A: NACE MR0175 / ISO 15156 teeb tsa cov theem pib raws li qhov siab ib nrab ntawm H2S, tsis yog muaj nyob xwb. Hauv qab qhov pib, N80 tseem tuaj yeem lees txais - tab sis qhov no yuav tsum tau lees paub tiv thaiv koj cov xwm txheej tshwj xeeb, tsis yog xav.
Q: Dab tsi yog qhov sib txawv ntawm LTC thiab BTC kev sib txuas?
A: LTC muaj cov xov txuas ntev dua li STC rau kev txhim kho kev sib koom ua ke, tab sis BTC lub taub hau xov profile muab siab dua tensile thiab compressive load muaj peev xwm dua li qhov kev xaiv - xov, uas yog vim li cas nws yog qhov kev xaiv ntau dua rau cov hlua sib sib zog nqus.
Q: Koj puas muab cov khoom sib txuas sib cais los ntawm cov pob qij txha?
A: Yog lawm, kev sib txuas cov khoom sib txuas thiab cov khoom tiav tiav yog muaj cais rau cov neeg ua haujlwm tswj hwm lawv tus kheej kev sib txuas ua- nce lossis kev tso cai zoo sib xws.
