API tubing specifications muaj ob peb nqe lus uas xaiv tau rau tus neeg yuav khoom thiab lwm cov kev cai uas yog los ntawm kev pom zoo ntawm tus neeg yuav khoom thiab lub khw. Qee qhov kev cai ntxiv no tseem ceeb heev rau ib daim ntawv thov; Yog li, yuav tsum paub siv cov lus API / ISO tubing specifications.


Tus tub luam yuav tsum paub txog API cov kev cai thiab kev sim cov txheej txheem. Tag nrho cov raj yuav tsum ua raws li API yam tsawg. Hauv cov qhov dej nyab tseem ceeb, tus neeg yuav khoom yuav xav tau txais thiab rov qab soj ntsuam cov khoom lag luam. Kev siv rau hauv cov kwj hoom (cov dej hauv H2S ntau dua 0.05 psi ib nrab), qhov kev pabcuam qaub qis yuav tsum tau muab coj los xyuas dua.


API tau tsim tshwj xeeb rau peb qhov sib txawv rau kev siv ua tub luam cov pob zeb txuas:

Sab nraub qaum taub thiab kev sib tsoo

Tsis tub luam thiab tub lag luam

Integral-joint tubing


API Spec. 5CT muaj xws li ib qho piv txwv ntawm API tubing sib txuas. Tag nrho peb cov kev sib txuas tau tapered thiab hloov cov ntawv xov nrog 8 los sis 10 threads / in., Nyob ntawm qhov loj me. Thaum casing yog siv ua tubing, ntev-thread coupling / luv-xov coupling thiab khaus-thread coupling sib txuas tau teev.


Qhov API sab nraud-upset-xaus (EUE) tubing kev txuas siv dav vim tias nws yog ib qho zoo, muaj kev sib txuas ua haujlwm nyob rau hauv feem ntau qhov dej. Cov kev sib koom tes hauv EUE tau tsim muaj kev sib koom ua ke hauv nro thiab siab zog ntau dua li ntawm cov yeeb nkab thiab, yog li ntawd, nws yog ib qho kev sib txuas sib txuas 100%. Kev txhim kho lub cev thiab kev sib khi, kev sib koom tes yuav tsum muaj kev sib txuas lus zoo raws li tau teev tseg hauv API RP 5A3.To txhim kho qhov kev sib tw ntawm API EUE hauv qhov kev pab cuam, txuas (saib API Spec 5CT SR 13). Yuav kom muaj ntau clearance, API tshwj xeeb clearance EUE couplings muaj. API EUE pob yas qis tuaj hauv OD ntau thiab tsawg ntawm 1.050 rau 4.500 nyob rau hauv.


API tsis-upset (NUE) tubing yog siv tsawg dua EUE tubing. Tus nqi ntawm NUE tsuas yog me ntsis tsawg dua EUE, thiab sib koom ua ke muaj zog tsawg dua. Lub coupling txoj kab uas sib txuas ntawm NUE tsawg tshaj li EUE, uas muaj qee qhov kev zoo dua yog thaum muaj kev txwv tsis meej. API NUE pob qij txha muaj nyob hauv qhov ntau thiab tsawg ntawm 1.050 rau 4.500 nyob rau hauv.


API integral-joint tubing muaj nyob hauv OD qhov loj me ntawm 1.315 txog 2.063 hauv API qhov txuas-sib txuas tub yees muaj 10-thooj ib daim ntawv nrog lub zog sib npaug uas tsawg tshaj li ntawm lub cev tsawg tshaj plaws, uas txwv tsis pub nws siv. Qhov OD cov raj ntawm cov leeg sib txuas ua ke yuav siv nws cov hlua khi loj los yog hauv cov qhov dej tawm thaum tso tawm los yog tso cov hlua. Cov couplings yuav tsum ua kom tiav txhua yam tsawg kawg nkaus uas tau teev tseg hauv API Spec. 5CT.API Spec. 5B3 thiab API RP 5B14 npog threading, gauging, thiab xov txheeb xyuas.


Muaj ntau cov khoom sib txuas (non-API) muaj. Cov pob qij txha no muaj txiaj ntsim thaum siv ntau dua los yog ntau tshaj qhov uas yuav tsum tau tshaj qhov uas tau muab los ntawm cov qib API. Cov pob txha tshwj xeeb no tau txais lawv cov khoom zoo dua los ntawm cov hauv qab no:

Cim xov profile

Lub nqus xub pwg

Hlau-rau-hlau ntsaws ruaj ruaj

Muab lub nplhaib

Sab hauv

Sab nraud

Cov pob txha pob txha

lwm yam zoo li


Ua ntej yuav los yog siv cov kev sib txuas ntawm kev sib txuas rau hauv qhov tseem ceeb, qhov kev pom zoo ntawm kev sib txuas lus rau ib daim ntawv thov yuav tsum raug txheeb xyuas los ntawm kev ntsuam xyuas kev pab cuam keeb kwm lossis kev sib txuas kev sib raug zoo xws li ISO 13679 rau cov txheej txheem ntawm kev siv Coiled tubing.


API cov qauv txheej txheem

Cov txheej txheem nram no siv rau kev siv API tubing qib.

H40-Txawm tias qib API, H40 feem ntau tsis siv nyob rau hauv tub qhua coob vim hais tias cov qoob loo qis dua kuj tsawg thiab tus nqi txuag tau J55 tsawg heev. Cov neeg muag khoom tsis tuaj yeem npaj cov ntawv no.


J55-Ib feem ntau siv qib rau feem ntau qhov dej thaum nws muaj cov qauv tsim. Qee cov neeg tsav tsheb tau pom zoo tias nws yog qhov ntev los ntawm cev los yog ua kom qis thaum muaj kev kub ntxhov thaum siv cov roj carbon dioxide los yog kev pabcuam zaubmov (qhov teebmeem ntawm qhov teebmeem hluavtaws); Txawm li cas los xij, xws li cov kev kho mob kub yog nce nqi. J55 yog qib "standard" rau tubing hauv feem ntau ntiav (<9,000 ft)="" thiab="" low-pressure=""><4,000 psi)="" qhov="" dej="" hauv="">


C75-Tsis tau muaj qib API ntau thiab feem ntau tsis muaj. Nws tau tsim los ua cov khoom siv zog ntau dua rau kev pabcuam zaubmov tabsis raug hloov los ntawm L80 tubing.


N80-Ib qib muaj hnub nyoog nrog cov tshuaj uas yuav tsum tau qhib. Nws yog susceptible rau H2S-vim SSC (acronym). Nws yog tau rau cov roj qab zib thiab cov roj hauv qhov dej thaum nws muaj cov qauv tsim. Txoj kev kho kom sov thiab kev kho kom sov yog qhov kev xav tau. Qeb N80 feem ntau yog pheej yig dua L80 qib.


L80-A txwv yield-tubing qib uas muaj nyob hauv Hom 1, 9 Cr, los sis 13 Cr. Hom 1 tsis tshua kim tshaj 9 Cr thiab 13 Cr tab sis ntau dua rau qhov hnyav-qhov txhuam. L80 Hom 1 siv feem ntau hauv cov roj thiab cov roj teb vim muaj zog dua J55. L80 txaus siab rau SSC cov kab mob hauv txhua qhov kev mob, tiam sis tej zaum yuav ua rau qhov hnyav-qhov corrosion. Txawm tias yav dhau los rau yav dhau los rau CO2- thiab me me H2S-contaminated wells, Hom 9 Cr ntau tau hloov los ntawm Hom 13 Cr. L80 13 Cr tubing tau txais koob nrov vim tias nws muaj CO2 uas zoo tshaj-qhov hnyav-qhov corrosion tsis ua haujlwm; Txawm li cas los, nws yog kim dua. Hom 13 Cr tej zaum yuav tsis haum rau hauv kev pabcuam zaub mov. Feem ntau, H2S ib nrab siab yuav tsum tsawg dua 1.5 psi rau kev siv lub L80 yam 13 Cr. Tus neeg siv yuav tsum sab laj National Assn. ntawm Corrosion Engineers (NACE) MR-01-75.


C90-Qib dua tshiab qib API nrog ob hom tshuaj sib txawv: Hom 1 thiab Hom 2. Tsuas Hom 1 raug nquahu kom siv cov kev pabcuam zaubmov. Feem ntau, qib no yuav tsum raug tshwj xeeb kom raug; nws siv tau feem ntau supplanted by T95.


T95-High-strength tubular qib uas muaj cov yeeb tshuaj sib txawv: Hom 1 thiab Hom 2. Tsuas Hom 1 yog kev pom zoo rau kev pabcuam zaubmov. T95 yog SSC resistant tab sis tsis hnyav-poob resistant.


P110-Cov laus P105 tubing qib, uas tau tso cai rau kev kho kom sov thiab ua kom sov, raug txiav, thiab casing P110 qib, uas yog kev txwv rau kev kho cua sov cua sov, thiab kev kho mob. Qhov kev ua kom muaj zog no feem ntau yog siv sib sib zog nqus cov roj qab zib thiab cov roj hauv qhov dej kom zoo. Cov qhab-nees no tseem ceeb rau SSC cov kev ua txhaum tshwj tsis yog tias qhov kub muaj siab (> 175 ° F). P110 qib qis dua me ntsis tshaj L80 Hom 1, tiam sis feem ntau tsis tshua kim tshaj C90 thiab T95 API txwv-yield qib.


Q125-Txawm hais tias tsis muaj cov qhab-nees API siab, cov neeg siv tau hais kom Q125 API tubing. Ntaus 1 Chemistry yog qhov zoo.


Tubing ntau yam (ntev) thiab me me ua haujlwm

API lees paub ob lub qhov ntev ntev: Ntau yam 1 ntawm 20 mus rau 24 ft thiab Range 2 ntawm 28 mus rau 32 ft. Khwv Siv 2 feem ntau yog siv. Cov pob zeb qej txha (cov pob qij txha ntxiv) muaj nyob rau hauv 2-, 3-, 4-, 6-, 8-, 10-, thiab 12-ft ntev nrog lub siab ntev ntawm ± 3 nyob rau hauv. Ib qho tiav ntawm tubing menyuam nrog tib kev txuas raws li txoj hlua txoj kab yog feem ntau yog muag rau txhua qhov dej.
