Coiled tubing, tseem hu ua flexible tubing, yog ua los ntawm cov pa roj carbon tsawg steel tubing nrog kev yooj yim kom tau raws li cov kev cai ntawm cov yas deformation thiab toughness yuav tsum tau los ntawm downhole kev khiav hauj lwm.Feem ntau siv coiled tubing specifications yog: Phi 1/2 peb-quarters ntawm 3/8 25.4mm, φ31.75mm, φ38.1mm, φ44.45mm, φ50.8mm, φ60.325mm, φ66.675mm, φ73.025mm .55mm, φ88.9mm, thiab lwm yam., yield zog 55000Psi ~ 120000Psi.Coiled tubing, uas yog qhov txhab ntawm cov menyuam thiab tuaj yeem ua tau ntau txhiab meters hauv qhov ntev, tuaj yeem hloov cov pa threaded tubing rau kev ua haujlwm tsis tu ncua ntawm lub qhov nrog lub siab.Coiled tubing tau dav siv hauv kev drilling, txiav, ua tiav, kev ua haujlwm ua haujlwm, thiab ntau thiab ntau dua hauv kev tshawb nrhiav roj thiab roj.
Txawm hais tias peb lub teb chaws ntev dhau los pib siv coiled tubing thev naus laus zis hauv kev ua haujlwm hauv av, tab sis vim yog kev cuam tshuam ntawm ntau yam ua rau coiled tubing tshuab tsis tau txais ntau qhov kev loj hlob nrov hauv peb lub teb chaws, txoj kev xav thiab kev siv thev naus laus zis piv nrog cov tsim. lub teb chaws tseem muaj qee qhov sib txawv, uas ua rau muaj kev siv tiag tiag hauv cov txheej txheem ntawm coiled tubing kom ua tiav kev siv qhov kom zoo dua.Tsis tas li ntawd, feem ntau ntawm kev ua haujlwm hauv av hauv peb lub tebchaws muaj nyob rau hauv kev siv cov tshuab coiled tubing qhov muag tsis pom kev, tsis muaj cov ncauj lus kom ntxaws txog kev tsim ua ntej siv, xws li kev siv cov cuab yeej siv thiab kev siv tshuab thiab siv ntau yam, ua rau cov coiled tubing tshuab yog siv rau. underground ua hauj lwm qis adaptability, nquag siv technology nyob rau hauv cov khoom siv tsis tsim ib tug tag nrho cov teeb meem, qhov tseeb ntawm cov cuab yeej siv thoob ntiaj teb kev mob ua rau tej yam phem phem.
Cov txheeb ze kev laus ntawm coiled tubing khoom
Tam sim no, feem ntau ntawm cov khoom siv hauv tsev siv coiled tubing yog cov khoom siv txawv teb chaws, cov cuab yeej siv tau rov qab, qee qhov txawm mus txog lub sijhawm kawg.Txhaj taub hau, tshuab tshuab tiv thaiv, hydraulic system thiab tswj kev hnav cov khoom yog qhov nyuaj los hloov thiab tswj.Qhov tsim nyog tubing txoj kab uas hla yog me me, qee qhov tshwj xeeb downhole kev ua haujlwm tsis tau raws li qhov yuav tsum tau ua ntawm kev tsim kho.
Kev siv cov tshuab coiled tubing
Daim ntawv thov ntawm cov roj nqa roj rov qab
Cov roj nqa roj rov qab siv tshuab yog txhaj cov roj rau hauv lub qhov dej thiab siv qhov nthuav dav ntawm cov roj kom txo qhov ntom ntawm cov kua sib xyaw hauv lub qhov dej, kom cov roj hauv lub qhov dej tuaj yeem ntws tawm yooj yim dua.Daim ntawv thov ntawm coiled tubing thev naus laus zis tau txhim kho cov txiaj ntsig zoo ntawm cov roj av rov qab thiab qib roj rov qab thev naus laus zis.Hauv ntau qhov chaw, cov roj ammonia raug txhaj rau hauv qab ntawm lub qhov los ntawm coiled tubing (CT) thev naus laus zis los txhim kho cov roj thiab roj rov qab.
Tshiab ct ntsug Wells tau drilled
Tshiab coiled tubing Wells yog drilled siv ib tug composite rig nrog rau sab saum toj tsav uas yog drilled nyob rau hauv ib tug zoo xws li thaum pib ntawm drilling.Thaum lub laum mus txog qhov tob, nws hloov mus rau coiled tubing drilling, tom qab ntawd nws tuaj yeem khiav casing lossis ua kom tiav qhov qhib qhov dej.Undirected drilling nyiaj rau feem ntau ntawm cov tshiab ct Wells.
Qhov zoo ntawm ct drilling tshiab Wells yog kev nyab xeeb, ceev ceev drilling (tsis muaj dab tshos), kev thauj mus los yooj yim, hneev taw me me, siab automation thiab kev txuag hluav taws xob.Tam sim no, qhov ceev ntawm coiled tubing drilling txawv teb chaws yog ceev heev.Rau lub qhov dej CBM ntawm 700m txog 1000m, nws tsuas yog siv sijhawm 4 hnub los ntawm kev teeb tsa ntawm cov cuab yeej drilling mus rau kev tshem tawm tag nrho cov khoom siv drilling tom qab kev tsim kho.Canada tam sim no yog lub ntiaj teb cov chaw nquag tshaj plaws rau coiled tubing drilling.
Downhole kev khiav hauj lwm hauv cov roj teb muaj kev pheej hmoo, thiab kev siv cov tshuab coiled tubing yuav tsum muaj kev txawj ntse thiab cov cuab yeej siv nruj heev.Los ntawm ntau yam khoom siv siab heev los ua cov haujlwm downhole tuaj yeem txhim kho kev ua haujlwm zoo, rau kev nyab xeeb ntawm cov neeg ua haujlwm tsim kho kom muaj lub hauv paus rau kev lav.Txawm li cas los xij, txhawm rau txo qis lub sijhawm tsim kho, txo cov nqi thiab txhim kho cov txiaj ntsig, feem ntau ntawm Tuam Tshoj cov tuam txhab roj av txuas ntxiv tsim kho tshiab ntsig txog kev tsim kho tshuab thiab txheej txheem, tab sis tib lub sijhawm, tseem muaj qee qhov teeb meem hauv kev tsim khoom, yog li hauv cov txheej txheem. ntawm kev ua haujlwm hauv av, muaj cov khoom siv tsis txaus.Txhawm rau txhawb qhov nrov tshaj plaws ntawm coiled tubing tshuab, ua ntej koj xav tau cov cuab yeej siv dav dav raws li kev txhawb nqa, rau peb lub teb chaws kom ntxiv dag zog rau kev tsim cov cuab yeej muaj feem xyuam, nce peev peev, ua kom cov cuab yeej tsim nyog thiab cov chaw ua kom tau raws li qhov yuav tsum tau muaj ntawm txoj kev loj hlob. peb lub teb chaws, txhim kho kev ua tau zoo thiab siv cov cuab yeej siv, yog li muab lub hauv paus rau kev siv cov coiled tubing technology lav.
Kev loj hlob zeem muag ntawm coiled tubing
Txhawm rau ua ke cov kev ua haujlwm tsis zoo ntawm coiled tubing kev ua haujlwm, nyob rau theem kawg ntawm kev loj hlob ntawm cov roj av, coj qhov kev nce qib ntawm cov thev naus laus zis zoo tshaj plaws, txhawm rau txhim kho daim ntawv thov cov nyhuv ntawm coiled tubing, ua kom muaj peev xwm ntawm kev ua haujlwm coiled tubing, ua si lub coiled tubing kev ua haujlwm muaj peev xwm, lav qhov kev ua tiav ntawm kev ua haujlwm hauv av, pab ua kom nws zoo dua rau oilfield ntau lawm.
Txoj kev loj hlob zeem muag ntawm coiled tubing nyob rau hauv lub sij hawm tom qab yog soj ntsuam los txhim kho lub automation degree ntawm nto tswj cov cuab yeej ntawm coiled tubing, tas li optimize cov kev ntsuas ntawm coiled tubing ua hauj lwm, txhim kho qhov ceev ntawm underground ua hauj lwm thiab kev tsim kho, shorten lub sij hawm ntawm kev ua hauj lwm thiab kev tsim kho, thiab xyuas kom meej qhov ua tiav ntawm kev ua haujlwm hauv av thiab kev tsim kho.Kev tshawb fawb downhole cov cuab yeej, ua kom nws koom tes nrog coiled tubing tshuab ntsuas, txhim kho kev khiav hauj lwm thiab kev tsim kho theem ntawm kab rov tav Wells nyob rau tom qab theem ntawm oilfield kev loj hlob, coj qhov zoo tshaj plaws muaj peev xwm tshawb nrhiav thiab stimulation technology ntsuas, txhim kho lub reservoir tso zis, ua tau raws li qhov yuav tsum tau ntawm ntau lawm. oilfield kev loj hlob.
Kev txhim kho txuas ntxiv ntawm cov ntaub ntawv coiled tubing, daim ntawv thov cov ntaub ntawv tshiab thiab cov cuab yeej tshiab rau coiled tubing ua haujlwm tshuab, hloov txoj kab uas hla lossis hloov lub taper ntawm coiled tubing daim ntawv thov, los daws cov teeb meem nyuaj ntawm kev ua haujlwm tshwj xeeb zoo downhole.Kev yooj yim downhole kev ua haujlwm thiab kev tsim kho hauv qhov tob tob, txo qhov hnav ntawm coiled tubing thiab txuas ntxiv lub neej kev pab cuam ntawm coiled tubing.
