Machubu opindika, omwe amadziwikanso kuti flexible chubing, amapangidwa ndi machubu achitsulo otsika a carbon alloy omwe amatha kusinthasintha bwino kuti akwaniritse zofunikira za kupunduka kwa pulasitiki ndi kulimba komwe kumafunikira pakugwirira ntchito pansi.Zomwe zimagwiritsidwa ntchito nthawi zambiri ndi: Phi 1/2 magawo atatu a 3/8 25.4mm, φ31.75mm, φ38.1mm, φ44.45mm, φ50.8mm, φ60.325mm, φ66.673mm, 2φ5mm 2φ8mm .55mm, φ88.9mm, etc., zokolola mphamvu 55000Psi ~ 120000Psi.Machubu ophimbidwa, omwe amalangidwa pa chodzigudubuza ndipo amatha kukhala mita zikwi zingapo m'litali, amatha kulowa m'malo mwa machubu okhazikika kuti azigwira ntchito mosalekeza ndikukankhira pansi.Machubu ophimbidwa akhala akugwiritsidwa ntchito kwambiri pobowola, kudula mitengo, kumaliza, kugwira ntchito mopitilira muyeso, ndi zina zambiri pakufufuza ndi chitukuko chamafuta ndi gasi.
Ngakhale dziko lathu layamba kale kugwiritsa ntchito umisiri wophimbidwa wamachubu pogwira ntchito mobisa, koma chifukwa cha chikoka cha zinthu zosiyanasiyana, ukadaulo wamachubu ophatikizidwa sunapeze chitukuko chodziwika bwino m'dziko lathu, chiphunzitso ndi ukadaulo poyerekeza ndi zomwe zidatukuka. maiko akadali kusiyana kwina, zomwe zimapangitsa kugwiritsa ntchito kwenikweni machubu ophimbidwa kuti agwiritse ntchito bwino ntchitoyo.Kuphatikiza apo, ntchito zambiri zapansi panthaka m'dziko lathu zimakhalapo pogwiritsa ntchito ukadaulo wamachubu ophimbidwa mwakhungu, palibe dongosolo latsatanetsatane la zomangamanga musanagwiritse ntchito, monga kugwiritsa ntchito zida ndi njira zaukadaulo komanso kugwiritsa ntchito mitundu yosiyanasiyana, kutsogoza ukadaulo wamachubu ophimbidwa umagwiritsidwa ntchito. ntchito yapansi panthaka yotsika kusinthika, ukadaulo wanthawi zonse pakugwiritsa ntchito zida sizipanga zovuta zonse, zenizeni za zida Zomwe zimagwiritsidwa ntchito padziko lonse lapansi zimayambitsa chikoka china.
Kukalamba pang'ono kwa zida zophimbidwa ndi machubu
Pakalipano, zida zambiri zapakhomo zomwe zimagwiritsidwa ntchito popanga machubu ndi zida zotumizidwa kunja, zida ndizobwerera m'mbuyo, zina zidafika nthawi yomaliza.Mutu wa jakisoni, chotchinga cha blowout, ma hydraulic system ndi makina owongolera ovala ndizovuta kusintha ndikuwongolera.Oyenera chubu m'mimba mwake osiyanasiyana ndi yaing'ono, ena apadera downhole ntchito sizikukwaniritsa zofunika pomanga.
Kugwiritsa ntchito matekinoloje a coiled tubing
Kugwiritsa ntchito mafuta okwera gasi
Ukadaulo wokweza mafuta a gasi ndikulowetsa mpweya m'chitsime ndikugwiritsa ntchito kukulitsa kwa gasi kuti muchepetse kuchulukana kwamadzi osakanikirana m'chitsime, kuti mafuta omwe ali pachitsime azituluka mosavuta.Kugwiritsiridwa ntchito kwa ukadaulo wamachubu ophimbidwa kwasintha kwambiri kuchuluka kwa kubwezeretsedwa kwamafuta osakhazikika komanso mulingo waukadaulo wobwezeretsa mafuta.M'madera ambiri, mpweya wa ammonia umalowetsedwa pansi pa dzenje kudzera muukadaulo wa coiled chubing (CT) kuti athandizire kuchira kwamafuta ndi gasi.
Zatsopano za ct vertical Wells zidabowoledwa
Machubu atsopano opindika Zitsime zimabowoleredwa pogwiritsa ntchito cholumikizira chophatikizika chokhala ndi choyendetsa chapamwamba chomwe chimabowoleredwa mwachizolowezi poyambira kubowola.Chobowolacho chikafika pakuzama kwina, chimasinthira ku kubowola kwa machubu opindika, kenako chimatha kuthamanga kapena kumaliza dzenje lotseguka.Kubowola mosadukiza kumapangitsa ambiri atsopano a ct Wells.
Ubwino wa ct pobowola Zitsime zatsopano ndi chitetezo, kubowola mwachangu (popanda kolala), mayendedwe osavuta, kaphazi kakang'ono, makina apamwamba komanso kupulumutsa ntchito.Pakali pano, liwiro anapiringa machubu pobowola kunja kwachangu kwambiri.Pachitsime cha CBM cha 700m kufika ku 1000m, zimangotenga masiku 4 kuchokera pamakonzedwe a zida zobowolera mpaka kuchotsa zida zonse zobowola pambuyo pomanga.Pakali pano Canada ndi dera lomwe likugwira ntchito kwambiri padziko lonse lapansi pobowola machubu.
Kugwira ntchito m'mabowo m'malo opangira mafuta ndikowopsa, ndipo kugwiritsa ntchito ukadaulo wamachubu ophimbidwa kumafuna ukadaulo komanso zofunikira pakugwiritsa ntchito zida.Kudzera zipangizo zosiyanasiyana zapamwamba kuchita ntchito downhole akhoza bwino patsogolo dzuwa la ntchito, chifukwa chitetezo cha ogwira ntchito yomanga kupereka maziko chitsimikizo.Komabe, pofuna kuchepetsa nthawi yomanga, kuchepetsa ndalama ndi kupindula phindu, ambiri mwa mabizinesi amafuta aku China akupitiliza kupanga luso lomanga ndi njira yolumikizirana, koma panthawi imodzimodziyo, pamakhala zovuta zina pakupangira zida, kotero kuti pakutha pogwira ntchito mobisa, pali kuchepa kwakukulu kwa zida.Kulimbikitsa kutchuka lonse la luso coiled tubing, choyamba muyenera mabuku dongosolo zida monga thandizo, kuti dziko lathu kulimbikitsa kupanga zida zogwirizana, kuonjezera ndalama likulu, kupanga zipangizo zoyenera ndi zipangizo kukwaniritsa chofunika chitukuko mu dziko lathu, kukonza magwiridwe antchito ndi kugwiritsa ntchito zida, motero kumapereka maziko pakukhazikitsa chitsimikizo chaukadaulo wamachubu.
Chiyembekezo cha chitukuko cha machubu ophimbidwa
Kuphatikizira zophophonya za machubu ophimbidwa, kumapeto kwa chitukuko cha malo opangira mafuta, kukwera kwaukadaulo wabwino kwambiri, kukonza magwiridwe antchito a machubu ophimbidwa, kumawonjezera mwayi wa opaleshoni yophimbidwa, kusewera luso lopangira machubu, zimatsimikizira kugwiritsa ntchito bwino ntchito zapansi panthaka, zimathandizira kuti zikhale bwino pakupanga mafuta.
Chiyembekezo cha chitukuko cha machubu ophimbidwa m'nthawi yamtsogolo chikuwunikiridwa kuti apititse patsogolo kuchuluka kwa zida zowongolera pamwamba pa machubu ophimbidwa, kukhathamiritsa nthawi zonse njira zamaukadaulo zopangira ma chubu ophimbidwa, kuwongolera kuthamanga kwa ntchito mobisa ndi zomangamanga, kufupikitsa nthawi yogwira ntchito ndi kumanga, ndikuwonetsetsa kuti ntchito yapansi panthaka ikutha bwino.Research downhole zida, kupanga izo kugwirizana ndi miyeso coiled tubing luso, kusintha ntchito ndi mlingo yomanga Wells yopingasa mu gawo lotsatira la chitukuko oilfield, kutenga njira yabwino kufufuza ndi kukondoweza luso luso, kusintha posungira linanena bungwe, kukwaniritsa zofunika kupanga kukula kwa mafuta.
Kupitiliza kuwongolera kwa zida zopindika zamachubu, kugwiritsa ntchito zida zatsopano ndi ukadaulo watsopano paukadaulo wopangira machubu ophimbidwa, kusintha m'mimba mwake kapena kusintha taper wa ntchito yophimbidwa yamachubu, kuthana ndi zovuta za ntchito yapadera yapabowo.Kugwira ntchito bwino kwa zibowo ndikumanga m'zitsime zakuya, kuchepetsa kutha kwa machubu ophimbidwa ndikukulitsa moyo wautumiki wa machubu ophimbidwa.
