• Mbere - guhangayikishwa no kuvura umuyoboro wimbere kugirango umutekano

Umuyoboro w'imbere utangwa mbere yo - guhangayikishwa mbere yo gusudira bwa nyuma, kugirango kwaguka k'umuriro no kugabanuka mugihe cyo gusudira no gukora umurima bidatera guhangayika kwangiza. Ibi bifasha kugumya gusudira hamwe no gufatanya hamwe mumashanyarazi hejuru yubushyuhe bwinshi no gukonjesha.

Muguhuza iyi double - imiyoboro hamwe naimishwarara ikingira, irinda cyane, vacuum nini imbere - tube pre - guhangayika, Octal izinguye kugabanya kugabanya ubushyuhe kumuriba mugihe ukomeje kwitwara neza nkumugozi umenyerewe wa OCTG.

Ingingo yingenzi yubuhanga ni uko imikorere yubushyuhe itagenwa nibikoresho byonyine. Muri serivisi yo mu murima, gutakaza ubushyuhe byibasiwe cyane na annulus itajegajega, iherezo - gusudira ubudakemwa hamwe hamwe - kugenzura ubushuhe nyuma yubushyuhe bukabije. Niyo mpamvu pre - yashimangiye igituba gikingira cyane cyane muri serivisi ya parike ya cycle aho kuba muri serivisi - gusa.

Umuryango wibicuruzwa urashobora kumvikana neza binyuze muburyo butanu butaziguye - gukoresha icyerekezo: uburemere - kugarura ubushyuhe bwamavuta, gukumira imishwarara ya permafrost mumirima ya peteroli na gaze, iriba - amariba y’ibishashara, gushyushya amashanyarazi no kubyara amashanyarazi, hamwe n’iriba rishyushye -. Ibi bifasha kwerekana ko intera itagarukira gusa ku gutera inshinge wenyine; irashobora kandi gutoranywa ukurikije ubushyuhe - inshingano zo kubungabunga amazi ashyushye - amazi na serivisi ya geothermal.

Ashyushye - amariba

Kubushuhe - iterambere ryimpeshyi, agaciro ka tebuline cyangwa insinga ya insulasiyo ntabwo igabanya gusa gutakaza ubushyuhe, ahubwo ni no gukomeza ubushyuhe bwingirakamaro buboneka kuva mubwimbitse kugera hanze. Muri iyo mishinga, ubushyuhe bwo hejuru hamwe no kubungabunga ubushyuhe buhamye birashobora kuzamura agaciro k'ubucuruzi bw'iriba no kugabanya gutakaza ubushyuhe mugihe cyo kubyara.

Kugirango byoroherezwe kwerekana icyitegererezo, ingano yamakuru muri iki gice itunganijwe mumatsinda atandukanye. Imbonerahamwe yambere ikubiyemo ubunini busanzwe bwa vacuum insuline yumuryango ikoreshwa cyane mugutera inshinge, uburemere - umusaruro wamavuta hamwe nizindi serivisi zumuriro wa peteroli. Itsinda rya kabiri ryameza ryongeramo ubunini bwigiciro cya ting nubunini bwikigereranyo cyumuriro wumuriro. Imbonerahamwe ya gatatu yerekana imiyoboro isanzwe ya Octal ikoreshwa muburyo butaziguye mubushyuhe bwa geothermal - guhana no gushyuha - ubushyuhe bwimpeshyi {{6} service serivisi yo kubungabunga. Kugumisha iyi miryango ingano ituma isuzuma rya RFQ ryoroha kandi rifasha gutandukanya imirongo isanzwe yubushyuhe bwa peteroli hamwe nubushyuhe bwa geothermal - iboneza imiyoboro.

Octal vacuum insulation tubing iraboneka mumuryango ukurikira uhagarariye umuryango wa peteroli hamwe na parike - serivisi za serivisi.

Ku mishinga ifite isiganwa ryamagare ryisubiramo, umuryango wamamaye wigituba ingana hamwe na insulation - ibyiciro nabyo birahari. Indangagaciro zerekanwe neza munsi yimbonerahamwe isanzwe ya VIT nkibisobanuro byongeweho kubijyanye no gutoranya serivisi yumuriro -, cyane cyane aho abaguzi bakeneye kugereranya ingano, ibahasha ihuza, uburemere bwibikorwa hamwe nibikorwa byokwirinda murwego rumwe rwo gusuzuma.

Kubushuhe bwa geothermal, kubyara ingufu za geothermal hamwe nubushyuhe - amariba yisoko, umuryango wibicuruzwa urimo kandi umuryango wicyitegererezo wa Octal insulation. Kwerekana ubu buryo mumeza yigenga bituma geothermal nubushyuhe - byamazi byoroshye kubigereranya utabivanze nubunini bwa serivise -, kandi bigaha abaguzi aho batangirira ubushyuhe - uburyo bwo kubika no guhitamo icyitegererezo.

Kugirango byoroshye guhitamo injeniyeri, Octal izigamye itangwa muri byinshiamanota yubushyuhe:

• Icyiciro B.- λ ≈ 0.06–0.04 W / (m · dogere)
• Icyiciro C.- λ ≈ 0.04–0.02 W / (m · dogere)
• Icyiciro D.- λ ≈ 0.02–0.006 W / (m · impamyabumenyi)
• Icyiciro E.- λ ≈ 0.006–0.002 W / (m · dogere)

Urwego rwohejuru, niko gutakaza ubushyuhe kuri metero nibyizahepfo - umwobo mwizaKuri Imiterere Ubuso. Itsinda ryacu ryubwubatsi rirashobora kwerekana ubushyuhe bwo gutakaza nuburebure kuburyo ushobora kubona itandukaniro riri hagati yigituba gisanzwe, shingiropre - insing insingkandi hejuru - urwego Octal VIT ukurikije umwirondoro wawe wihariye.

Guhitamo bifatika, amanota yubushyuhe agomba gusomerwa hamwe ninshingano za serivisi. Muri parike - inshinge hamwe nuburemere - imishinga ya peteroli, ubushyuhe buke bwumuriro bivuze ubwiza bwamazi menshi mubwimbike bwikigega no kohereza ubushyuhe budakenewe muri annulus. Muri geothermal nubushyuhe - imishinga yimvura, ubushyuhe buke bwumuriro bivuze ubushyuhe bwo hejuru hamwe nubushyuhe bukoreshwa hejuru. Niyo mpamvu urwego rwimikorere rugomba guhuzwa ningufu zinganda zumushinga, ntizifatwa nkumubare wihariye.

Kubaguzi ba tubing insulée, ibibazo byingenzi ntabwo "ufite ingano zingana iki?", Ariko:

• Nangahe ubushyuhe bangahe nshobora kuzigama mu iriba ryanjye?
• Igishushanyo cyaba cyiza cyane - amazi, gutera inshinge cyangwa kumiterere yubutaka?
• Nshobora kubona k - agaciro nubushyuhe bwubushyuhe mbere yuko ntumiza?

Kugira ngo usubize ibyo, Octal ivuratubingnka sisitemu ya injeniyeri, ntabwo imwe - ubwoko - ihuye - ibicuruzwa byose.

Mubikorwa bifatika byo gushushanya, igituba gikingiwe cyatoranijwe kubikorwa bya serivisi, inshingano zubushyuhe nuburyo bwiza, ntabwo byakozwe na OD wenyine. Isubiramo risanzwe ritangirana nintego yo gukora: kubungabunga ubwiza bwamazi kugeza kubigega byimbitse mumariba ya CSS cyangwa SAGD, kugabanya ubushyuhe kumeneka kuri annulus mumasoko yimbitse -, kugabanya ubushyuhe bwagabanutse mumasoko y’ibishashara - bikunda kwibasirwa nubutaka bwakonje mukarere ka permafrost, cyangwa kubungabunga ubushyuhe bwakoreshwa mumazi yubushyuhe nubushyuhe -. Kuva aho, umugozi wa tubing usobanurwa nicyiciro cyo kubika, intego ya annulus vacuum, imiterere yo gushyigikira, guhuza ubushyuhe bwumuriro na serivisi - ubuzima busabwa mugihe cyamagare yubushyuhe bukabije.

Ubu buryo butanga abaguzi ishingiro ryokugereranya kurwego rwumushinga. Aho kugereranya igituba gusa nubunini nubwoko bwurudodo, guhitamo birashobora kugenzurwa no gutakaza ubushyuhe buteganijwe, hepfo - umwobo cyangwa ubushyuhe bwo gusohoka, ubushyuhe bwa annulus, neza - byimbitse kandi niba ubwubatsi bugenewe gutera inshinge, ubwinshi bwamazi - ubwishingizi bwamazi, kumurongo wubushyuhe cyangwa ubushyuhe bwa geothermal -. Iyo nayo ni logique yibice bikurikira: iboneza mbere, hanyuma ubushyuhe - ihererekanyabubasha muri annulus, hanyuma k - agaciro nubushyuhe bwo kwerekana, hanyuma amaherezo ya serivisi ubuzima nuburebure.

1. Iboneza ryerekanwe kumiterere yumurima
Aho kubaka inyubako imwe, Octal itanga ibishushanyo byinshi byubatswe byubatswe kumurongo umwe wimbere / hanze. Kubwimbitse - umusaruro wamazi twibanze kumurongo muremure - igihe gihamye hamwe na k - indangagaciro zo kugenzura ubushyuhe bwa annulus na hydrate risque; kubikorwa byamazi (CSS / SAGD) dushimangira ubushobozi bwo hejuru - ubushobozi bwubushyuhe no kurwanya amagare yumuriro; ku mariba yo ku nkombe no kurinda permafrost duhuza imbaraga zo gukumira hamwe nigiciro hamwe nuburemere bwimashini. Buri gikoresho gisobanurwa nicyiciro cyacyo cyo kubika, urwego rwa vacuum nuburyo bwo gushyigikira imbere, kuburyo ushobora guhuza umugozi wa VIT kumurima wawe aho guhuza umurima na tubing.

2. Kugenzura convection, imiyoboro n'imirase muri annulus
Ibishushanyo byacu bihuza uburyo butatu bwo kugabanya ihererekanyabubasha hagati yumuyoboro wimbere ninyuma:

• Igenzura- annulus yimuwe kurwego rwasobanuwe neza, cyangwa yuzuyemo gaze ya inert aho bibaye ngombwa, hasigaye rero amazi make asigaye yo gutwara ubushyuhe na convection. Abinjira muri annulus bafasha kugumana iyi miterere mubuzima bwiriba.
• Kugenzura imyitwarire- witonze ushyigikiwe neza kugumisha imiyoboro y'imbere ninyuma ihujwe mugihe hagabanijwe icyuma cyo guhuza icyuma, kugumana icyuho cyokwirinda no munsi yuburemere nubushyuhe.
• Kugenzura imirasire- ibyinshi - byiganjemo ibyerekezo hamwe na - ibyerekezo (bisa na sisitemu ya MLI) bigabanya ihererekanyabubasha ryinshi ryubushyuhe bwinshi.

Mugihe bikenewe, insulation yinyongera ikoreshwa hafi yaagace gahuriwehokugirango amasano adahinduka "ahantu hashyushye" mumurongo.

3. K - agaciro gashingiye kumikorere no kwerekana ubushyuhe
Imikorere yubushyuhe igaragazwa nk ak - agaciro(gutakaza ubushyuhe muri BTU / hr · ft · dogere F cyangwa W / m · dogere). Umuyoboro wa Octal uraboneka mubice byinshi k - agaciro kangana, uhereye kumurongo wimbitse - urwego rwamazi yagenewe ubushyuhe buke cyane, kugeza hejuru - k ariko amanota yubukungu menshi kuri serivisi - yubushyuhe buringaniye.

Kubikorwa byumushinga, itsinda ryacu ryubwubatsi rirashobora:

• kubara k - indangagaciro kubintu byatoranijwe byateganijwe,
• kwirukaubushyuhe - na - imyirondoro yimbitsekuri neza neza geometrie, na
• gereranya ibintu nka "bisanzwe tubing vs insulated tubing" cyangwa "hagati - urwego vs hejuru - urwego VIT".

Ibi biguha kureba neza hepfo - ubuziranenge bwamazi, ubushyuhe / ubushyuhe bwa annulus hamwe nubushyuhe bwo hejurumberewiyemeje gushushanya umurongo.

Imbonerahamwe yoroshye yo kugereranya hepfo yerekana uburyo ubushyuhe bwo hasi bwumuriro bujyanye nubushyuhe bwinshi - imbaraga zo gukuramo munsi yubushyuhe butandukanye - imiterere yubushyuhe.

Ubwubatsi bumwe nabwo bugera no muri geothermal kandi ishyushye - ikoreshwa ryamazi. Ibice bitatu byamashanyarazi - ibisobanuro byumuyoboro bisobanurwa nka Scheme A, B na C. Gahunda A igereranya iriba ridafite imiti ifatika, aho ubushyuhe bwinshi bwinjizwa kandi bukabura mubushyuhe - igice cyo kubika. Gahunda B ikoresha insulation hejuru yigice kugirango itezimbere ikoreshwa rya geothermal. Scheme C yubaka ubushyuhe bwuzuye bwo hasi - uburyo bwo kubungabunga kugirango imikoreshereze ya geothermal ikomeze gusunikwa cyane cyane mumariba yo hejuru -. Ibi bifite akamaro kuko bihuza guhitamo imiyoboro nubushyuhe bwa sisitemu - imikorere yo kubungabunga aho guhuza ubunini bwonyine.

Iyindi nzira yo gusaba ni ubushyuhe bwa coaxial - inzira yo guhanahana ukoresheje ikariso hamwe na centre - itunganya imiyoboro, aho umuyoboro wogukoresha ukoreshwa mukubungabunga ingufu za geothermal zingirakamaro kumugezi. Kubushyuhe bwa geothermal nimbaraga - imishinga yibisekuruza, guhitamo mubisanzwe biterwa nubushyuhe bwo hanze, igipimo cyizunguruka, kimwe - gukuramo ubushyuhe hamwe nubushyuhe bwumwaka, ntabwo ari OD gusa nubwoko bwurudodo.

Urubanza rwa PERT II ruhagarariwe hano hepfo kugirango rwerekane uburyo ubushyuhe bwo gusohoka hamwe nimbaraga imwe - isuzumabumenyi bisuzumwa muburyo bukoreshwa bwa geothermal.

Ubusanzwe imiterere ya geothermal ikubiyemo 273.05 × 11.43 mm ikarito ifite 178 × 135/194/154 mm ihuye nuburinganire bwumuyoboro wa metero zigera ku 4000-44500 hamwe n’ibisohoka bigera kuri 3750-4500, ikariso ya mm 244.5 × 10.03 hamwe na 140 × 100/154 mm ibyiciro bya mm 100 na m / 15/1004. amariba hamwe na kilowati 1000–1250, 177.8 × 9.19 mm hamwe na 114 × 81/127 mm ya gahunda yo gutondekanya ibyiciro bya m 2500-3000 na hafi 750-1000, hamwe na 139.7 × 7,72 mm hamwe na 89 × 62/99 mm byateganijwe kumariba agera kuri 2500–3000 na hafi 400-600.

Ibi bisobanuro byinyongera birakwiye ko byongerwaho kuko biha abaguzi inzira isobanutse yo kwemerwa kuva tube mbisi kugeza kurangiza hamwe.

Urebye amasoko, ikibazo cyubucuruzi ntabwo ari ukumenya niba ibicuruzwa bitangirana no gutakaza ubushyuhe buke, ahubwo ni ukumenya niba annulus ikomeza gufungwa, niba agace kegereye guma guma guma guma nyuma y’amagare y’umuriro ndetse n’uko ingingo zuzuye zishobora kurekurwa hifashishijwe insanganyamatsiko zisubirwamo hamwe n’ubushakashatsi bwakozwe. Niyo mpamvu igice cya QA kigomba kuguma gihujwe nigeragezwa ryubushyuhe, ubudahangarwa bwa vacuum, NDT, kugenzura ihuza hamwe ninyandiko hamwe aho kubifata nkibisabwa bitandukanye.

Ibisubizo byinshi byo gushakishatubingmubyukuri reba ibicuruzwa byo hejuru nkambere yo kubika PEX tubingku karere - ubushyuhe bwo gushyushya,kubumba umuringakuri HVAC,ubushyuhe bwakuweho kugabanuka tubinginsinga z'amashanyarazi, cyangwa ibintu byanditseho nkadekronikoreshwa mubikoresho byinganda. Ibicuruzwa bifite akamaro mumirima yabo, ariko nibyingenzintabwo yagenewe hasi - umwobo serivisi ya dogere 350-400, imitwaro myinshi yo kugwa cyangwa ibisabwa API 5CT.

Octal itanga ikindi cyiciro:ibyuma bya vacuum byashizwemo amavuta ya peteroli, gaze na geothermal. Ibicuruzwa byacu:

• ikoresha API 5CT - ibyuma byo mucyiciro aho gukoresha plastiki cyangwa umuringa.
• ni injeniyeri yo gutwara amavuta kandi ikabyara amazi munsi yumuvuduko mwinshi.
• ihuza hamwe na OCTG ikingira imirongo, ibikoresho byiza kandi hasi - ibikoresho byumwobo.
• kandi ikanyura murwego rumwe rwo kwipimisha OCTG nkibicuruzwa bitanga umusaruro, hejuru ya vacuum na test yumuriro.

Niba rero umushinga wawe ukeneyembere yo kubika PEX tubingcyangwakubumba umuringakumirongo yo hejuru, ibyo nibicuruzwa bitandukanye; mugihe ukeneye ibyuma bya insulasiyo bishobora kubaho mu iriba ubwaryo,Octal vacuum izing tubingni igisubizo gikwiye.

Octal itanga icyiciro gitandukanye: ibyuma bya vacuum byashizwemo umuyoboro woguhuza amavuta, gaze, geothermal nubushyuhe - amariba yamazi. Ibicuruzwa byubatswe mubyuma aho kuba plastiki cyangwa umuringa, byashizweho kugirango bitware amavuta cyangwa amazi ashyushye mubihe byiza, bihuza numugozi wa OCTG nibikoresho byo hasi, kandi unyura mubukanishi, ubushyuhe, vacuum no guhuza - kugenzura ubuziranenge.

Irindi tandukaniro ni uko uyu muryango wibicuruzwa utagomba kumvikana gusa nkamazi - yo gutera inshinge kumariba ya peteroli. Harimo kandi insulation - inzira yo gushyushya imiyoboro ya geothermal, kubyara ingufu za geothermal hamwe n amariba ashyushye -, aho agaciro gipimirwa nubushyuhe bwo hejuru, kubika neza ubushyuhe no gukomera - ubushyuhe bwiza -.
