Umupakira uhoraho hamwe nuwapakira

Umupakira uhoraho

Imiterere yashyizwe mubikorwa bihoraho ikurwa mumariba yo gusya. Izi nubwubatsi bworoshye kandi zitanga ubushyuhe bwo hejuru hamwe nigipimo cyimikorere. Gitoya ya diameter yo hanze yibice bihoraho ituma urwego rwo hejuru rwiruka imbere yumurongo wumugozi. Ubwubatsi bwuzuye bubemerera kuganira binyuze mubice bigufi no gutandukana biboneka kumariba. Ingano yazo imbere ya diametre ituma bikoreshwa mugukoresha imirongo ya tubing ya diameter yiyongereye no muri monobore yuzuye.

Zirakoreshwa kandi zishyirwaho hakoreshejwe insinga z'amashanyarazi, imiyoboro ya dring, cyangwa tubing. Bimaze gushyirwaho, ibintu birwanya icyerekezo kiva mubyerekezo byombi. Igenamiterere rya Wireline ryohereza umuyagankuba kugirango ushireho paki ukoresheje iturika ryumuriro uturika. Noneho sitidiyo yo gusohora itandukanya inteko nuwabipakira. Ibintu bihoraho nibyiza kumariba afite umuvuduko mwinshi cyangwa imitwaro itandukanye.

Gusubirana

Ibipakirwa bishobora gukururwa birimo byombi ubushyuhe buke / ubushyuhe buke (LP / LT) hamwe nuburyo bugoye bwo hejuru / ubushyuhe bwo hejuru (HP / HT). Ibicuruzwa bihenze kuruta ibyubaka bihoraho bitanga imikorere igereranywa bitewe nuburyo bugoye bwo gukora iyo ukoresheje ibikoresho bigezweho. Nyamara, ibintu nko koroshya gupakira ibicuruzwa neza no kongera gukoreshwa bifasha kuzimya igipimo cyibiciro.

Ibicuruzwa byongeye kugabanywa muburyo butandukanye, harimo:

Gushiraho uburyo: Gushiraho bikorwa binyuze muri tubing traffic yuburyo bumwe. Ibi birimo kuzunguruka cyangwa hejuru / kumanuka. Ikigeretse kuri ibyo, umutwaro ugira uruhare mugushiraho ibice nkuburemere bwigitutu bushobora kwikuramo cyangwa kwagura ikintu gifunga. Gukurura kumurongo urekura ibintu. Ibi bikunze kugaragara cyane, amariba agororotse afite umuvuduko muke.

Guhagarika umutima: Abapakira ibintu by'iri shuri bashyirwaho binyuze mu gukurura impagarara zashyizwe kuri tubing. Ubunebwe bukora kurekura ikintu. Bakora neza mumariba maremare arimo igitutu giciriritse.

Guhinduranya-gushiraho: Ibi bifashisha kuzunguruka kuri tubing kugirango ushireho imashini no gufunga mubice.

Hydraulic-set: Iki cyiciro gikora binyuze kumuvuduko wamazi utwara cone mumwanya winyuma. Nyuma yo gushiraho, haba gufunga imashini cyangwa igitutu cyafashwe bikomeza guhagarara. Gufata tubing itwara imikorere yo kurekura.

Inflatable: Bizwi kandi nkibintu byabyimba, ibyo bice bishingiye kumuvuduko wamazi kugirango uhindure imiyoboro ya silindrike kugirango uyishireho. Baboneka mugupima umwobo mugihe cyo gucukura amariba yubushakashatsi no kwishingira sima mugutanga amariba. Birakwiriye kandi ku mariba aho abapakira bakeneye kunyura mu mbogamizi mbere yo gushyira kuri diameter nini cyane muri casings cyangwa mu mwobo.

Reba birambuye birambuye kumahitamo akunzwe akurikira:

Ibishobora gukururwa bipakurura ibintu bishyigikira uburyo bwimbitse cyangwa buke bwo gukora cyangwa gutera inshinge. Ibi bifite urutonde rwinyandiko zidafite icyerekezo zifata gusa mugihe ibintu bifite umutwaro uremereye kuri tubing. Urwego tubing tension itera imbaraga ibintu. Iki cyiciro cyashyizweho muburyo bwa tekinike kandi kirekurwa hamwe no kuzunguruka. Ubwinshi bwikitegererezo buza hamwe byihutirwa-kurekura mugihe ibyibanze byo kurekura byananiranye.

Abapakira impagarara zirakoreshwa mubihe aho igitutu kiri munsi yigihe cyose kirenze igitutu cya annulus giherereye kubikoresho. Uyu muvuduko wo hejuru uhatira ibintu mukunyerera kugirango ukomeze impagarara.

Ibikoresho bisubirwamo bikuramo ibintu hamwe nibisukari byamazi nibyiza kubitoro bito n'ibiciriritse bya peteroli hamwe na gaze yo gucukura gaze mubushyuhe bwo hagati. Guhuza imashini bituma ibice bidashyirwaho. Mugihe ikorera mu mwobo, kuzunguruka tubing ikora element. Kurura ibibari biri kukintu ubifate mumwanya kandi bitange imbaraga zikenewe kugirango ubishyireho. Iyo interlock irekuwe, kumanura umugozi wa tubing byemerera gufunga kashe ya bypass no gushiraho impapuro. Gukoresha imbaraga zidacogora zikora kashe muguha ingufu ibicuruzwa. Isohora ryakozwe gusa mugukurura umugozi.

Ihitamo rifite ubushobozi budasanzwe bwo guhangana ningutu nubushyuhe bukabije kuruta ubundi buryo bwo guhagarika umutima. Umuyoboro wa bypass utezimbere ubushobozi bwabapakira kugirango bangane imbaraga ziboneka muri tubing na annulus kandi byoroshye kurekura ibyashyizwe mubikorwa. Gukomeza kwikuramo cyangwa kuremerera birakenewe kugirango bypass ya valve igume ifunze. Ibi ntibikwiranye n'iriba cyangwa inshinge ntoya yo kuvura.

Gukuramo impagarara / kwikuramo byateza imbere kugwa kwa tubing muri tension, kwikuramo, cyangwa kutabogama. Ibi nibisanzwe bikoreshwa muburyo bwo kugarura ibintu muri iki gihe. Bafite intera nini yimiterere yo guhagarika umutima, kwikuramo, cyangwa guhuza byombi gushiraho no gupakira ikintu. Guhitamo sisitemu hamwe nu rutonde rutandukanye bigira akamaro muburyo butandukanye bwimiterere. Hamwe nibi bikoresho, imbaraga zitanga imbaraga zifunze hamwe nuburyo bwo gufunga imbere kugeza igice gisohotse hamwe na bypass ya valve. Iyi valve ifasha mukuringaniza kimwe.

Ibi bikoresho birahinduka cyane kuruta ibindi bisubizo kandi bibaho muburyo bwo gukora no gutera inshinge.

Inzira zihoraho kandi zishobora kugarurwa zashyizwe hamwe na wireline yamashanyarazi cyangwa hydraulics kumurongo wa tubing. Gushiraho hamwe na wireline itanga umuvuduko nukuri mugihe urugendo rumwe-hydraulic-igenamigambi ryunguka mugushiraho pass imwe. Borohereza inzira yo gushiraho hamwe na headheads yazunguye. Ibi byiciro biranga kashe yimbere imbere. Ikirangantego cya kashe irimo gupakira elastomeric ikora kashe ihuza umusaruro wa tubing na packer bore. Umwanya wa kashe ya elastomeric muri bore itera iriba ryonyine.

Ubwoko bw'iteraniro ryemerera kugenda kashe mugihe cyo gukora no kuvura ibikorwa. Ubwoko bw'iteranirizo bwa kashe butanga kashe mubipakira kugirango bigabanye kugenda.

Ibisubizo bihoraho bya sealbore bitanga imikorere inoze kuruta ibice bishobora kugarurwa. Bafite ubunini bukomeye mugushushanya bigatuma bihenze.

Nka kimwe mu bikoresho byingenzi mugikorwa cyo kurangiza, abapakira biragoye cyane gukora tekiniki. Ibipaki bya Vigor bikozwe hifashishijwe uburyo bwagaragaye cyane kandi burigihe bigenzurwa bikurikije amahame ya API11D1 mugihe cyo gukora. Ni ukubera ko Vigor igenzura byimazeyo inzira ubwiza bwibicuruzwa burigihe burenze ibyo umukiriya yitezeho, niba ushishikajwe no gucukura no kurangiza ibikoresho byo gutema ibiti bya Vigor, nyamuneka ntutindiganye kuvugana nitsinda ryabahanga rya tekinike rya Vigor kugirango ubone ibyiza ibicuruzwa na serivisi nziza.
