Imikorere nibice byingenzi bigize Packer

Abapakira ni ibikoresho bya mashini bifite ibikoresho byo gupakira byashyizwe mubyakiriwe byabugenewe, bikoreshwa muguhagarika itumanaho ryamazi (amazi cyangwa gaze) binyuze mumwanya wa buri mwaka uri hagati yumuyoboro ufunga umwanya uri hagati yabo ”.

Ubusanzwe Packer ishyirwa hejuru yakarere itanga umusaruro kugirango itandukane intera itanga kuva kuri annulus cyangwa kubyara zone ahandi ku iriba.

Mu kuzuza umwobo wuzuye, isanduku yumusaruro ikoreshwa muburebure bwose bwiriba no kunyura mubigega. Umwobo wafunzwe ukora neza nkuburyo bwo kugenzura umusaruro wa hydrocarbone wifuzwa kandi nkinzitizi ibuza kongera kwinjiza amazi adakenewe, gaze, hamwe n’ibikomeye mu iriba.

Umugozi wimyitozo umaze gukurwaho, guhuza guhuza ibice bya diametre zitandukanye bikoreshwa mu iriba ku bujyakuzimu butandukanye kandi bigashyirwa mu bikorwa mu buryo buzwi nka Cementing. 'Sima' hano bivuga uruvange rwa sima hamwe ninyongeramusaruro zimwe na zimwe zinjizwa mu iriba kandi zuzuza icyuho kiri hagati yikibaho no kuzenguruka.

Nyuma y’iriba rimaze gukingirwa burundu kuva aho rikikije, isanduku igomba gutoborwa kugira ngo itange umusaruro uva mu bice bifatika by’ikigega cyitwa 'zone zones'. Gutobora bikorwa hakoreshejwe 'Perforating imbunda' yatangije ibisasu bigenzurwa biturika umwobo unyuze mu bice bimwe na bimwe bya kase (no mu kigega) kugira ngo habeho umusaruro wa hydrocarbone.

Parveen itanga umurongo wuzuye wapakira ibicuruzwa nibindi bikoresho - kuva mubipakira bisanzwe kugeza kubishushanyo byihariye kubidukikije byangwa cyane. Abapakira bacu barateguwe nkuko API 11 D1 yo Kwemeza Icyiciro V6-V0 hamwe nicyiciro cyo kugenzura ubuziranenge Q3-Q1.

Imikorere yabapakira: 

• Usibye gutanga kashe hagati yigituba no gufunga, indi mirimo yabapakira niyi ikurikira:
• Irinde kumanuka kumanuka wumugozi wigituba, ubyara impagarara nyinshi za axial cyangwa compression imizigo kumurongo.
• Shyigikira bimwe muburemere bwigituba aho hari umutwaro uhambaye wo kwikuramo kumurongo.
• Emerera ingano nziza yumuyoboro utemba neza (umugozi wa tubing) kugirango wuzuze igipimo cyateganijwe cyangwa igipimo cyo guterwa.
• Kurinda ikariso yumusaruro (umugozi wimbere) kwangirika kwamazi yaturutse hamwe numuvuduko mwinshi.
• Irashobora gutanga uburyo bwo gutandukanya uturere twinshi dukora.
• Fata amazi meza (yica fluide, packer fluid) muri case annulus.
• Korohereza kuzamura ibihimbano, nko kuzamura gazi ikomeza binyuze muri A-annulus.

Ibice by'ingenzi by'abapakira:

• Umubiri cyangwa mandel:

Mandrel nigice cyingenzi cyumupaki urimo amahuza yanyuma kandi atanga umuyoboro unyuze mubipakira. Irashobora guhura neza namazi atemba bityo guhitamo ibikoresho ni icyemezo cyingirakamaro. Ibikoresho byakoreshejwe cyane ni L80 Ubwoko 1, 9CR, 13CR, 9CR1Mo. Kubindi byinshi byangiza kandi bisharira Duplex, Super Duplex, Inconel nayo ikoreshwa nkuko bisabwa.

• Urupapuro:

Kunyerera ni igikoresho kimeze nk'igiti gifite imitwe (cyangwa amenyo) mu maso yacyo, cyinjira kandi gifata urukuta rw'igitereko iyo ipakira yashyizweho. Hariho ubwoko butandukanye bwibishushanyo biboneka mubipakira nka dovetail kunyerera, ubwoko bwa rocker bwinyandiko zinyuranye bitewe nibisabwa abaterankunga.

• Cone:

Umuhengeri urashishwa kugirango uhuze inyuma yinyerera hanyuma ugakora igitambambuga gitwara kunyerera hanze no murukuta rwikariso mugihe hashyizweho ingufu zashyizwe mubipakira.

• Sisitemu yo gupakira

Ibikoresho byo gupakira nigice cyingenzi mubapakira kandi gitanga intego yibanze yo gufunga. Iyo impapuro zimaze kwizirika ku rukuta, izindi mbaraga zashyizweho zongerera imbaraga sisitemu yo gupakira no gukora kashe hagati yumubiri wapakira hamwe na diameter yimbere yikibaho. Ibikoresho byakoreshejwe cyane cyane ni NBR, HNBR cyangwa HSN, Viton, AFLAS, EPDM nibindi. sisitemu yinyuma ya sisitemu.

• Gufunga impeta:

Gufunga impeta bigira uruhare runini mumikorere yabapakira. Intego yo gufunga impeta nugukwirakwiza imitwaro ya axial no kwemerera icyerekezo cyerekezo cyibikoresho bipakira. Impeta yo gufunga yashyizwe mumazu yo gufunga kandi byombi bigenda hamwe hejuru ya mandel yo gufunga. Imbaraga zose zo gushiraho zatewe nigitutu cya tubing zifunzwe mubipakira nimpeta.

Nkumwe mubakora inganda zambere zipakira, Vigor yitangiye gushyiraho amahame yinganda kubwiza no kwizerwa. Ba injeniyeri bacu bazana uburambe bwimyaka haba mubisabwa no gukoresha imirima yabapakira, biduha ubushishozi butagereranywa kuruhare rwabo mugikorwa cyo gucukura neza. Twunvise ko ipaki yujuje ubuziranenge ishobora kugira ingaruka zikomeye kumikorere n'umutekano, niyo mpamvu duhora dushora mubushakashatsi niterambere. Intego yacu nukuhanga udushya no gutanga urukurikirane rwibisubizo bikwiranye neza nukuri kwisi.

Kuri Vigor, dushyira imbere ibyo abakiriya bacu bakeneye, tureba ko ibicuruzwa byacu bidahuye gusa ahubwo birenze ibyateganijwe. Niba ushishikajwe no gucukumbura ibyapakiye bigezweho cyangwa ibindi bikoresho byo gucukura hasi, turagutera inkunga yo kubigeraho. Itsinda ryinzobere ryacu ryiteguye kuguha inkunga yubuhanga bwumwuga nibicuruzwa byujuje ubuziranenge bihuye neza nibyo usabwa. Intsinzi yawe ninshingano zacu, kandi turi hano kugirango tugufashe kubigeraho.
