Uburyo bwo Gupakira

Ibiro-Gushiraho cyangwa Gushiraho Gushiraho Abapakira

Ubu bwoko bwabapakira bushobora gushyirwaho bwigenga cyangwa bushobora gukoreshwa nkigice cyingenzi cyumugozi wigituba hanyuma ugashyiraho mugihe umugozi wamanutse.

Mubisanzwe abapakira bapima uburemere bakoresha kunyerera hamwe na cone ishobora gukoreshwa kugirango itange compression yibintu bya kashe, iyo gukurura amasoko cyangwa guhagarika guterana bishobora kwinjiza urukuta rwimbere rwikariso. Uburyo bwo kurekura impapuro zisanzwe ziboneka hifashishijwe igikoresho cya J cyifashishwa mugihe cyo gukora cyemerera uburemere bwumugozi kugabanuka bityo bigahagarika ikintu. Isohora ryibintu rishobora kuboneka mugutwara uburemere bwumugozi.

Ubu bwoko bwogupakira ibintu bizakenerwa gusa niba uburemere bushobora gukoreshwa mubipakira bishobora kutaba mumariba yegeranye cyane. Mubyongeyeho, abapakira bazafungura niba itandukaniro ryumuvuduko mwinshi ubaho munsi yuwapakira.

Gucomeka-gushiraho abapakira mubisanzwe bisaba 8000 kugeza 14,000 pound byibuze gushiraho imbaraga kubintu (packer element durometero nubushyuhe bwo gushiraho ubujyakuzimu nabyo bigomba gutekerezwa). Birumvikana ko ibi bishobora kuba ikibazo kiri munsi ya metero 2000 kuva uburemere bwimyanda ikenewe burakemangwa bitewe nubunini bwabapakira nubunini bwa tubing / uburemere kuri buri kirenge.

Gushiraho Impagarara Abapakira P.

Ubu bwoko bwabapakira nuburemere bwibikoresho bipakira biruka hejuru, ni ukuvuga sisitemu yo kunyerera hamwe na cone iri hejuru yikintu gifunga. Zifite akamaro kanini mubisabwa aho umuvuduko wo hejuru wo hasi umwobo bityo igitutu gitandukanye kuva munsi yabapakira kibaho. Iki kibazo kibaho mumariba yo guteramo amazi, aho igitutu cyo gutera inshinge kizafasha mukubungabunga abapakira. Hagomba kwitonderwa kugirango ubushyuhe ubwo aribwo bwose bwiyongere mu mugozi hamwe n’umugozi wagutse ntuzatanga imbaraga zishobora gukuramo abapakira.

Ihitamo risanzwe kubintu bitarangiye neza ni ubukanishi- bwashizeho-bipakira. Ibi birashoboka kuberako iriba ridakunze kwerekana muri rusange ubukungu bwifashe nabi kandi ubukanishi bwashyizweho nubushakashatsi bukunda kuba buhenze ugereranije na hydraulic set cyangwa wireline yashizweho na bagenzi babo.

Ibikoresho bya Roto-Imashini

Muri ubu bwoko bwabapakira, uburyo bwo gushiraho abapakira bukorwa na tubing rotation. Kuzenguruka k'umugozi nabyo

ihatira imiyoboro kunyerera inyuma yinyerera bityo igahagarika kashe, cyangwa ikarekura mandel y'imbere kuburyo uburemere bwigitereko bushobora noneho gukora kuri cones kugirango ihoshe ikintu gifunga.

Hydraulic-Gushiraho Abapakira

Muri ubu bwoko bwabapakira, uburyo bwo gushiraho biterwa nigitutu cya hydraulic cyakozwe mumurongo ukoreshwa kuri:

●gutwara piston kugirango uhindure urujya n'uruza rwa sisitemu na cone bityo bigizwe na kashe ya kashe, cyangwa ubundi

●kora urutonde rwinyandiko zo hejuru mubipakira hanyuma bizakosora aho bipakira hanyuma byemere impagarara gukururwa kubipakira no guhagarika sisitemu ya kashe.

Muburyo bwambere, iyo piston itwarwa na hydraulic hydratulike imaze gukora ingendo ya cone, kugaruka kwa cone bigomba gukumirwa nigikoresho gifunga imashini.

Kwemerera umuvuduko wa hydraulic kubyara muri tubing mbere yo gushiraho paki, inzira 3 zingenzi ziraboneka mugucomeka igituba:

● Kwishyiriraho icyuma kimeze nka Baker BFC icomeka imbere yigituba gikwiye nka Baker BFC yicaye.

●Gukoresha intebe ikoreshwa aho umupira ushobora kumanurwa kumurongo wa tubing. Iyo ushyizeho igitutu kirenze nyuma yo gushiraho paki, umupira nintebe byogosha hanyuma bikamanuka mumiriba. Ubundi buryo bwo gushushanya buranga collet yaguka izamanuka ikaguka mu kiruhuko iyo gukabya gukabije byunvikana, bityo bigatuma umupira unyuramo.

●Gukoresha uburyo butandukanye bwo kwimura sub, butuma amazi ya tubing yimurwa binyuze ku byambu kuri sub mbere yo gushyiraho abapakira. Umupira iyo umanutse uzicara kumurongo wagutse uzemerera igitutu kubyara. Iyo gukandamizwa bimaze gukoreshwa collet igenda hepfo kandi mubikora, ifunga valve yumuzingi kandi ituma umupira umanuka.

Gushiraho Amashanyarazi

Muri iyi sisitemu, ibikoresho bidasanzwe bya adaptori bihujwe nudupakira, hamwe cyangwa bidafite umurizo, kandi sisitemu ikoreshwa mu iriba kuri wireline hamwe nigikoresho gifitanye isano ryimbitse nka caking collar locator CCL Ku burebure bwashyizweho, amashanyarazi ikimenyetso cyanyujijwe kumurongo cyaka umuriro uturika buhoro buhoro kiri mubikoresho byo gushiraho bigenda byiyongera gahoro gahoro kandi bigakora ingendo ya piston kugirango ihagarike sisitemu ya kashe.

Ubu bwoko bwa sisitemu buganisha ku busobanuro bwimbitse bwimbitse kubapakira hiyongereyeho uburyo bwihuse bwo gushiraho / kwishyiriraho. Ingaruka ni ingorane zo gukoresha wireline mumariba maremare kandi kuba uwapakiye agomba gushyirwaho ukundi uhereye mugushiraho gukurikiraho.

Ibicuruzwa bipakira Vigor byakozwe kandi bikozwe hakurikijwe ibipimo bya API 11 D1, kuri ubu turashobora kuguha ubwoko 6 butandukanye bwabapakira, kuri ubu, abakiriya bakomeje gusuzuma cyane ibicuruzwa byacu bipakira, abakiriya bamwe bashyize imbere ibyo bakeneye, Abashakashatsi ba tekinike ba Vigor hamwe naba injeniyeri bagura bashaka ibisubizo byizewe kubakiriya bacu. Niba ushishikajwe nibicuruzwa bipakira Vigor, ibikoresho byo gucukura no kurangiza, cyangwa serivisi za OEM zabigenewe, nyamuneka ntutindiganye kutwandikira kugirango ubone ubufasha bwa tekiniki kabuhariwe.
